Hamilton Cams 07-C-002 Bolt On Cam Retainer 89-02 5.9L Cummins

For use with mechanically injected engines with helical cut cam gears. The bolt on retainer will ensure that the cam gear is not pushed off of the cam in high rpm, high fuel delivery situations.

Common rail engines or engines that use straight cut or spur gears do not need this bolt on retainer.
