This is a complete front assembled BRX90 portal PHAT™ axle set.
This is a high-performance, heavy-duty axle designed for scale truck project builds. The modular design makes it suitable for different project builds, and the width of the BRX90 axle makes it perfect for any standard 1/10 project rigs.
Packed with many desirable features; a heavy-weighted cast alloy axle housing for low CG, link setup or leaf spring over and under axle setup, chassis-mounted or servo-on-axle setup, front tie-rod or behind-the-axle steering setup, 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 heavy-duty steel triangular keyed AR44 axle gears (30/8T) and a pair of BADASS™ steel universal drive shafts for ultimate strength, performance, and durability.
The portal gearbox is designed with four heavy-duty steel gears each for strength and durability. The portal spindle rotates in the same direction as the driveshafts; the axle can fit directly into many standard drivetrain setups without changing the rotational direction of the drivelines.
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).

You will need:
For Axle Mounted Servo setup, the optional aluminum servo mount is needed.
For the Chassis Mounted Servo setup, a panhard link is needed (as almost every car has a different setup, we leave this part up to you).
For Leaf Spring setup, leaf spring channel may or may not be needed depending on your setup. Leafs can be mounted directly on top and under the 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.
