Stage 2 68RFE (750 HP)

A 750 Wheel HP 68RFE for a truck making real power that still has to work.

The Stage 2 is where the build goes past valve bodies and clutch counts into the rotating assembly. Billet input shaft, Sonnax Smart-Tech drum with our own clutch stack-up, 16-clutch-face overdrive, in-house valve body on a billet channel plate.

You need a Stage 2, not a Stage 1, if any of these apply:

37" tires, particularly without regearing (regearing still recommended)
An aftermarket turbo
Extremely heavy towing — hotshot work and similar

Big tunes, compound or large single turbos, frequent hard pulls. It can be driven every day and it will shift firmer than the lower tiers, but this is not a race-only transmission.

Fits 2007.5–2024 Ram 2500 and Ram 3500, 2WD and 4WD.

D&P ANY Stall option available

19SS — stock stall, fast to come up, couples well. Daily driving, or larger turbos needing RPM to spool.

15LC — couples very efficiently as speed ratio increases, in a lower RPM range than stock. Daily driving with moderate towing, or a light tune with a larger single turbo.

15SS — tighter stall, maximises low-RPM pulling power, keeps temperatures down. Towing and hard work.

14B — couples and tows extremely well with minimal RPM drop at lock-up, taking full advantage of the 6.7L Cummins' low-end power. Uses an indestructible billet stator guaranteed never to break. Built for trucks that spend their life under a load.

Stall depends on what your engine makes, so call if you want help matching one to your combination.
