Cam retainers are NOT to be used with 2003+ 5.9L & 6.7L Cummins engines unless your front cover has been modified for proper clearance.
Cams generally ship in 2-3 business days. If you are in a hurry, please call us to check availability.
Tappets MUST be purchased from us at the time of the cam purchase or your warranty is void.
These tappets are brand new Cummins tappets that have been ground with a performance profile for better tappet rotation and wear.
If you'd like, you may send your lifters in to be re-surfaced by No Limit Mfg. This costs approximately $100.
No Limit part number: CMN003031
