LSM SC-320™ on head valve spring compressor for Big Block Mopar using a single bar shaft system. Rocker system where all the rockers come off at once, held down by five bolts or studs, such as on 440-1 Indy Heads. Makes changing valve springs an easy, one-person job. Mounts in front of each pair of rockers and slides back and forth between intake and exhaust. Works great with our SH-60™ Speed Handle. 

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!
