How it works
Four steps, and an engineer on the other end of every one of them.
Tell us the platform, the gearbox you want to run and how the vehicle is used. An engineer checks the fitment — bellhousing, transfer case, driveline and loom — and confirms which kit suits your build before you spend anything.
Talk to an engineerOrder online and pay securely by card through Stripe, or ask us for a proforma invoice and pay by bank transfer. VAT is handled for your destination and shipping is quoted for your address before you commit.
Browse all kitsComponents held in stock ship straight away. Complete kits and mounted powertrains are built to order in our own workshop — we confirm the lead time when the order is placed and send photographs as your build comes together.
Shipping and deliveryEvery kit ships with our step-by-step installation video and printed documentation. If something does not match what you see on the vehicle, you can reach the engineers who built your kit directly.
Ask the workshopBuilt for expedition
We design and manufacture conversion kits that bring modern performance and reliability to classic platforms. Every kit is developed in house, tested in real conditions, and built to a standard we would put under our own vehicles.
