TB-05 Alu. Diff Housing Set, chassis accessory

The TB-05 Alu. Diff Housing Set upgrades the differential section of compatible TB and TB Evo chassis cars with 2 aluminum 40T housing parts, replacing the standard resin components with a more rigid assembly. That higher rigidity supports smoother, more stable running, especially when the differential is shimmed precisely and the internal parts are seated cleanly inside the housing. The set contains Housing A, Housing B, 1 gasket and 8 screws in 2x5 mm size, concentrating the change on the differential case rather than the rest of the drivetrain. Aluminum also helps minimize heating of the internal oil during running, which supports steadier differential action as sessions continue. The housing shape is designed for the TB platform family named in the compatibility list, so the upgrade stays closely matched to the original chassis layout. As an option part, it suits builders who want to refine a running car with a more rigid differential case instead of changing the full chassis configuration. Compatibility covers TB-05 PRO, TB-04, TB Evo.7 and TB Evo.6 chassis cars. In workshop use, the set fits naturally into a rebuild, maintenance interval or performance-focused differential refresh where stable oil behavior and precise shimming matter.
