This kit upgrades every part of the 12v valvetrain . When you combine our best all-around performing camshaft, with valve springs that control the valvetrain to 4500rpm and 80lbs of boost, pushrods that are rated to well over 2,000hp and our 1.45″ tappets that provide more surface area, you have the best cam combo on the market for the 1989-1998 dodge Cummins.
If you’re looking for the quickest spool and the widest rpm band of all of our cams, this is it. Initially designed for trucks that work hard and need instant torque in the low rpm range. It was later found to greatly help spool large single turbos, increase fuel economy, lower EGT, maintain power at higher elevations, all while keeping big hp and rpm potential. It is also 49 state EPA compliant. If you are thinking it is too small for your hp goals, think again. On our engine dyno, a 6.7l with a single s400 it made 1100hp with a stock head, 1250 on a stock head with larger valves, and 1588hp @4500 RPM with a ported head.
