Land Rover Defender 110 Accessories: A Practical Build Guide

Build guide · Land Rover Defender 110 (L663) · Updated September 2026

The Defender 110 gives you space. It does not give you a system. There is room above the roof, room behind the seats, a rear door that swings wide, and a spare wheel doing nothing but hanging there — and most owners fill all of it, then spend the trip digging. This guide is organized the way we actually decide what goes on a truck: by the kind of trip you take, with the numbers that decide whether a part works on your car.

1. Start with your own car

Before you buy anything, spend five minutes with your own car. Specifications for the L663 vary by market, model year, body style and options, so the only figures that count are the ones printed for your vehicle — not the ones in a forum post.

What the handbook tells you

What to check on the car itself

These are the details that decide whether a specific part goes on your specific 110. Five minutes now saves a return later.

2. The roof: the OX PRO platform and what bolts to it

The roof is the foundation, because almost everything else up there attaches to it. Fitting a rack after the roof is already loaded is a bad afternoon, so this is the decision to take time over.

What separates a good platform from a cheap one

Roof platforms for the 110 come in two broad kinds: universal bar sets adapted to fit, and full-length platforms cut for this body and its rails. They are not equivalent, and the difference shows up on the fifth day of a trip rather than in the product photo. Five things are worth checking on any of them.

• Dynamic rating including the rack's own weight. A 66 lb (30 kg) rack does not leave you the whole allowance.
• Added height. The most common source of buyer's regret, usually discovered in a car park rather than on a trail.
• How it sits on the roof. The 110 carries a roof platform on its factory rails, so what matters is whether the brackets were cut for those rails or adapted from a universal kit. Generic feet spread the load into fewer places, and that is where noise and movement start.
• Accessory ecosystem. A platform with no way to attach a shovel, a light or a table is a platform you will end up drilling.
• Wind noise. Universal platforms adapted to the 110 are where most complaints come from. Slat spacing and deflectors matter.

That list is the specification we built the OX PRO platform against. It mounts on the factory roof rails with no drilling, the slat pattern is shared across the whole OX PRO range so accessories move between builds, and both load figures are published below — including the platform's own weight, which is the number most often left out.

The OX PRO crossbars are ours, not off the shelf

The bars on this platform are a 90 × 25 mm profile extruded from a die made for us, wider than a standard slat. Two details change how it lives with you. There is a channel along the profile that takes cabling for lights or a compressor, so nothing is cable-tied to the outside of a bar and nothing chafes. And the holes are pre-drilled at fixed positions, so a mount bolts to a known point instead of relying on a T-nut you tighten and hope stays where you put it. Eight bars, 296 mm apart, on the 110.

The OX PRO System keeps growing

The bar profile matters because of what happens afterwards. The OX PRO platform is not a finished product you buy once — it is the mounting language for everything that comes later, and the same pattern runs across the whole range. A build that starts as a bare platform and a box ends up, three seasons on, carrying lights, boards, an awning and a kitchen, without a single new hole in the car.

Buy the platform once, add the rest over three seasons. That is the whole argument for a system rather than a rack — and it is why the bar profile above is worth two paragraphs. See the full range: OX PRO System and Roof Rack Accessories.

OX PRO on the 110, with the numbers

The platform has an integrated mounting point for the camping table, which is the part people underestimate. It lives in the dead air under the rack, so a full cooking surface costs you nothing in the cargo area.

• OX PRO Roof Rack — Defender L663 (110)Full-length platform, no drilling. Mounts on the factory roof rails.
• OX PRO Under Roof Rack Camping TableSlides out from under the rack. Rain, snow, mud, UV — it does not blink. Hurricanes remain untested.
• Awning Mount — Quick ReleaseStainless, keyed quick-release lock, up to 66 lbs (30 kg). Small and Large — pick by the awning, not the car.
• SET: Roof Rack + 2 MOLLE PanelsPlatform and body-side storage bought together.

3. Body sides and the spare wheel

Two zones on the 110 are almost always wasted, and they do different jobs. The flat body sides take the things you reach for during the day. The spare wheel takes the heavy, dirty things you would rather never bring inside.

The body sides

The external panel is aluminum, weighs 11 lbs (5 kg) and carries a dynamic load of 55 lbs (25 kg) — enough for a full water canister, a shovel or a recovery board. It has M5 rivnut points across it, so mounts and pouches bolt straight on.

Two brackets belong here more than anywhere else on the car. The jerry can mount puts 20 litres of fuel or water on the body side, upright and outside the cabin. And the Quick Mount System is the universal answer to everything you do not want bolted on permanently — it goes on and comes off in seconds, and it is the same bracket family used up on the platform, so a mount bought for the roof works down here too.

