6061 Billet Aluminum Clutch Bell Carrier, Largest Clutch Bell bearings offered by any Manufacturer. The new TR Enclosed Carrier is vented properly so it is difficult for dirt and sand to enter, but it allows heat and expansion to disperse. The TR HD-Clutch Bells are machined from Billet Steel, to ensure concentricity and the strongest bell possible. No welds to break. Turtle has drilled and tapped the TR HD-Clutch bell for a M6 Pinion Screw!! Compare that to the stock M4, you WILL NOT break pinion screws anymore! If you break a pinion screw during driving, turtle will replace the screw, bell and pinion.
