ARRMA Kraton 1/5 20CrMnTi steel center differential gear set 53T/19T M1.0 by GPM MAKX1953TS  [MAKX1953TS]

Center differential gear set for ARRMA Kraton

This GPM MAKX1953TS gear set is a direct-fit center differential upgrade for ARRMA Kraton 1/5 scale vehicles, supplied as a matched pair of a 53T center diff gear and a 19T idler gear in 1.0 module. Machined from 20CrMnTi steel, the pair replaces the factory center diff components ARA310919 and ARA310921 to provide higher wear resistance under heavy 8S brushless loads while retaining the original tooth profile and module size.

Fit and function are focused on RC-scale drivetrain use only. The gears are intended for installation into the vehicle’s center differential housing and should be checked for correct mesh and bearing fit during assembly. Because the set keeps the stock M1.0 pitch and tooth counts, it maintains compatibility with the Kraton gearbox geometry and pinion/spur ratios specified by ARRMA for the listed models.

Practical notes: verify differential bearing clearance and clean mating surfaces before installation, confirm that the idler locates correctly on its shaft, and recheck gear mesh after a short bedding run. The steel material reduces deformation and pitting risk compared with softer alloys, which can help with consistency in high-torque, high-RPM 8S brushless setups.

Use this steel gear set where increased durability and resistance to wear are priorities, particularly in high-power 8S brushless Kraton builds that demand consistent center diff behavior under load.
