💡 How do you stop a reverse gearbox from stripping gears under heavy load?

You need sealed bearings and hardened teeth that lock tight so power hits the ground instantly.

- Hardened alloy splines grip the converter shaft dead solid even on bumpy dirt tracks.

- Slick internal routing keeps oil cool so you get handy throttle response when pushing limits.

- Pre tuned clearance gaps prevent metal chatter during fast downhill sprints and sharp turns.

- Drop in design saves sweat compared to messy custom weld setups at the machine shop.
