1x Full set of 8 Carrillo Pro-H 9321 Connecting Rods

(Part# GM_B66DM_0HS_6418B7H)

​Rated up to 1800HP

The Carrillo 6.6L Duramax Pro-H Connecting Rod With H-11 Bolts is a must have in your 2001-2010 GM 6.6L Duramax engine build. Since 1963, Carrillo is recognized as the preeminent custom connecting rod manufacturer in the world. Carrillo has provided custom and prototype connecting rods to virtually every major automotive and motorcycle venue, most notably to the high performance and speed equipment industry.  

Carrillo uses proprietary chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). The heat is validated, both by the supplier and an independent metallurgist whom confirm the desired physical and chemical properties of steel.  All heat treat processes are via a mar-aged operation, resulting in UTS of 195,000 with a yield of 182,000 while maintaining the critical elements of low notch-sensitivity and ductility.  

All Carrillo connecting rods are manufactured from an oversized forging resulting in the proper grainflow as well as the surface removal of any potential inclusions or surface conversions generated by the forging process. All critical CNC machines at Carrillo are equipped with probing to accurately validate dimensional integrity. In the production process each part is magnafluxed at least twice, further each piece is Rockwell tested to validate the heat treat procedure. A final shotpeen operation completes the part. This connecting rod comes with H-11 bolts and is for use in a wide range of applications. 

1x Full set of 8 Mahle Motorsports Performance Cast Piston Kit

​Rated up to 1000HP

Designed for street/strip or pulling trucks making 400-1000HP that still get used as a daily driver or work truck. Machined from OE castings (retaining the cast iron ring insert) to give the same drivability and longevity of a replacement piston with additional strength necessary for modified engines. These Pistons are built for customers looking to get 100,000+ miles on a high horsepower application. Unlike some of the higher HP forged pistons which need to be replaced every 20,000 to 30,000 miles, these Mahle Pistons are built to last.

1x ATI Super Damper

(Part# 917369) 

Free up some horsepower while prolonging your diesel’s crankshaft life.Keep damaging crank harmonics away. ATI Super Harmonic Dampers are proven to be 30 percent more effective than stock dampers. That means a smoother running engine with improved power output—up to 12 more horsepower. ATI Super Harmonic Dampers are also re-buildable and tunable by replacing, removing, and adjusting the elastomer strips. And, since the damper bolts right to the crank hub, the timing marks are always in the same spot. So, when the marks start to move, you know it’s time to replace the elastomer strips.

(Part# SD-BILLET-FLEX)

Billet 1 Piece Flexplates are lighter and stronger than stock

They Meet the new SFI 29.3 specification for competition use

1x Billet Main Girdle

​The Duramax engine suffers from main cap movement at high power levels. Even with ARP main studs and cross bolts, we have seen evidence in the bearing wear, of the cap flexing towards the front or the rear of the engine. This Billet Main Girdle is a solution that provides structure to the top of the main caps, linking all of the main caps together, as well as linking the main caps to the pan rail.
