INEOS Grenadier (2023 Onwards) 40mm Wide Wheel Arches

More arch. More tyre. More Grenadier. Wider, bolder and properly planted, these wide-track arches give the Grenadier a serious off-road stance with an OEM-plus finish that looks like it left the factory this way. The extra width is not just for show. It makes room for our 20" deep concave wheels with chunkier tyres, the combination that really changes how the truck sits. Each arch carries a KAHN® Union Flag badge, cast in zinc alloy and finished in polished chrome and satin black, set into its own recess. A small detail. You will notice it every time you walk up to the truck. Make it yours Supplied in satin black ABS. Leave them as they come for a rugged, utilitarian look, or colour-code them to the body for a cleaner, more luxurious finish.

Yes. They follow the body lines and mounting points of every INEOS Grenadier from 2023 onwards, sit flush with the factory trims and need no modification. If you are unsure, get in touch before ordering. What is the difference between the 15mm and 40mm arches? The 15mm set adds a subtle step out from the factory body. The 40mm set goes further: a bolder, off-road look and the room to run our 20" deep concave wheels with chunkier tyres. Can I fit bigger wheels and tyres with these arches? Yes. The 40mm arches are designed to work with our 20" Mondial Retro and G22 deep concave wheels and chunkier tyres. Tell us your planned wheel and tyre setup when you enquire and we will confirm it. Are they suitable for off-road driving? Yes. The ABS construction is built for mixed terrain and everyday use, and handles mud, road debris and cleaning well. Do I need to paint them? No. They can be fitted in satin black as supplied, or colour-coded to the body. Do I need professional fitting? It is recommended. Each arch needs to be aligned cleanly with the factory trims so it sits tight, with no gaps or stress points. Allow approximately 2 hours. We can fit them in-house at an additional cost. Is VAT included? Yes. All prices include VAT.
