Rebuild Kit Made For Improving Torque and Performance

The SunCoast Category 68RFE transmission rebuild kits are designed and developed with intentions of taking a systematic approach to solving the issues with the 68RFE transmission. We approach each deficiency and need with careful consideration. These kits offer you the same recipes that are used in our facility when we build these units. We aim to offer you the most complete series of 68RFE rebuild kits available on the market today with proven combinations for a successful build. The factory overdrive clutches are at a high risk of failure when towing or installing aftermarket programmers, delete kits, or larger turbos. When exposed to increased torque or higher temperatures, the factory drum will distort, causing additional clearance and uneven apply. This will always result in burnt clutches. These clutches in the overdrive housing are, by far, the weakest link in the 68RFE transmission design.

Improves Horsepower With High-Quality Components

The V2 68RFE Billet drum is the most revolutionary thing that has happened to the 68RFE. There has been no other project here that we have invested as much research and development in. We have had over 1,000 horsepower on this drum. This is the end-all, be-all of the 68RFE drums, correcting the issues plaguing the overdrive circuit without the annoying squawk that is so common in the 68RFE. This new 68RFE overdrive billet drum boasts a whopping 24% clamping force over the factory drum, improving apply time and reducing slip engagement dramatically. This new V2 drum also incorporates a newly designed Quad Ring that allows ideal stretch and compression during higher RPM operation to ensure a consistent clutch volume index throughout the life of the transmission.
