LSM LS1/LS7 Spring Compressor SC-125

Heavy Duty “On Head” valve spring compressor for the GM LS1/LS7 Factory GM Rocker Bar valvetrain.

All LSM on head Valve Spring Compressors have a tapered flange retainer housing that can fit springs as small as .800″ and up to 1.600″. And they can easily and safely handle 1,000 pounds of seat pressure with our screw down method that will not spin back. Plus, you won’t need an extra set of hands so you don’t lose your keepers. No need to take off the pedestals – our compressors bolt right to the stands!

Note: if you don’t see your combination listed, contact us and we’ll find the right spring compressor for you.
