Practical aluminium rear gearbox by JAZRIDER

The JAZRIDER JR-THS13-GU aluminium rear gearbox is a pragmatic replacement housing for Tamiya Hotshot, Super Hotshot, Boomerang and Bigwig models. It focuses on delivering a robust, low maintenance upgrade that integrates with common Tamiya mounting points.

Durability and everyday usability

Constructed from aluminium, this gearbox housing resists common failure modes encountered with plastic units, such as cracking and flex. It is suited to hobbyists seeking a long lasting, serviceable solution for routine driving and light bashing.

Fitment and service considerations

The housing is designed to accept standard gears and bearings used in the original assemblies. During installation, ensure correct gear mesh and that fasteners are torqued evenly. Check periodic wear points and lubricate gears as part of normal upkeep.

Practical tips for hobbyists

Retain original hardware where compatible, inspect bearings before reuse and use mild cleaning agents to preserve the finish. This approach keeps maintenance straightforward while extending part life.

Most stock internal gears and bearings fit directly. Verify bearing condition and replace if any roughness or play is detected before assembly.
Set the pinion and spur to a light contact pattern by using paper or feeler method, then secure the gearbox and rotate the drivetrain by hand to confirm smooth engagement.
Use a small drop of medium strength threadlock on steel screws to prevent loosening from vibration. Avoid heavy threadlock which can make later service difficult.
