Product Description

When you install stiffer valvesprings and/or a higher lift camshaft, your stock lifters are struggling to keep up. The solution to this is our lifter spring package. These lifter springs are based off the same ones found in the Gen III GM V8's also known as the LS family of engines. The piston spring (larger one) is 60% stiffer than factory, and the checkball spring is 100% stiffer. You can buy these springs separately or fully-assembled in either used stock lifters or brand new ones.
