Defender 110 Accessories: What to Fit First on an L663
NinthX📌 Quick Summary
Which Defender 110 accessories should you buy first? The ones that use what a 110 has over a 90: a roof rated for 168 kg on the move, four side doors and up to 2,279 litres of loadspace, per Land Rover. Styling can wait.
- Top Priority: the roof, with bars for bikes or a full platform rack for real loads
- Everyday Basics: side steps, floor mats and a boot sill guard, about £521 / $686 together
- Best Value: fixed side steps at £242 / $319, about 81% less than Land Rover's own pair
- Budget Range: £52 for a sill guard up to about £2103 for a full overland setup
- Fitment: Defender L663 110 from 2020; always order the 110 version of length-specific parts
Search for Defender 110 accessories and two different cars come back mixed together. Some results are parts for the old Defender 110, which ended production in 2016. Others are for the L663 that arrived in 2020. Nothing from the first group bolts to the second, so check every listing says L663 or 2020 onward.
This guide is about the L663 only. And on that car, "what fits?" is the easy part, because most accessories are made for all three body lengths. The more useful question is which accessories make use of the 110's extra length. That is where your first few hundred pounds should go.
What does a 110 have that a 90 doesn't?
On paper the two cars share an engine line-up and most of their trim. The difference is 435 mm of extra wheelbase, per the L663 entry on Wikipedia, and three things that come with it.
| Defender 90 | Defender 110 | |
|---|---|---|
| Wheelbase | 2,587 mm | 3,022 mm |
| Side doors | 2 | 4 |
| Seats | up to 6 | up to 7 |
| Dynamic roof load | 118 kg | 168 kg |
| Static roof load | 300 kg | 300 kg |
| Max loadspace | 1,563 litres | 2,279 litres |
| Source | 90 page | 110 page, Wikipedia |
The roof row matters most. Both cars take 300 kg parked, which Land Rover pitches for its rooftop tent. On the move, the 110 is rated for 50 kg more, with off-road tyres and an Expedition Roof Rack fitted, according to Land Rover's specification notes.
Land Rover's own packs point the same way. On its personalisation page, the Explorer Pack includes a roof rack, a roof ladder and a side-mounted gear carrier, among other parts. Fixed side steps and a rear scuff plate turn up in the Urban and Adventure packs. Those five parts are the core of this guide.
Is a full roof rack worth it on a 110?
On a 90, a heavy platform rack eats a big share of the 118 kg dynamic rating before you load anything. On a 110 there is room left for gear. That is why the rack question is a 110 question.
Our Aluminum Expedition Roof Rack for Defender 90/110 costs £1179 / $1555 in the 110 size, in black or silver. It is a full-length platform that bolts to the factory roof points, no-drill. Land Rover's own 110 Expedition Roof Rack lists at £1494.97 at LR Parts, so ours costs about 21% less.
That gap is real but not dramatic. The genuine rack makes sense if you want a factory part number and dealer fitting. Ours makes sense if you want the same full-length platform and would rather keep the £316.
Whichever you fit, respect two limits: the car's roof rating and the rack's own. LR Parts lists the genuine rack at 132 kg depending on tyres. The rack's weight counts against the car's figure too, so a heavy rack leaves less for the gear on top.
If the roof only ever carries bikes, a kayak or a roof box, you don't need a platform. Our Roof Rack Cross Bars for Defender 90/110 cost £204 / $269, lock to the factory rails and come in a 110 length.
Buy this if: you camp, run a rooftop tent or need the roof for bulky gear most weekends.
Skip if: the roof only sees bikes or a kayak; cross bars do that job for £204.
How do you get up to a loaded roof?
Once the roof carries real weight, standing on a tyre stops being an option. There are two ways to fix it, and the right one depends on where you load from.
The Aluminum Rear Door Ladder for Defender L663 costs £322 / $425 and climbs beside the tailgate, which suits loading from the back. The Side Access Roof Ladder for Defender L663 costs £413 / $545. It bolts to the side panel behind the rear doors and folds away when you drive.
If you camp off the roof and keep opening the tailgate, the side ladder stays out of the way. Our rear door vs side ladder guide covers the trade-offs in detail.
Why do side steps matter more on a 110?
Four side doors and up to seven seats mean more people climbing in, children included. The same step also gets you within reach of the roof bars from the side.
Our Fixed Side Steps Running Boards for Defender L663 cost £242 / $319 in the 110 & 130 length, rated to 220 kg according to the listing. Land Rover's fixed steps for the 110 (VPLEP0525) list at £1307.68 at LR Direct. That makes ours about 81% less, the biggest gap in this guide.
