Ar44 Ring and pinion 8/30

​Upgrade your competition crawler's drivetrain with the ultimate combination of strength, precision, and weight savings. Engineered specifically to handle intense binding and high-torque lines, this heavy-duty ring and pinion set delivers a massive durability boost while shaving critical rotating mass from your axles. ​By combining ultra-tough hardened chromoly steel gears with a premium titanium locker, this assembly drops total weight down to a mere 23.64 grams—making it a full 7 grams lighter than standard aftermarket options. ​Key Features ​Hardened Chromoly Steel Gears: The 8T pinion and 30T ring gear are precision-machined from premium chromoly steel and hardened to resist chipping and wear under heavy throttle. ​ Hex shape Titanium Locker: The locker features a built-in hex design that locks directly into the assembly, completely eliminating locker slippage and protecting your drivetrain. ​6-Bolt Mounting Design: Utilizes a secure 6-bolt interface between the ring gear and locker for maximum shear strength and rigid alignment. ​Unmatched Weight Savings: At just 23.64g, reducing rotating mass here means quicker throttle response and less strain on your motor and ESC.
