Featuring Alto G3 Clutches & Steels 

The Alto G3 line has a long-standing reputation for its strength and reliability in transmission builds. Developed to withstand extreme demands, G3 frictions have become the gold standard for builders who demand durability and consistent performance.

Recognizing the need for a tough, long-lasting transmission solution, we teamed up with Alto to bring a full clutch and steel lineup specifically designed for the 47RE & 48RE. Built with the same trusted G3 technology, this lineup offers unmatched resilience, ensuring your transmission can handle anything you throw at it—whether it’s the heavy demands of towing or the rigors of track racing.

This collaboration between Randy’s and Alto guarantees that your 48RE gets the best in performance, tested and proven under real-world conditions.

Backed by Real-World Testing and Proven Expertise

Since 2008, we have mastered the 48RE transmission. Through years of hands-on experience, we’ve fine-tuned our builds to deliver unmatched durability and performance. When it comes to the 48RE, nobody else comes close.

Our very own Red Delicious (2006 Cummins Dually) started with stock power, but out of a desire to find and eliminate every weak point, we steadily increased its power. Each stage of development allowed us to identify and address vulnerabilities, resulting in a transmission built to withstand anything you can throw at it. Our real-world testing ensures that every transmission we produce is battle-tested and ready for the road or track
