A Tesla Model 3 body kit in the UK costs £499 for the complete KITS UK gloss black package, rising to £769 with professional fitting included — and up to £1,416 for a full carbon fibre package. That single number answers the question most Model 3 owners search for, but the more useful question is what you actually get for it, and whether the gloss black or carbon route makes sense for your car.
The Model 3 is one of the cleanest factory designs on UK roads — which is exactly why a well-chosen styling kit transforms it so effectively. The minimalist body means every added line is visible. A front splitter, side extensions and a rear diffuser don't fight the car's design language; they sharpen it, taking the Model 3 from "clean" to "deliberate" without touching the car's structure, range or everyday usability.

Tesla Model 3 Body Kit: Complete Price Table
KITS UK offers two full-package routes for the Model 3, plus individual carbon fibre components for owners building in stages. Verified pricing as of July 2026:
| Package / Part | Finish | Supply Only | With Fitting | Availability |
|---|---|---|---|---|
| Tesla Model 3 Body Kit — Full Package | Gloss Black | £499 | £769 | ✅ In stock |
| Tesla Model 3 Full Carbon Package | Carbon Fibre | £1,416 | £1,686 | ⚠️ Check live page — sells out |

One number worth noticing: professional fitting adds £270 to either full package — the same fitting price whether you choose the £499 gloss black kit or the £1,416 carbon package. On the gloss black kit, that means a professionally fitted, warrantied, complete exterior transformation for under £800 total.
What's Included in the KITS UK Tesla Model 3 Body Kit?
The gloss black package includes five components covering the front, sides and rear of the car in a single order:
Front Splitter
The splitter defines the lower front edge of the car and is the single most visible change from the front. On the Model 3's smooth factory bumper, it adds a sharper, lower, more planted look — the difference between a standard car and one that reads as an intentional build.
Side Extensions
Side extensions run along the sills, visually lowering the car's profile and connecting the front and rear styling so the kit reads as one coherent design rather than separate add-ons.
Rear Diffuser
The rear diffuser replaces the visual flatness of the Model 3's lower rear bumper with structure and depth. Because the Model 3 has no exhaust to break up the rear view, the diffuser carries even more visual weight on this car than it does on a petrol equivalent.
Rear Side Splitters
Smaller corner details flanking the diffuser that complete the lower rear of the car and frame the diffuser properly.
Boot Spoiler
A subtle lip spoiler on the boot lid that finishes the silhouette — the same understated approach Tesla itself uses on the Performance model.
All components are finished in gloss black and manufactured for accurate fitment on the Tesla Model 3. This is an exterior styling product only: not a kit car conversion, no structural modifications, and not an OEM or genuine Tesla part.
Gloss Black vs Full Carbon: Which Route?
KITS UK offers the Model 3 kit in two distinct finishes, and the right choice depends on budget and the look you're building toward:
| Factor | Gloss Black Kit (£499) | Full Carbon Package (£1,416) |
|---|---|---|
| Look | Clean, OEM+ — matches Tesla's factory gloss black trim | Premium, motorsport-inspired weave texture |
| Price with fitting | £769 | £1,686 |
| Kit contents | Splitter, side extensions, diffuser, rear side splitters, boot spoiler | Splitter, diffuser, side extensions (3/4 length), boot spoiler |
| Availability | ✅ In stock | ⚠️ Sells out — check the live page |
| Best for | Most owners — daily drivers, OEM+ builds, budget-conscious transformations | Owners who want a genuine premium carbon finish and don't mind the investment |
For a deeper comparison of the two materials — durability, finish, cost logic — see the KITS UK guide: Carbon Fibre vs Gloss Black Body Kits.
Is a Tesla Model 3 Body Kit Worth the Money?
For most Model 3 owners wanting a complete exterior transformation, the £499 full package is one of the strongest value propositions in the KITS UK range — here's the honest breakdown:
Visual transformation. The Model 3's minimalist factory design means styling additions register more strongly than they do on a busier design. The combination of splitter, extensions and diffuser changes how the car reads from every angle — particularly the rear, where the absence of exhaust tips otherwise leaves the lower bumper visually empty.
One order, one finish. Buying a splitter from one supplier and a diffuser from another almost always produces finish mismatches that only become obvious once both are on the car. A single package manufactured together removes that risk.
Everyday usability preserved. These are cosmetic exterior parts. The car's structure, practicality and driving character are unchanged — the package is explicitly designed to maintain the original usability of the vehicle.
Who should buy it: Model 3 owners who want the complete look in one order, value a consistent finish, and plan to keep the car long enough to enjoy it.
Who should think twice: owners planning to sell imminently, or anyone who only wants one specific change — in which case an individual carbon component may be the better entry point.
Tesla owners are a different customer to our BMW and Mercedes builds — the brief is almost always "sharpen it, don't shout." The gloss black kit suits that perfectly because Tesla already uses gloss black trim from the factory, so the finished car looks like a specification Tesla could have offered rather than an aftermarket add-on.
The rear diffuser is consistently the part Tesla owners underestimate. With no exhaust to anchor the rear view, the lower bumper on a standard Model 3 is a blank space — the diffuser and rear side splitters fill it with structure, and it's usually the change people comment on first once the car is finished.
If you're deciding between supply-only and fitted, price the difference honestly: fitting adds £270 and includes a lifetime fitting warranty on the work. For a five-piece kit where splitter and diffuser alignment is highly visible, that's the difference between a finish you check twice and one you never think about again.
Supply Only vs Professional Fitting
| Factor | Supply Only / DIY | Professional Fitting at KITS UK |
|---|---|---|
| Total cost (gloss kit) | £499 | £769 |
| Tools required | Trim tools, fixings, basic kit | None — handled by KITS UK |
| Time required | Variable — allow a day for the full kit | Workshop appointment |
| Alignment risk | Higher — splitter and diffuser alignment is highly visible | Low — technicians experienced with the platform |
| Warranty on fitting work | None | Lifetime fitting warranty |
| Best for | Confident DIY owners | Full-package installs, first-time fitment, lease/finance cars where the finish must be right |
Fitting takes place at the KITS UK workshop: Unit 3C Onward Park, Phoenix Ave, Green Lane Industrial Estate, Featherstone, West Yorkshire WF7 6EP — open Tuesday–Friday 9am–5pm and Saturday 9am–4pm, with a customer waiting area (WiFi, drinks, Smart TV) if you'd rather wait with the car.
Why Professional Fitting Matters on a Tesla
- Splitter alignment — the front splitter defines the car's lowest visible line; even a few millimetres of asymmetry is noticeable from the front
- Diffuser and rear side splitters — three separate rear components need to sit flush and even with each other and the factory bumper lines
- Panel-safe installation — reduces the risk of damage to factory clips, bumper tabs or paintwork, which matters on any car but especially on lease and finance vehicles
- Secure fixing — properly fitted components won't work loose or vibrate at motorway speed
- Lifetime fitting warranty — every install carried out by KITS UK is warrantied for life
Recommended Tesla Model 3 Upgrade Order
The full package at £499 makes staging less necessary on the Model 3 than on platforms where a full kit costs four figures — but if you're building in stages with individual carbon components, this is the order that delivers the strongest result at each step:
| Step | Upgrade | Why This Order |
|---|---|---|
| Step 1 | Front Splitter | The highest-impact single change — defines the front of the car immediately. |
| Step 2 | Rear Diffuser | Fills the visually empty lower rear bumper — the Model 3's biggest styling gap from the factory. |
| Step 3 | Side Extensions | Connects front and rear, visually lowering the whole profile. |
| Step 4 | Boot Spoiler | The finishing detail that completes the silhouette. |

