What is a Portal Axle?

It’s a gearbox

that replaces your wheel hub

with an offset output

Performance Specs

  • Lifts your axles, not just the chassis. Run 35s with the clearance of 43s.

  • Multiplies your axle ratio by 1.25, reducing stress on your axle shafts and differential.

    3.73 * 1.25 = 4.66

    4.10 * 1.25 = 5.13

  • 40 Spline Output, 1 Ton Bearings.

  • +4in per side.

Modular Design

Only four vehicle specific components:

  • Mount Plate

  • Input Gear

  • Brake Caliper Mount

  • Drive Flange

  • The core components remain the same on any application.

  • Standardizing more parts reduces costs by increasing manufacturing volume.

  • Upgrading to a new vehicle and want to keep your portals? No problem, we can provide new, vehicle specific parts for your new build.

  • New vehicle applications can easily be added, enabling customizations like different bolt patterns and offsets.

Components

  • Straight tooth spur gears for maximum strength and reliability. Teeth are ground after heat treating to reduce noise.

  • Billet machined from 6000 series aluminum for increased strength and precision.

    • Mount plate attaches to factory hub location.

    • Cases attach to the mount plate with 6 bolts for increased stiffness, which reduces the risk of premature gear failure.

  • SKF bearings are used throughout due to their renowned reliability. One ton output bearings ensure worry free wheeling even on the biggest obstacles.

    • 40 spline output shaft is designed to take big hits and increase your smiles per gallon.

    • Drive flanges enable flexible bolt patterns and easy serviceability of output bearings.
