This is a complete set of rear assembled BRX90 portal PHAT™ axle set.

This is a heavy-duty axle set designed for performance-based scale RC builds. Designed for both linked and leaf spring setups. Use this axle as a base for any custom builds.

Packed with many desirable features; a heavy-weighted cast alloy axle housing for low CG, reversible axle bevel gear positions, leaf spring over and under axle (optional), detachable aluminum CNC truss, adjustable caster angle, and more.

It uses top-quality drivetrain components that are heavy-duty and efficient, including a set of hardened steel triangular keyed AR44 axle gears (30/8T) and a pair of BADASS™ steel rear drive shafts for ultimate strength and durability.

The portal gearbox is designed with four heavy-duty hardened steel gears each for strength and durability.

Includes black color XT diff cover and black color third member unit (fits Reverse AR44 Helical Cut Bevel Gear for running Counter Rotating Center Drive Shafts usually used in the rear axle).

Specification:

  • Width: 188.3mm / 7.41" pin-to-pin (BRX90 portal axle front and rear axles are the same width)
  • Requires 44mm / 1.73" wheel barrel clearance (to clear the entire portal gearbox)
  • Portal gearbox ratio: 1:1
  • Weight: 261.5g
  • Portal Gearbox Size:
    • Width: 23.5mm

  • CNC aluminum portal lockout and cover
  • BADASS™ heavy-duty steel rear driveshafts and portal driveshafts for ultimate durability and strength for the axle drivetrain
  • Four heavy-duty hardened steel metal gears in each portal gearbox

  • Cast PHAT™ axle housing - strong, durable, and heavy which keeps the CG low
  • Anti-twist steel brackets to prevent axle twist
  • Reversible axle gear in the housing (swap gear to the opposite side for counter rotation center drivetrain setup)
  • Standard AR44 high pinion gear & input shaft for better clearance
  • Leaf spring over and under the axle housing option
  • CNC aluminum truss included for linked setup (remove truss for leaf spring option for ultimate scale look)

When you receive the axle:

Make sure to grease up the axle set. You can fill up the empty space with diff grease surrounding the bevel gear and input shaft.

The gear positions are factory setup and should be ready to go. Rotate the drivetrain by hand for physical inspection.

Install spacers accordingly between the center driveshaft and the input shaft to prevent input shaft from unnecessary slop.
