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.

Modification Required:
- For it to be “drop in” on a 12valve, you will need no more than .020″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline. . If you do not meet the minimum requirements for piston to valve clearance, don’t worry, you can still run an oversize head gasket or cut valve reliefs.
- Although this is considered a drop in cam it is important to check clearances
Break in:
To make sure that you have no issues during break-in, follow these few suggestions.
- Make sure that the cam has a Liberal amount of quality assembly lube applied
- DO NOT let the engine start without oil pressure
- When this is a new engine, be sure to put a liberal amount of assembly lube in the oil pump and prime the oil filter
- Be sure to change the oil after you have done your break-in procedure. When the filter and oil system are already primed, engine will get oil pressure much faster than if the oil is changed at the same time.
- Disconnect the fuel system and spin the engine with the starter until oil pressure can be read or until oil is coming out of the rocker arms.
- Once oil pressure has been verified, let the engine start and run for five minutes at 1200-1500rpm then shut engine down
- Adjust valves then you are cleared to abuse your engine. Enjoy the added airflow
- if you need to re-torque or “hot-torque “the head, do so before adjusting valves. Re-torqueing the head changes the valve lash setting, so it is important to set lash last.
