Boom Racing Complete Assembled BRX90 Portal PHAT Axles

The BRX90 fits most standard-sized 1/10 vehicles, perfect for your custom builds.

Packed with many desirable features; a heavy-weighted cast alloy axle housing for low CG, setup of your chassis using links or leaf spring over and under the axle, chassis-mounted or axle-mounted servo, behind-the-axle steering or front tie rod, detachable aluminum CNC truss, adjustable caster angle and more.

Our four-gear portal gearbox also means you can use them to fit directly onto most drivetrains without needing to change the rotation direction.
