Frequently asked questions
Is this genuine Supertech?
Yes. As an authorised Supertech dealer we supply genuine Supertech parts, new and not replicas.
How do I choose the right valve spring kit?
Match the kit to your engine and your cam lift. Stock-style cams suit single or beehive springs, while higher-lift cams need dual springs rated for the extra lift. Supertech lists spring kits by engine, and many pair with specific retainers and seats, so check the kit notes or ask us with your cam spec.
Do I need new retainers, seats or seals with the springs?
Often yes. Many Supertech dual-spring kits are designed to run with their titanium retainers and spring seats rather than the factory parts, and a head job is the right time to renew valve stem seals. We can confirm what a given kit includes.
Can you supply for my build?
Yes. Our Ringwood workshop supplies Supertech valvetrain and pistons for engine builds and head jobs, and can help match parts to your engine and target.
