AXIAL Capra 1.9 UNLIMITED Front and Rear Gearbox Cover Upgrade - CP012A by GPM  [CP012A]

Aluminium gearbox covers for Capra driveboxes

This aluminium gearbox cover set replaces the original plastic caps on the AXIAL Capra 1.9 UNLIMITED front and rear units to provide a firmer mounting point for the differential assembly. The upgrade is aimed at scale RC use and helps keep differential alignment under torque, which can cut slop and produce steadier drivetrain behaviour during slow technical crawling.

The plates sit over the gearbox opening and are clamped down with the supplied stainless steel cap head screws to secure the diff housing. Machined from aluminium 6061 T6, the plates broaden the bearing support area and resist deformation better than stock plastic caps, so the diff carrier retains its position more consistently when tuned for tighter lash or when running heavier gear ratios.

Installation is straightforward for those experienced with drivetrain maintenance: remove the OEM cover, place the aluminium plate over the opening, and tighten the supplied screws to the correct torque. After fitting, check the differential preload and bearing alignment because the stiffer mount may change backlash and engagement feel.

A reliable, serviceable upgrade for AXIAL Capra 1.9 owners seeking reduced gearbox flex and improved differential consistency without altering normal servicing routines.
