Project Carbon® 10L1000 Billet “E” Apply Piston + Balance Piston Combo

Project Carbon® 10L1000 Billet “E” Apply Piston + Balance Piston Combo:

    Known for cracking and flexing, the Project Carbon Billet 6061 “E” Apply Piston + Balance Piston combo are the most durable upgrades available for these problematic components and are a necessity for long-term reliability. 

     Further, when paired with aftermarket “E” hubs that feature taller splines, the apply piston can be safely machined down to add additional clutches with zero risk of deflection. This critical upgrade is standard in ALL Next Gen Drivetrain Allison 10L1000 transmissions.

     Best of all, these pieces use the factory D-Ring seals, springs and snap rings for ease of install and use. Lastly, these 100% American-made billet pistons are totally solid with no weight-reducing unnecessary cuts that detract from reliability in demanding applications.