• External MOLLE Panel — Defender L663Aluminum, 11 lbs (5 kg), 55 lbs (25 kg) dynamic, no drilling.
• Jerry Can Mount20 L of fuel or water on the panel, outside the cabin. Canister not included.
• Quick Mount SystemUniversal bracket for kit that comes on and off. Shared with the OX PRO platform.

The spare wheel

The spare wheel is the most wasted real estate on a 110. One stainless wheel mount turns it into a third storage zone, and every bracket stacks onto that same base — a tray for dirty kit, a traction-board bracket, a holder for the propane cylinder you cook on. Buy the mount once; the rest bolts to it. On day four of a trip, having the muddy gear outside the cabin is worth more than it sounds on day one.

The propane holder is the one people forget until they have tried carrying a cylinder inside the car. It is aluminum, weighs 11 lbs (5 kg), takes 170 × 235 × 220 mm on the wheel and adjusts to both 5 lb and 10 lb cylinders, with a locking mechanism that keeps it still on a rough track.

• Universal Wheel MountStainless base. Everything below bolts to it.
• Spare Wheel Tray / Traction Boards BracketBoards and dirty kit outside the cabin.
• Propane Tank Holder — 5 lb / 10 lbAdjustable, aluminum, 11 lbs (5 kg). Gas on the wheel instead of in the load bay.

4. Inside: the cabin and the load bay

The same idea runs inside the car — in a different place, and doing a different job. Up top the platform is the rack. Behind the seats it is the OX PRO Roof Shelf: one piece of steel on factory points, M5 rivnut positions across it, and the space underneath left open on purpose. That space is a mounting slot, not a shadow. What goes in it is a decision you can change whenever the way you travel changes.

What mounts under the OX PRO Roof Shelf

Fit the shelf and you have not bought a shelf — you have bought the point everything below attaches to. One slot, one accessory at a time, all of it bolted rather than drilled, all of it reversible.

Two numbers worth having: the YAK mount weighs 1.5 lbs (0.7 kg) and takes 140 × 135 × 360 mm under the shelf, so two or three sit side by side; the ELK compartment is 400 × 440 × 70 mm and carries 22 lbs (10 kg). Both come with a cord that keeps the chair in place on a rough track, and both fit with two bolts and no drilling.

The point of the slot is that it is not permanent. Take the net off and the same space holds chair storage or a tool-box mount. Stop using the car off-road for a season and strip it back to a bare shelf. Nothing was drilled, so nothing has to be undone.

• OX PRO Roof Shelf — Defender L663 (110)One-piece steel, M5 rivnut points, no drilling. Static 66 lbs (30 kg) / dynamic 26 lbs (12 kg).
• Universal Under Shelf NetNew. Fits every Bison Gear shelf, including the Defender L663. Off in seconds when you want the space back.
• YAK Chair Mount / Under The Shelf CompartmentChairs under the shelf instead of across the floor.
• SET: Roof Shelf + Universal Net — Defender L663 (110)The shelf and the net bought together.

At floor level

The shelf splits the space horizontally. The rest of the load bay is about using the volume along the sides and getting to the fridge without unloading the truck.

The slide takes both ARB and Dometic fridges, in two sizes — but measure the base of your own against the drawer dimensions above rather than going by model name, because fridge feet and handles vary more between models than the advertised capacity suggests.

One number from that table is worth reading twice: the shelf's dynamic figure, 26 lbs (12 kg) moving. That is sleeping bags, jackets, a tent inner — not a toolbox. Everything heavy stays on the floor, which is exactly the point of splitting the space.

• Cargo Basket — Defender L663 (110)Mounts on factory body points. Fully reversible.
• Fridge Slide / Cargo Slide / Tilted Fridge SliderReach the fridge without unloading the truck. Fridge not included.
• All interior accessoriesShelves, nets, baskets, panels and sliders across the range.

5. The rear door as a work surface

The 110's side-opening rear door is the most natural work surface on the car, and a drop-down table is the way to use it without carrying a folding table in a bag. It stays on the vehicle, folds flat when closed, and turns a roadside stop into a kitchen in one motion.

Two practical notes. It closes in one motion with locking pins, which matters the fiftieth time you do it in the dark. And it carries a MOLLE field on the face, so a small organizer or a utensil pouch travels with it. See it here: Drop-Down Tailgate Table — Defender (L663).

6. Lighting

The usual split is distance light forward and low-power scene light where you are standing. Most people over-buy the first and under-buy the second, then discover that a 42-inch bar is no help at all when you are looking for a fork in a cargo box. All four below mount to the OX PRO System, and on the roof the cable runs inside the bar channel rather than along the outside of it.

• Siberia XPA SR LED Bar 42″Distance light for the hours you did not plan to still be driving.
• SPARROW Dimmable Dome LightCabin light you can turn down instead of off.
• STORK Dimmable LED Strip LightMounts under the OX PRO Roof Shelf and lights the whole load bay from above.
• SWIFT 45° Angled LED Work LightAngled work light for the area beside the car.

