Ford Mustang T5 World Class Countershaft Rear Support Plate & Shim Kit, T5-144K
The Ford Mustang T5 World Class Countershaft Rear Support Plate and Shim Kit (Part Number: T5-144K) is a premium, high-strength billet steel upgrade engineered to reinforce the rear bearing retainer area on 1985-up BorgWarner / TREMEC T5 World Class 5-speed manual transmissions.
This heavy-duty kit replaces flimsy factory stamped steel or aluminum plates that stretch, flex, or ovalize under high-horsepower racing conditions. By securing the bearing race, it eliminates countershaft play and prevents devastating gear train misalignment.
Designed specifically for Ford Mustang T5 World Class transmission setups. Centering holes are updated for precise alignment.
Please Note: This kit will not fit Non World Class (NWC) T5 units featuring brass synchronizer rings. Due to tight tolerances and the physical thickness of fifth gear assemblies, it does NOT fit GM Chevrolet S10 or Camaro T5.
