If you’re looking to give your ride a serious upgrade, the Zumbrota Drivetrain Axle Assembly is where it’s at. These axles aren’t just slapped together; they’re rebuilt with a level of precision that you can really feel on the road or the trail. Each assembly goes through a rigorous inspection process—think straightness checks, crack assessments, and surface wear evaluations. You won’t find any shortcuts here.

What really sets these axles apart is the thorough inspection of all internal components. We're talking about the ring and pinions, internal gears, clutches, and carriers—all of it gets a full once-over. And don’t worry about old bearings and seals; everything gets replaced. This attention to detail means you can hit the road with confidence, knowing that your axle is ready for whatever you throw at it.

One of the coolest features is how they set the gear backlash. This isn’t just about making things fit; it ensures proper lubrication and keeps things running smoothly and quietly. Plus, the axle tubes are inspected to meet OEM straightness standards, so you know they’re built to last.

Cleaning is another area where Zumbrota shines. They use a unique hydro-blast rinse and sandblasting technique that really brings the parts back to life. It’s not just about looks; it’s about performance. The proprietary deep cleaning process ensures that every nook and cranny is spotless, setting a high bar for remanufactured axle assemblies.

Features:
  • All tubes are inspected to ensure they’re straightened to OEM specifications.
  • Housings are rigorously tested for any surface wear or cracks.
  • Every internal part gets a 100% inspection—ring and pinions, internal gears, clutches, and carriers.
