TRAXXAS Slash 4x4 Rear Arm Brace by GPM SLA009N  [SLA009N]

Rear arm brace for Slash 4x4

This rear arm brace is an RC-scale accessory produced for the TRAXXAS Slash 4x4 platform, intended to reinforce the rear lower arm area and reduce flex under load. It serves as a focused upgrade for hobbyists who want a more predictable rear end during aggressive off-road use.

Installers should verify alignment with the Slash 4x4 rear suspension mounts and use the stock mounting points; minimal trimming of surrounding plastic is occasionally required depending on chassis prep. The part functions as a stiffening element rather than altering suspension geometry, so changes to ride height or shock settings may still be needed to fine-tune handling.

In tuning terms, adding a rear arm brace can reduce unwanted arm movement and make rear traction more consistent, which helps drivers dial in balance between front and rear grip when adjusting shock damping or spring rates.
