The THUNDER TIGER K-ROCK MT4 Spring Steel Differential Bevel Gears by GPM KG1043TS are specified to provide consistent tooth form and reliable load sharing in the differential. Spring steel materiality is selected for fatigue resistance and dimensional stability under repeated torque cycles.
These gears deliver consistent engagement thanks to controlled manufacturing tolerances and the spiral bevel geometry, which promotes smoother torque transmission and reduced impact loading on adjacent drivetrain components.
As a direct-fit replacement, this set improves power transfer characteristics while maintaining serviceability and ease of installation for workshop upgrades and maintenance cycles.
