BTR SPRING KIT – SOLID ROLLER LSx – .750″ LIFT – SK427
When you take the plunge into a solid roller combination, taking the guesswork out of the valvetrain combination is a huge relief. For that reason, BTR is proud to introduce the SK427 valve spring kit. It is comprised of our all-new SR532 titanium retainers, PSI427RML Springs, complete valve seal kit, and our tried and true locator options. You have the ability to purchase these with either .505″/.060″ locators (standard guides) or the .565″/.60″ locators (most bronze guide applications).
NOTE: Please check valve guide clearance if you exceed .650 – .660 lift.
