Build Your 68RFE the Right Way

The BD Diesel 1062035 Big Stack Overdrive Shaft & Reaction Plates Kit is engineered for performance builders who want to reinforce their 68RFE transmission using the same components found in BD’s top-tier builds. With a redesigned overdrive clutch stack featuring 16 friction surfaces, this kit dramatically increases the transmission's torque capacity and heat handling—especially under towing or high-load conditions.

Billet QT100 reaction plates improve clutch face integrity and minimize distortion under pressure. This kit pairs best with Raybestos clutch frictions (B29308L / B29309L), which are included in BD's full Build-It kits for complete transmission rebuilds.
