Technical notes for UDR rear differential

Engineered as a direct replacement for the TRAXXAS Unlimited Desert Racer rear differential case, this ring and pinion set is manufactured from hardened steel #45 to provide consistent wear resistance under gearbox load. The kit is presented as a 6pcs assembly intended for rear differential installation.

Parts are finished to reduce gear clearance and promote steady tooth engagement for predictable torque transfer in typical RC operation. The set contains the ring gear, pinion gear, and the flat head screws required to secure the components in the rear differential housing.

Installation guidance: verify and set gear mesh and axial play within the vehicle maker's tolerances, inspect bearings and replace if necessary, and apply the recommended torque to the mounting screws. Proper setup ensures the hardened steel gears maintain consistent contact and service life without specifying unverified performance claims.

A precision-focused, direct-fit hardened steel ring and pinion replacement for the UDR rear differential case, supplied with mounting hardware for installation.

How should backlash be set?

Set backlash to the vehicle manufacturer's recommended range and confirm smooth rotation under load before final assembly to avoid premature wear.

Are special tools required?

Standard diff assembly tools are sufficient; use accurate torque tools for the mounting screws and a feeler gauge or dial indicator to check mesh if available.

When should bearings be replaced?

Inspect bearings for play and roughness during installation; replace any bearings showing wear to preserve gear alignment and load distribution.

What maintenance is recommended?

Regularly check mesh, re-torque fasteners after initial running, and inspect for wear after heavy use to maintain reliable drivetrain operation.
