Product Description

Valve Spring Shims and Kits

  • Equalize installed height of valve spring
  • Engineered from the highest quality shim stock
  • Heat-treated to withstand radical camshaft lobes
  • Available in three different thicknesses to help achieve proper valve spring height
  • Shim kits contain (16) pieces of each thickness listed

Big Block Chevrolet Seat Spacers
Late model Big Block Chevrolet engines are originally equipped with exhaust valve rotators. Until now, the only way to make up for the rotator was to stack .300” of shims under the spring. This was not only sloppy, but they also didn’t fit well. These seat spacers offered by COMP Cams will locate the spring with an outside step so the spring cannot “walk” around on the head.
