Trailer Gearbox Rebuild Kit


8 in stock (can be backordered)



Did you inadvertently use an impact or hammer drill instead of a regular drill? Don’t worry, we have now made it super easy for you to get your replacement gears. Here are all the parts needed to rebuild your Trailer Gearbox if damaged. Both small gears should always be replaced as a set. If you break one, the other will be damaged from the same force that broke the other. Replacing the keys or spacer is not required but they are included in case you lose one.

If you don’t feel comfortable taking it apart and putting it back together, you can always mail the gearbox back to us and we will install the parts for you at no extra charge.

What’s included:

2- Small Gears

2-Gear Keys




An Installation video will be added here and to our Facebook page in the coming days. Thank you for your patience.
