The SC-100™ and SC-150™ are the two LSM on the engine valve spring compressors for wedge/inline style engines with shaft mounted rockers that come off in pairs joined on one common shaft. With the SC-100/150™ Combo you will receive the complete SC-100™ tool plus the SC-150™ Base. Use the SC-100™ on your smaller centerline needs so you don't have clearance issues, and swap out bases when you have wider mounting needs.
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. The SC-150™ slotted aluminum base accommodates 5/16" bolts or studs with 3.20" - 4.00" for the two outside bolts/studs center line spacing. Remove your pair of rockers and bolt the tool right to the stand. If you have a center stud, the base has a clearance slot, but does not require a nut for mounting. Tool slides back and forth from intake to exhaust to compress and change springs.
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.
