Premium galvanised Land Rover Defender chassis with innovative bolt on engine mount plates. Designed for restorations and engine conversions with no welding required on the galvanised chassis. Available for Defender 90, 110 and 130.
Build your Defender the right way with our premium galvanised Land Rover Defender chassis, engineered specifically for restorations, engine conversions, and high performance custom builds.
Unlike conventional galvanised chassis that require grinding away the protective zinc coating before welding engine mounts, our innovative design features bolt on engine mounting plates. The chassis itself is fully galvanised for maximum corrosion resistance, while the removable bare steel mounting plates allow engine mounts to be welded and modified without damaging or contaminating the galvanised chassis.
Galvanising and engine conversions have never got on. You buy a galvanised chassis because you want the vehicle to outlast you, and then the first thing the conversion asks you to do is grind the zinc off and weld to bare steel, in the enclosed corners of the chassis where corrosion starts and where nobody will ever inspect it again. Whatever you paint over it afterwards is not what you paid for.
The plates move that work off the chassis. Mounts get welded to a removable bare steel plate on a bench, where the welding is easier to do well and easier to see, and the finished plate bolts on. The galvanising is never touched. It also means the mounting is reversible: change engines in five years and you make new plates rather than cutting the chassis about again.
This galvanised Defender chassis design gives builders complete flexibility when choosing an engine. Whether you’re fitting a Cummins, BMW M57, Mercedes Benz OM606, LS3, TD5, or another powerplant, the engine mounts can be fabricated directly onto the removable plates before simply bolting them onto the chassis.
That flexibility is the reason to order this chassis rather than a conventional one. Look down the engine list below: Cummins R2.8, Cummins 4BT, Ford Barra, Toyota 1HD, Nissan TD42. We do not make bolt in mount kits for any of those, so on a conversion like that somebody is fabricating mounts, and this chassis is designed for that to happen away from the galvanising. If your engine is a BMW M57 instead, we do sell bolt in M57 Defender mounts, and the two approaches can be combined.

Be clear about what arrives. This is a chassis with its mounting plates. There is no bulkhead, no body, no axles, no suspension, no steering, no brake lines, no fuel tank, no engine and no gearbox. It is the starting point for a rebuild, which means the rest of your project has to be either salvageable from the old vehicle or already on order.
That is a different proposition from the + 2500€ new chassis option on our conversion kits. There, we build the conversion onto a new chassis for you. Here, you are buying the chassis and doing the build. If you are not sure which of the two routes suits your project, talk it through with us before ordering either.
Two lists above decide it: the wheelbase and the chassis configuration. Confirm which of the six configurations matches the vehicle you are building, because a 200Tdi chassis and a TD4 Puma chassis are not interchangeable and the body and running gear you already own have to sit on it. If your engine is not on the compatibility list, that is not necessarily a no, it just means we should discuss it first.
