    Will It Fit Your Vehicle?

    This is a universal k-series part. Vehicle specific fitment cannot be guaranteed. Please read the product description and details prior to purchase.


    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+.
