  • Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

About this product

Precision CNC housing for BBX BB-01

Engineered as an aftermarket upgrade, this transmission housing is specified for the TAMIYA 1/10 BBX BB-01 chassis and designated BBX038. Fabricated from 7075-T6 aluminium and CNC finished, the housing reduces internal clearance to improve spur and pinion coaxial alignment and minimise lateral endplay under torque.

The rigid aluminium shell increases gearbox stiffness and stabilises gear positioning during dynamic loads, which helps preserve consistent drive engagement and predictable steering response. This part is intended for hobbyist RC systems only.

Installation follows BB-01 service norms: remove the original housing, transfer precision bearings and internal components as needed, mount the CNC housing, and secure with factory fasteners. Perform final gear mesh and endplay verification and adjust shims or mesh before completing assembly to ensure correct backlash and tooth contact pattern.

Packing includes

  • Transmission housing set – 1pcs

Compatible Models

  • TAMIYA-1/10 BBX BB-01 CHASSIS-58719

For precision-minded hobbyists and racers, this CNC machined 7075-T6 housing offers improved gearbox stability, reduced play and reliable fitment when installed and set up correctly.

What tolerances should I expect from this CNC housing?

Manufactured to tight CNC tolerances to reduce internal clearance; final dimensional checks should confirm correct bearing bores and alignment prior to assembly.

Are any spacers or shims supplied for mesh adjustment?

No additional shims are supplied. Use the original spacing and perform mesh adjustments with standard practices to achieve the correct tooth contact pattern.

Which bearings are compatible with this housing?

The housing accepts the same bearing sizes as the OEM BB-01 housing. Transfer bearings from the stock unit or use replacements with identical dimensions for fitment. Write Product Review Please sign in your account before you can write any review.
