Description: This tappet set from Colt Cams is a great fit for 1989 - 2018 Dodge/RAM vehicles with 5.9L or 6.7L Cummins engines. What sets it apart is its unique crown (convex surface), a key feature that guarantees rotation on the 5.9L Cummins. In the past few years, Colt Cams found big inconsistencies in crowns, with some new tappets needing crowns added, and even some being flat or dished, which is unacceptable. After studying the lobe width, they decided the 24V 2nd Generation diameter was perfect and maximized the crown for the best rotation. Part Number: CC - Tappets. Features: The unique crown ensures rotation on the 5.9L Cummins. It uses the ideal 24V 2nd Gen diameter. The crown is maximized for optimal rotation. It's made from the same metal as the camshaft cores, ensuring proper metal compatibility. Notes: Contrary to web rumors, C.R. lifters do not change timing.
