If you already have our LSM SC-150 valve spring compressor, you can swap out the base if you need the shorter SC-100™ footprint. Just remove the bolts that hold the base and shaft together and replace with the new base. It's that simple. 

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.

*This item is only for the base and shaft as shown. 

**If you have an older, "vintage" SC-100 or SC-150 LSM valve spring compressor with a press-fit shaft to hold on the base, you will need the SC-100 Beam and Base combination.
