CPP 115# VALVE SPRINGS 24V (98.5-2013 CUMMINS)

We have hit 6000-6400rpm with these springs numerous times now (with billet retainers) at over 100psi and never had one break or any float issues. You can run a higher lift cam too as these have an extra almost ¼” of travel before coil bind. On stock retainers, these are safe to turn 4500rpm without issues. We recommend retainers for 4500rpm-up.

SPECS: Ovate wire. 115# Seat, 1.360" Install Height, @.800" @ 230#, Coil Binds @ .765"
