Break-in oil

DRIVEN DBR 15W-40 BREAK-IN OIL – 4 GALLONS.  This DIESEL SPECIFIC BREAK-IN OIL from Joe Gibbs Racing is recommended for use in our re-manufactured diesel engines.  Promotes proper surface mating during the critical break-in process and chemically assists with piston ring sealing in high-performance and turbocharged diesel engines.
* Shipped with engine with no additional shipping charges.

O-ringed cylinder heads

O-RINGED CYLINDER HEADS allow for a better head-to-block combustion seal helping to avoid the potential of blown head gaskets.

Stage 1 Camshaft

Stage 1 performance cam for the 6.6L Duramax. Featuring a moderate intake/exhaust duration, and a .470″ lift, this is an ideal camshaft to match with near stock or moderately tuned engines. With power production focused below 4000 rpm, you can expect low-mid range power increases, without sacrificing low end torque. Also, no modifications are necessary to the heads of your pistons unlike some aftermarket cams

Stage 1 Alternate Firing Order Camshaft

For trucks producing larger power numbers, or for those aware of the crankshaft failure rate at higher power production numbers, We offer an alternate firing pattern version of the Stage 1 cam. For those not familiar, as you produce high power, there are little vibrations that develop and lead to failures of the crankshaft. One remedy for this is an old hot-rodders trick, of changing the firing order. The result is a change in the location of those harmonic frequencies. With the resonant frequencies relocated, the forces and science that’s happening in all that metal are redistributed more evenly, promoting reliability and less change of failure.
NOTE:
When converting to an alternate firing order camshaft, you need to re-pin your injectors to correspond with the changes.
