LSM Racing SC-100 Valve Spring Compressor Tool

The SC-100™ is our on the engine valve spring compressor for wedge/inline style engines with shaft mounted rockers that come off in pairs joined on one common shaft. 

The SC-100™ slotted aluminum base accommodates 5/16" bolts or studs with 3.20" - 3.60" for the two outside bolts/studs center line spacing. (For wider spacing see the SC-150™.) If you have a center stud, the base has a clearance slot, but does not require a nut for mounting. Remove pair of rockers and bolt the SC-100™ right to the stand. Tool slides back and forth from intake to exhaust to compress.

All LSM on head valve spring compressors have a tapered flange retainer housing that can fit springs as small as 0.800" 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!

Don't forget your optional SH-60™ Speed Handle. 

You can also purchase just the SC-150™ Base to interchange with your SC-100™ to have the opportunity to use on wider center line situations. Find it under LSM Upgrade Parts under Shop. Or we have the SC-100/150™ Combo.
