PacBrake 60lbs 12V Valve Springs PacBrake 60lbs 12V Valve Springs

  • SOLD IN SETS OF 6.
  • THESE ARE SAFE TO TURN 4000RPM
PacBrake strongly recommends installing heavy duty (60 psi) exhaust valve springs with their exhaust brake on 1988-1998 12 valve Dodge Cummins for optimum braking power. The factory exhaust valve springs are not rated to retain the pressure the PacBrake puts forth on the springs.

Can be used on the intake side or the exhaust side. Only six (6) are required for the exhaust valves if you're installing an engine brake. Twelve for both the intake and exhaust if your goal is performance related.

The seat pressure on these springs is ~115lbs at the installed height of 1.950. At 400 lift, the spring pressure is ~192-195lbs. At 500 lift, the spring pressure is ~210lbs.
