This is a complete set of rear assembled BRX70 portal PHAT™ axle set.

The BRX70 axle is Boom Racing's narrow axle. This is a heavy-duty and narrow 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).

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.
