AXIAL Racing SMT10 Hard Steel Differential Gear Set by GPM SMJ1202  [SMJ1202]

Hard Steel Differential Gear Set

This GPM SMJ1202 hard steel gear set is designed for the AXIAL Racing SMT10 differential assembly and supplied as a 2pcs set. The hardened steel construction targets increased wear resistance compared with typical stock gears, helping maintain consistent gear mesh under higher loads encountered during trail and competition-style RC driving.

Installation is straightforward for builders familiar with SMT10 differentials: replace the stock differential gears inside the diff case, verify gear mesh and backlash, and confirm smooth rotation of the differential with the original bearings and shims in place. No special tools are added with the product, so use your existing differential disassembly tools and a clean workspace to avoid contamination.

In tuning terms, upgraded steel gears focus on durability and stable power transfer rather than changing gear ratios; they are best used when stock gears show wear or when higher torque from motor and gearing setups demands tougher internals. Regular inspection for wear and correct lubrication will keep engagement smooth and parts lasting longer.

Use this gear set when upgrading internal diff durability on SMT10 models or as part of a reliability-focused build where gear longevity is a priority.