Land Rover sells its own version too, as part of the Urban Pack. The trade-off is clearance. Any fixed step sits below the sills, so take deep ruts slower. Our side steps buying guide compares fixed and deployable steps.
How do you protect a boot that big?
A 110 holds up to 2,279 litres behind the front row, according to Land Rover. That's 716 litres more than a 90. Fold the rear seats and heavy kit slides in over the boot sill, and that sill is the first thing to scratch.
Land Rover puts a rear scuff plate in both its Adventure and Urban packs for that reason. Our Trunk Sill Scuff Plate Guard for Defender L663 costs £52 / $68. It is brushed 304 stainless steel and sticks on with automotive tape, so there are no tools involved.
Inside, the NINTHX All-Weather TPE Floor Mats Liners For Defender L663 cost £227 / $299 for the 110. Pick the LHD or RHD version to match your car. The set covers the front and second-row footwells and uses the factory retention clips. Running the third row? Those footwells are not included.
For loading after dark, the LED Trunk Cargo Light Upgrade for Defender L663 costs £174 / $229. It replaces the trim panel above the boot opening with one carrying two LED panels, and plugs into the factory wiring. Our TPE vs rubber floor mats guide helps if you are still choosing mats.
Where does the overflow go when the boot is full?
On a 110 the answer is the side of the car. The Exterior Side Storage Box for Defender L663 costs £337 / $445, in a choice of body colours. It is lockable and sealed, and it bolts to existing mounting points. Land Rover's genuine Side-Mounted Gear Carrier lists at £895.52 at LR Parts, so ours is about 62% less.
The box and the side ladder both use the panel behind the rear doors, so decide which side gets which before ordering both. Our side box essentials checklist covers what is worth keeping in it.
How much should you budget for a 110?
Most owners build in stages. These three tiers use our live UK and US prices:
| Tier | What it includes | NinthX price | Genuine equivalent |
|---|---|---|---|
| Tier 1: Everyday | Sill guard, 110 floor mats, side steps | £521 / $686 | steps alone £1307.68 |
| Tier 2: Roof ready | Aluminum Expedition Roof Rack for Defender 90/110 plus rear door ladder | £1501 / $1980 | rack alone £1494.97 |
| Tier 3: Overland | Platform rack, side ladder, side storage box, boot light | £2103 / $2774 | rack and gear carrier £2390.49 |
Not sure where to start? Answer three questions in order:
- Does anyone struggle to climb in? Fit side steps first.
- Will the roof carry more than bikes? Then a platform rack and a ladder; otherwise cross bars.
- Is the boot full before you leave? Add the side storage box.
The Bottom Line: What should a Defender 110 owner fit first?
Spend first on what the 110 does better than a 90: the roof, the doors and the boot. For most families, that means side steps and boot protection now. Add the Aluminum Expedition Roof Rack for Defender 90/110 when the roof starts doing real work.
Grilles, gloss black trim and light bars can wait, because they fit every body length and don't use the extra space; our Defender black pack guide covers that stage. For the full picture across all three body lengths, see our Defender accessories guide.

The prices we used were checked live on our UK and US storefronts on 26 October 2026. Genuine prices come from the UK retailer pages linked above. We have not tested load ratings ourselves, so every real-world limit quoted here is Land Rover's published figure or the product listing's.
FAQ
What are the best Defender 110 accessories for a family car?
A: Side steps, floor mats and a boot sill guard. They help with the two things a family 110 does every day: people climbing in and luggage sliding over the sill. Together they cost about £521 / $686 from us.
Do Defender 90 accessories fit a 110?
A: Many do, including grilles, lights and interior trim. Roof racks, cross bars, side steps and floor mats are length-specific, so order the 110 version. Our 90 vs 110 vs 130 fitment guide lists which parts are shared.
How much weight can a Defender 110 roof carry?
A: Land Rover quotes 168 kg on the move with off-road tyres and an Expedition Roof Rack, and 300 kg parked. The OCTA is lower: 100 kg on 22-inch wheels with all-season tyres, and zero in OCTA mode, per the specification notes.
Roof rack vs cross bars: which is better on a Defender 110?
A: Cross bars suit bikes, kayaks and roof boxes, and cost £204 / $269. A platform rack suits rooftop tents and loose gear. If the roof will carry more than bikes most weekends, the rack is worth it.
When should I choose genuine Land Rover accessories?
A: When the car has to stay original, for example on a lease, or when you want the dealer to fit everything. Otherwise the side steps and gear carrier above cost 62% to 81% less.
How do I check an accessory fits my 2026 Defender 110?
A: Check that the listing names the 110 and your model years. Fitment years vary by product, so for a 2026 model-year car or an OCTA, send us your VIN before you order and we will confirm.
