68RFE stage 3

68RFE Street Sweeper Transmission

The Street Sweeper 68RFE is designed exactly how it sounds—built for trucks that are driven daily but abused on the weekends. Developed with the perfect balance of street manners and race-inspired durability, this transmission is ideal for owners who want to turn it up without giving up drivability.

The Street Sweeper is capable of handling a wide range of performance upgrades, including injector upgrades, second-gen swaps, aggressive tuning, and spirited street use, while still remaining reliable for daily operation. This unit bridges the gap between a mild build and a full competition transmission.

Transmission tuning is required to ensure proper operation, clutch life, and long-term reliability.
