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.
