68RFE 550HP rated.

This is our #1 seller! I set it up to hold a max effort tune and turbo upgrade on stock fuel in your 6.7 Cummins but still shift great! the official rating is 550whp, it has a billet dual disk converter, billet input shaft, heavy duty clutches, extra OD clutches and a Tow Pro valve body, deep transmission pan and all of the common failure points addressed. This is the ultimate budget minded transmission for a daily or tow truck but can take some abuse when you feel like beating on it! 

NOTE•  This unit requires a 225psi line pressure tune from a reputable source, we can also provide this service in house.

2 year 36k mile warranty.
