Contact our sales team for orders or questions:


Designed for off-road and motorsports applications that require high ground clearance, Crawl King portals offer an additional 4.9″ lift from the bottom of the diff. The 1.5:1 reduction in the gearboxes transfers torque while keeping stress on the axle relatively low while the extra mass close to the ground level acts as a countermeasure to the lift. Combining AxleTech US Gear portal boxes with genuine Dana Spicer housings and gearing, this set of axles will be custom built and shipped to each customer’s specifications.

  • AxleTech US Gear Portal Wheel Ends
  • Spicer High Clearance High Pinion Ultimate 60 Front Housing
