47RE Transmission Stage 4 1,000HP+

Stage 4 47RE Transmission - Ultimate Race-Ready Performance

The Pinnacle of 47RE Upgrades

For those who push their Dodge Cummins to the extreme, the Stage 4 47RE Transmission is engineered to handle over 1,000 HP. Designed for the ultimate enthusiast, this transmission is built to deliver peak performance both on the track and or whatever you may do with your pickup.

Unmatched Performance and Durability

The Stage 4 47RE Transmission incorporates advanced components to ensure superior strength and reliability. It features the XHD Series Quad Disc Converter, available in Stock Stall (Tow/Daily 1800-2000 RPM) or High Stall (Street/Track 2400-2600 RPM), allowing you to choose performance based on your specific needs.

To handle the power and stress, the transmission includes Alto G3 Power Pack Clutches and Steels, a power-packed overdrive with a custom pressure plate, and a TCS Billet Direct Drum with a power pack. The TCS Super Servo, Billet Band Strut, and Billet Wedge enhance the transmission's robustness.

For increased durability, the transmission is equipped with a Billet Accumulator, a Billet 4.2 Lever, and an oversized Sonnax Billet Input Shaft. The Ridged 2nd Gear Band and Heavy Duty Direct Drum Piston further support its strength. The Borg Warner Governor Pressure Solenoid and High Pressure Transducer ensure precise control of transmission pressures, while the Heavy Duty Cast Aluminum Deep Pan improves cooling and durability. Lastly, we add PTFE Coated Thrust Washers are used to reduce friction and enhance longevity.

Incorporating a Billet Maraging Intermediate Shaft and a Big Daddy Output Shaft, the Stage 4 47RE is built to endure extreme conditions. For those seeking maximum control, the custom High Pressure Valve Body can be upgraded to the ‘Baby Mama’ High Pressure Full Manual Valve Body, which includes a billet reverse servo. 

Tested and Proven on the Track

The Stage 4 47RE is not merely a concept; it has been rigorously tested in real-world conditions. The same level of build quality is applied in our record-setting truck,  "Red Delicious," which achieved an impressive 3,180 HP at the Ultimate Callout Challenge in June 2024. Although this truck used the newer 48RE transmission, the Stage 4 47RE shares the same fundamental design and engineering.
