Allison C-2 Clutch Hub
TCS has addressed the early failure of the C-2 clutch hub in high torque/horsepower applications with this new billet steel clutch hub.
- Made from 4140 HTSR billet steel.
- Zinc Chromate finish.
- Spline is lengthened .125" for more contact, plus a spline boss diameter increase of .100" for added strength.
- No weight penalty for strength. The TCS hub is only 2.8oz. heavier than the O.E.M. part.
- Comes with a modified thrust washer.
- Machining modification to P1 Sun Gear Required.
