Drenth Motorsport Gearbox Rebuild Service

Drenth Motorsport H-Pattern & Sequential Gearbox Rebuild Service

Keep your Drenth Motorsport H-Pattern or Sequential gearbox performing at its best with our professional rebuild service in the United States—no need to ship your gearbox overseas.

The process is simple:

1. Secure your gearbox on a small pallet.
2. We provide the necessary shipping paperwork and schedule the shipment.
3. Your gearbox arrives at our facility, where we complete a full teardown, cleaning, and detailed inspection of all internal components.
4. After inspection, we provide a condition report and recommend any necessary repairs or replacement parts.
5. Once approved, we complete the rebuild process and ship your gearbox back to you, ready for competition.

Every gearbox experiences different levels of wear depending on usage, power level, and application. Some units may only require routine service with bearings and seals, while others may require additional internal components such as gears, dog rings, shafts, selectors, or other wear items.

Parts are billed separately and only with customer approval.

From inspection to rebuild, 5150 AutoSport handles the entire process to help get your Drenth Motorsport gearbox back to race-ready performance.
