COMP Cams® .450” Lift Ovate Wire Valve Spring Kit for Jeep 4.0L 1988-06 Applications

COMP Cams® introduces a .450" lift valve spring kit for Jeep 4.0L engines that allows for increased performance and reliability with minimal effort.

The Ovate Wire Valve Spring Kit for Jeep 4.0L 1988-06 Applications supports the installation of up to .450″ lift high performance cams with properly engineered valve springs that handle harmful dynamic valve train stress more efficiently, resulting in greater RPM potential and durability. The spring upgrade also eliminates valve float issues associated with the stock valve springs.

The kit includes the COMP Cams® Part #983 Ovate Wire Valve Spring and #516 valve seals while making use of your stock retainers. Ovate wire springs are constructed from oval shaped wire as opposed to round and have more material occupying the same area than round wire springs to more efficiently distribute the operation stresses.

This kit is ideal for any engine level – stock type rebuilds to high performance builds.*

*All applications must cut down the spring seat step diameter from .938” to under .830”.
