PSI High Lift Valve Springs
High lift valve springs for all LS & LT engines.
This beehive spring is Katech’s default for all engine packages with heavier valves. Optron valvetrain dynamics testing revealed this spring was the best choice to keep heavier replacement valves in control.
Works with LS, LT1,L83 & LT4 with proper hardware.
