ETP has been developting our own range of spring kits over the last three years. Not many people know we do them. They are a great inexspensive option to get build up a cylinder head order, without the need to wait for an exchange core to be sent back.
Plus there is a reductions labour costs in stripping the old head of parts. All the parts are conviently sealed up in seperate bags, reducing the risk of loosing parts and slowing up the job.
Our newest spring kit, that we're promoting on our facebook page, is for the Toyota 1FZ engine.
We also stock spring kits for:
Mitsubishi 4G64 and 63
We have a number of new kits in developement that will be ready soon.
