68RFE Formula One Sprag

Next Gen Diesel

Replace the failure prone low / reverse sprag in your 68RFE transmission with this much stronger roller clutch. This is the main weak point in the 68RFE transmission. If you have a performance engine and tow heavy loads this is the part you need. The 68RFE low and reverse clutch is only on when the output shaft speed is below 150 RPM. So when your doing hard accelerations or burnouts and the driveshaft speed reaches 150 the clutch releases and drops back on the low and reverse sprag. The OEM type sprag will not tolerate this too many times before it will flip the drive dogs. Result is no 1st gear and 2nd gear starts.
