    Will It Fit Your Vehicle?

    This should fit your vehicle as long as you have a k-series engine.


    PSI Pro Stock Motorcycle spring with Max Life Treatment and our own custom seat and retainer. This is a lightweight package with plenty of room to run large camshafts beyond .650 lift. 132lbs on the seat, 320lbs @ .600. Package comes with springs, spring seats, and titanium retainers. These have been proven year after year and have a VERY long service life, 20 times that of the cheaper alternatives on the marke. Excellent protection against floating valves in the event of a missed gear. Max RPM 11,000+.
