Description
The Redcat Racing RER42135 is a set of heavy-duty 8-tooth (8T) differential pinion gears designed for the Ascent-18 Apex platform. These pinions are the critical link between your center driveshafts and the axle gears, specifically engineered to mesh with the RER42134 20T one-piece spool. This specific gear combination is what gives the Apex its optimized gear reduction and crawling torque, making it a vital part of the vehicle’s high-performance drivetrain.
Vehicle Compatibility
This pinion set is specifically intended for the high-performance Apex axles:
-
Ascent-18 Apex (Original factory replacement)
-
Ascent-18 / Scout II (Upgrade – Must be used in conjunction with the RER42134 20T Spool; will not mesh with standard 1/18 ring gears)
Key Features
-
Optimized Gear Mesh: The 8T count is precision-machined to provide a smooth and efficient interface with the Apex-specific 20T ring gear, reducing friction and heat buildup.
-
Heavy-Duty Construction: Made from high-strength steel to withstand the extreme torque of brushless motors and 3S LiPo power systems.
-
Direct Input Connection: Designed to slide perfectly onto the axle input shafts and lock securely to the center driveshafts.
-
Twin Pack: Includes two pinions, allowing you to refresh or upgrade both the front and rear axles at the same time for consistent drivetrain performance.