| Option | Price | Visual Impact | Best For | Overall Value |

| Full Gloss Black Package | £499 (£769 fitted) | ★★★★★ | Complete transformation, consistent finish, strongest £-per-impact | ★★★★★ |
| Full Carbon Package | £1,416 (£1,686 fitted) | ★★★★★ | Premium builds where the carbon finish itself is the point | ★★★★☆ |
Tesla Model 3 Fitment: What to Check Before Ordering
- Standard Model 3 — the kit is designed for the standard Tesla Model 3 and fits without structural modification
- Highland facelift (2024+) — the Highland update changed the front and rear bumper profiles; confirm your exact model year with the KITS UK team before ordering
- Performance model — the factory Performance spoiler occupies the boot lid; confirm spoiler fitment with the team if your car is a Performance
- Existing accessories — mud flaps, PPF or existing splitters can affect fitment; mention them when ordering
If in any doubt, contact the KITS UK team with your model year before ordering — confirming fitment takes minutes and avoids a return.
EV-Specific Practicality Notes
- These are cosmetic styling parts, not functional aero — the package is designed for visual enhancement while maintaining the car's original structure and everyday usability
- Front splitter ground clearance — as on any car, the splitter sits closer to the road than the factory bumper; normal awareness around kerbs, steep driveways and car-park stops is sensible
- Charging access unchanged — no component in the kit interferes with the charge port
- Lease and finance cars — professional fitting is the sensible route where the finish and the condition of factory fixings matter at hand-back; discuss your situation with the team
- KITS UK does not provide legal guarantees regarding road-use compliance — for guidance on vehicle modifications see GOV.UK vehicle modification guidance, and if in doubt for your circumstances, consult your insurer
How to Look After Tesla Model 3 Styling Parts
- Wash regularly — gloss black and carbon finishes show road film more readily than body paint
- Use a pH-neutral shampoo and clean microfibre towels to avoid swirl marks
- Avoid abrasive products not designed for gloss or carbon surfaces
- Take care around the front splitter when parking nose-in against kerbs
- Inspect the lower components after winter driving or rough roads
Common Mistakes When Buying a Tesla Model 3 Body Kit
- Mixing suppliers: a splitter from one brand and diffuser from another rarely match in finish once side by side on the car
- Not confirming Highland vs pre-Highland: the 2024 facelift changed the bumper profiles — always confirm your model year
- Ignoring fitting cost: if you're planning professional fitting, budget the £270 from the start rather than discovering it at checkout
- Assuming "body kit" means kit car: this is a bolt-on styling package for a standard Model 3, not a conversion — but the distinction matters for insurance conversations, so describe it accurately
- Buying on price alone: the cheapest unbranded kits online are often inconsistent in fitment, and a poorly aligned splitter is worse than no splitter

Final Thoughts
The Tesla Model 3 Body Kit from KITS UK costs £499 supply-only or £769 professionally fitted — a complete front-to-rear transformation covering splitter, side extensions, diffuser, rear side splitters and boot spoiler, finished in gloss black that matches the car's factory trim. For owners who want the premium route, the Full Carbon Package sits at £1,416 (£1,686 fitted), stock permitting.
On a car as visually clean as the Model 3, the kit does exactly what good OEM+ styling should: it sharpens what's already there. And with fitting adding a flat £270 with a lifetime warranty on the work, the fitted route is one of the easiest recommendations in the KITS UK range.
