Boom Racing brings you a new and exciting product - Complete Assembled BRX70 Scale PHAT Axle Set.
The BRX70 axle is Boom Racing's new narrow axle. Packed with many desirable solid axle features; heavy weight for low CG, reversible axle bevel gear positions, leaf spring over and under axle (optional), chassis mounted or axle mounted servo (optional), behind-the-axle steering (optional), detachable aluminum CNC truss, adjustable caster angle. It uses the widely available AR44 axle gear, input shaft and AR44 knuckles.
This is a performance based, heavy and narrow axle set designed for performance based scale RC builds. Use this axle as a base for any custom builds.
Includes red color Diff Cover; optional Black color Diff Cover is available here.
Includes black color Third Member (fits Reverse AR44 Helical Cut Bevel Gear for running Counter Rotating Center Drive Shafts usually used in the rear axle). Note red color Third Member will not fit Reverse AR44 gear.
BRX70 front axle is slightly wider than the BRX70 rear axle. This provides better steering performance and stability for the chassis.

Hardware
You will need:
For Axle Mounted Servo setup, the optional BRX70 aluminum servo mount is needed.
For 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, additional optional parts may/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.
