Description

The SunCoast 68-LRS 68RFE Upgraded L/R Sprag is a Patent-Pending Billet M3GA Sprag designed to reinforce your 68RFE transmission. It addresses the common failure of the factory "dogbone" sprag under stress, preventing flipping and ensuring reliable power transfer. This billet, precision-machined upgrade features a redesigned spring style for consistent pre-load tension, making it suitable for high-horsepower 6.7L Cummins trucks.
