Technical ring gear for UDR driveline

The UDR1200S/G1 ring is a precision-engineered replacement intended for the TRAXXAS UNLIMITED DESERT RACER drivetrain. It locates within the front or rear gearbox to transmit torque from the bevel pinions into the differential carrier with improved stability.

Manufactured from hardened steel #45, the component offers enhanced wear resistance relative to standard steel gears. The combination of a harder material and tighter manufacturing tolerances is aimed at reducing backlash and delivering a more consistent gear mesh under load.

Specified for direct replacement or as part of drivetrain tuning to increase durability and engagement, verify tooth count and dimensional fit prior to installation. After assembly, set differential backlash and confirm mesh to prevent premature wear and ensure reliable operation.

Packing includes

  • Ring Gear - 1pcs
  • Stainless Steel Flat Head Screw 2.5x8 - 4pcs

Specifications

  • Item: Differential ring gear set, 5pcs total
  • Material: Hardened steel #45
  • Model Number: GPM UDR1200S/G1
  • Compatibility: TRAXXAS UNLIMITED DESERT RACER

A technically focused scale replacement intended to improve engagement and service life in the TRAXXAS UDR gearboxes; perform careful fit and mesh checks during installation to achieve the intended durability gains.

Is this ring gear compatible with both front and rear UDR gearboxes?

The part is designed for the ring gear position in either gearbox. Compatibility requires matching tooth count and profile; inspect these dimensions against the existing gear before fitting.

What hardware and pieces are supplied?

Supplied items are listed in the packing section: one ring gear and four stainless steel flat head screws 2.5x8, totalling five pieces for installation.

How does hardened steel #45 affect long term wear?

Hardened steel #45 provides higher surface hardness which reduces abrasive wear on mating teeth, helping preserve accurate gear clearance and mesh under repeated load cycles.

Recommended assembly checks for service life?

After installation, set a measured backlash, assemble the gearbox and verify smooth rotation without binding. Reassess mesh after initial running to confirm correct engagement and minimise premature wear.
