This is a complete set of assembled BRX80 Scale PHAT Axle Set. The BRX80 pin-to-pin axle width is 162mm or 6.378 inches, which is between the BRX70 and BRX90 axles.

The BRX80 axle is a performance-based, high mass heavy-duty axle set designed for 1:10 scale RC crawlers and trucks. It can be easily installed in any project build.

Similar to the BRX70 and BRX90 axles, this latest BRX80 axle is packed with many features; heavy weight for low CG, reversible axle bevel gear positions, optional leaf spring over and under the axle, optional CMS or axle-mounted servo setup, optional behind-the-axle steering, detachable aluminum CNC link mount and third member, adjustable caster angle and more. Comes with heavy-duty steel keyed AR44 axle gears for ultimate strength and durability, an input shaft, and AR44 compatible knuckles.

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.

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.

To setup this BRX80 front axle similar to the BRX01 stock axles, these two parts are:
  • Steel Leaf Spring Channel w/ Shock Mount for BRX70 / BRX90 Axle (2) BRLC7002/B
  • Aluminum Knuckle Arm (Low Profile) for BRX70 / BRX90 Knuckle (2) BRLC7010
