This aftermarket hardened steel ring gear is produced for HPI Savage, Savage X and Savage XL models to replace the stock ring with a more durable tooth surface. It is intended for RC hobby use where increased abrasion and impact resistance are desired.
Fit SSAV1201 with attention to spur and pinion alignment and set the recommended backlash to maintain a smooth mesh. The item is compatible with the original gearbox layout, and checking mesh and bearings after initial runs will help identify any setup issues early.
For aggressive driving and tuning, a hardened ring gear helps maintain stable contact under higher loads and repeated shocks, but long-term success depends on correct mating gear condition and thorough setup.
A durability-focused replacement for the listed Savage models, this ring gear should be installed carefully and used alongside well-maintained spurs and bearings for best longevity.
