Pairs well with
High-performance friction material and precision-manufactured steel discs.
Separator springs added to the hard-working C&E clutches minimize hub chatter, especially when paired with our hard anodized hubs. These springs reduce drag and improve crossover performance, eliminating the usual downsides associated with increased plate counts such as jerky behavior, multiple learning attempts, or chattery take-off performance.
Our patent-pending steel-core splined hub design with aluminum outer provides all the strength of a steel hub without the transmission-upsetting inertia. The hard anodized outers are chatter-resistant and have additional oiling holes to optimize oil flow, ensuring optimal temperature control of the denser clutch stacks.
The C Hub included featuring aerospace grade billet aluminum, hard anodized to minimize wear and enhanced oiling passages.
Promax also includes additional frictions and steels over the sportsman’s plus with billet end plates and upgraded billet pistons.
Clutch A – 8 Plates (+3)
Clutch B – 7 Plates (+2)
Clutch C – 12 Plates (+6)
Clutch D – 8 Plates (+4)
Clutch E – 11 Plates (+6)
Promax over 1700 hp

FAQ
Fitment is confirmed for the applications listed in the Specs section above. Always confirm final fitment by year, market, and supporting hardware before ordering.
Yes. A professional calibration is required to safely control boost, fueling, torque limits, and thermal management.
Fueling, charge-air cooling, intake flow, downpipes, and drivetrain upgrades may be required depending on target power and fuel type.
The system is engineered for strong response, but daily drivability depends on calibration, fuel quality, supporting parts, and installation quality.
Warranty coverage applies to manufacturing defects under normal installation and operating conditions. Track use and improper calibration may affect coverage.
