Selection and compatibility guide
Compare ratio, gearbox version, material, and complete-build requirements before choosing a gear set. The best result comes from matching the gears to the motor, spring, battery, shell, and installation plan.
Compare the available ratio with the target balance of cycle speed, trigger response, and torque.
Confirm V2, V3, SR25, DSG, sector-gear, and piston requirements in the individual listing.
Motor, spring, battery, shell, bearings or bushings, shimming, and installation all affect the result.
13:1 is commonly selected for faster cycling, while 18:1 is a conventional ratio often used in general-purpose builds. The final result still depends on the motor, spring, battery, gearbox condition, and installation.
No assumption should be made from the category alone. Confirm the compatibility statement, selected variant, sector-gear configuration, and complete product specification before ordering.
