Slash 4x4 Rear Arm Brace for TRAXXAS - Reinforced Support SLA009N by GPM  [SLA009N]

Rear lower arm reinforcement for Slash 4x4

This reinforced rear arm brace is an aftermarket upgrade for the TRAXXAS Slash 4x4 chassis designed to stiffen the rear lower arm area and cut unwanted flex under load. The brace helps deliver a more consistent rear-end feel for drivers who push hard off-road or over jumps.

Fitment is based on the Slash 4x4 stock mounting points; fitters should check alignment with the rear suspension mounts and use the original screw locations. Minor trimming of adjacent plastic panels may be needed on some chassis preparations. The part adds stiffness without changing the basic suspension geometry, so you may still want to revisit shock tune or ride height after installation.

From a setup perspective, adding a rear arm brace tends to stabilise arm movement and make rear traction steadier, helping you balance front and rear grip when adjusting damping or spring rates.
