If you’re tired of replacing cracked OEM gearbox housings, this is the fix.
Our H&S Reinforced Planetary Gearbox Housing is designed as a stronger alternative to the full OEM gearbox. Instead of buying the same housing again, reuse your gears (or pair this with an OEM rebuild kit) and build a more durable gearbox.
We’ve seen too many OEM planetary gearboxes fail at the mounting ears. This housing has been redesigned and reinforced in the exact areas that commonly crack — thicker base, added material, and gussets where the load lives. Same gears. Same fit. Stronger foundation.
This housing is designed to be used instead of buying a complete OEM gearbox.
To build a complete assembly, you’ll do one of the following:
Transfer your existing planetary gears into this housing
OR pair this housing with an OEM planetary rebuild kit
Either way, you end up with a complete gearbox built around a reinforced case — without re-buying the same weak housing again.
