GPM CRA155817T precision gear upgrade for Traxxas Craniac

This GPM kit replaces the stock spur assembly on the Traxxas Craniac Monster Truck with an aluminium spur gear adapter and hardened steel 58T and 17T gears. The parts are intended to reduce deformation under load and maintain stable mesh in aggressive driving conditions.

Technical Highlights

Material: Machined aluminium adapter paired with hardened steel gears to improve wear resistance
Compatibility: Engineered to match Traxxas Craniac mounting dimensions for direct replacement
Performance: Improved torque transmission and reduced deformation compared to stock plastic components
Installation: Precision fit designed to minimise setup time and maintain correct gear alignment

Packing includes

Aluminum Spur Gear Adapter
Steel Gear 58T
Steel Gear 17T

What maintenance does the GPM CRA155817T require under race use?

Inspect gear teeth and bearing surfaces after high stress sessions. Remove metal debris, check for fretting at spline interfaces, and reapply light synthetic gear grease. Replace components showing stress cracks or significant tooth wear.

Are any shims or spacers recommended for optimal mesh?

The adapter is dimensioned for direct fitment, but minor shim adjustments can fine tune mesh on cars with aftermarket pinions. Measure backlash and use thin shims to achieve 0.1 to 0.2 mm clearance under static conditions.

How does this upgrade affect drivetrain longevity under heavy use?

Switching plastic components to aluminium and hardened steel shifts failure modes to bearing or shaft stress rather than gear tooth deformation, generally increasing service intervals when properly maintained.
