These torque spikes can easily exceed the ratings of your drivetrain components and lead to overheated transmissions, broken gears and twisted shafts. These spikes are generated by the inertia of the rotating engine components and have been measured to be 2X-4X the actual torque output of the engine. DriveGuardian reduces the torque spikes that are created each time the propeller becomes aerated or exits, and then re-enters the water after hitting a wave. Includes a 1-year Manufacturer Warranty.ĭriveGuardian SSM is a patented device that improves the reliability of your transmissions and drives. DriveGuardian NXT retains the OEM damper plate and is a direct bolt-on with no additional modifications required. The clutch plates are replaceable and the typical rebuild interval for an offshore performance application is 500-600 hours. Includes a 1-year Manufacturer Warranty.ĭriveGuardian is manufactured using billet aluminum housings and Kevlar clutch plates. ![]() Installation is a direct bolt-on with no additional modifications required. Other combinations are available upon request. Standard units are neutral balance for crankshafts with two-piece rear main seals. DriveGuardian replaces the factory flywheel and damper plate assembly and is available for either top or bottom mount starters. DriveGuardian has been proven on the racecourse with numerous National and World offshore powerboat racing Championships.ĭriveGuardian is manufactured using billet aluminum housings, Kevlar clutch plates and include a heavy duty 8-spring damper plate. DriveGuardian is a torque-limiting clutch that absorbs the damaging torque spikes and protects your entire drivetrain. While the SCS Crashbox has been proven to be nearly indestructible but these torque spikes can easily exceed the ratings of your drive and lead to broken gears and twisted shafts. Includes a 1-year Manufacturer Warranty.ĭriveGuardian SCS Crashbox, Top Mount StarterĭriveGuardian SCS is a patented device that improves the reliability of your drives. DriveGuardian replaces the stock rubber coupler and installation is a direct bolt-on with no additional modifications required. Your DriveGuardian is then calibrated for your specific engine and drive combination.ĭriveGuardian is manufactured with billet aluminum housings and Kevlar clutch plates. Prior to shipment, each DriveGuardian is mounted to a specially built dyno and load tested to ensure they meet strict manufacturing standards. Every spike causes stress to the gears and shafts which greatly reduces their usable life.ĭriveGuardian has been proven on the racecourse with numerous National and World Championships in offshore powerboat racing. Each spike lasts only a fraction of a second and throttling alone cannot eliminate them. ![]() These spikes are generated by the inertia of the rotating engine components and can be 2X-4X the actual torque output of the engine. The cause of many gear and shaft failures is the enormous torque spike that is generated each time the propeller either partially or fully leaves the water, and then is re-submerged. DriveGuardian replaces the factory Bravo rubber coupler with a multi-plate torque-limiting clutch that is calibrated to your specific application. Make sure to fill out this calibration questionnaire when ordering.ĭriveGuardian is a patented device that reduces the leading cause of pitted/broken gears and twisted shafts in Bravo sterndrives. DriveGuardian has been proven on the racecourse with numerous National and World Championships in offshore powerboat racing. These torque spikes far exceed the manufacturer’s torque rating for the NXT transmission and drive, which can lead to broken gears and twisted shafts. Heavy duty design with 8 springs and a solid backing plate that can withstand more torque than the OEM units.ĭriveGuardian NXT is a patented device that improves the reliability of your NXT transmissions and drives.