7. Three builds by trip type

Categories are how shops organize products. Trips are how people actually use them. Here is the same range sorted the second way.

Weekend setup — two people, two nights

The mistake here is over-building. You need one good work surface, light where you are standing, and storage that does not live in your footwell. The truck still has to be usable on Monday morning.

• Drop-Down Tailgate Table — the piece that changes every single trip from day one
• Cargo Basket — small items off the floor
• SPARROW Dome Light
• YAK Chair + Chair Mount or the ELK with an Under The Shelf Compartment — chairs that stow on the vehicle
• Fridge Slide / Cargo Slide — cold food reachable from the back, without unpacking

Long expedition — two weeks or more, off-grid

Everything from the weekend setup stays on the car — table, basket, lighting, chairs, fridge slide. This is where the roof earns its keep on top of it, and where a system beats a pile of parts: fuel, water and recovery gear move outside the cabin, and the kitchen moves under the rack. In the order we would add them:

• OX PRO Roof Rack + Under Roof Rack Camping Table
• OX PRO Roof Rack Panels
• Awning Mount — Quick Release
• External MOLLE Panel with a Jerry Can Mount on it
• Universal Wheel Mount with tray, board brackets and the Propane Tank Holder
• Siberia XPA SR LED Bar 42″ and a STARLINK Mount if you work from the road

Family rig — kids, a dog, and everything at the bottom

Interior organization does the heavy lifting here, and our own sales figures back that up: organization outsells racks by a wide margin, because it is what changes daily life in the car rather than once a year.

• OX PRO Roof Shelf with the Universal Under Shelf Net or chair storage underneath
• Fridge Slide or Cargo BOX with Tilting Slider
• STORK LED Strip Light under the shelf
• ELK Big Folding Camp Chair

8. The order we would build in

There is no single right sequence. It turns on one question: is a roof platform part of your plan at all?

If the roof is in the plan, start with the roof

Fit the platform first. Everything that goes up top attaches to it, and retrofitting a rack under an already-loaded roof — tent off, boxes off, lights re-routed — is a day nobody enjoys. More importantly, the platform decides what you can add afterwards. The bar profile, the slat spacing and the mounting pattern are what every bracket, light, panel and table bolts to, so choosing the platform is really choosing your accessory range for the next few years. Get that decision right and the rest of the build is a series of small, cheap additions rather than a series of compromises.

After the platform: panels and the under-rack table, then the awning and lighting, then the body sides and spare wheel — those last, once you know what actually travels with you.

If you are not going up on the roof, work from the inside out

The tailgate table first: it changes every single trip and needs nothing else fitted. Then the OX PRO Roof Shelf, which is the interior equivalent of the platform — fit it and the net, chair holders and under-shelf lighting all have somewhere to go. Baskets and a fridge slide after that. Lighting last, because by then you know where you are standing in the dark.

Everything above mounts to what the car already gives you — the platform on the factory roof rails, everything inside on factory fixing points. Nothing is drilled, nothing is cut, and every install is reversible — which matters for resale, for lease returns, and for the simple reason that a hole in a Defender roof is permanent while your build plans are not. All of it is designed and manufactured in Poland, from the first sketch through field testing to the finished product.

Build it once. Build it in the right order. Then go.

9. Common questions

Can I fit a roof tent to a Defender 110 with this rack?

The platform is rated 880 lbs (400 kg) static, which covers a tent plus occupants comfortably. The constraint is the dynamic figure — 265 lbs (120 kg) while driving, and that has to include the 66 lb (30 kg) rack itself plus the tent. Check the tent's own weight and your vehicle's published roof limit rather than assuming.

Will accessories I buy now still fit if I change vehicle?

Anything that mounts to the OX PRO bar profile — lights, panels, board brackets, quick mounts, tie-downs, straps — moves to the next OX PRO platform unchanged. The Universal Under Shelf Net is the same story inside: it fits every Bison Gear Roof Shelf, so it moves with you. Only the platform and the shelf themselves are cut for a specific body.

Do Defender 110 parts fit the Defender 90?

Not the ones referenced to the body length or the load space. Roof racks, roof shelves and cargo baskets listed for the L663 (110) are specific to that body. Universal parts — wheel mounts, brackets, lighting, the under-rack table, the under-shelf net — carry across. Always check the fitment note on the individual product.

Does anything here need drilling?

No. The roof platform mounts on the factory roof rails, and every part inside the car uses factory fixing points. Nothing is drilled, and every install is fully reversible.

How much height does the roof rack add?

Roughly 2.8–3.1 in (7–8 cm). Measure your car as it stands now, add that, and check it against the garages and car parks you use regularly. This is the single most common regret with any roof platform.

What is the difference between static and dynamic load?

Static is what the structure holds while parked. Dynamic is what it holds while you are driving, and it is always lower. Buy against the dynamic number.
