Extreme Duty Billet Overdrive Clutch Drum Assembly for 68-RFE, 545-RFE, 65-RFE and 66-RFE Transmission. This OD/UD drum requires assembly. Single sided clutch/steel plates in UD sedtion and extreme duty Koline clutch plates and GPZ clutch plates in the OD clutch pack.

RFE Transmissions pulling heavy loads or boosted to 600+HP are at high risk for overdrive burn up due to the stock transmission's insufficient clutch capacity and fragile OE clutches.

Even small amounts of heat and extra torque will push the thin (.034 inch), single-sided clutches over the edge, distorting the clutch pack. The fact is, any distortion of the clutch pack takes the clearance out of spec and makes overdrive clutch burn up inevitable.

Keep hardworking trucks on the road with this Extreme Duty overdrive clutch housing kit 314-505-2326. The unique billet aluminum housing holds a physically taller clutch pack and increases OD apply area by 16 percent. Plus, 2X thicker clutches increase clutch pack steel mass by 28 percent for unrivaled heat dissipation.

This groundbreaking kit is the only top-of-the-line upgrade that eliminates clutch problems without relying solely on valve body and pump modifications.
