Slash 4x4 Rear Lower Arm Brace - Chassis Reinforcement SLA009N by GPM  [SLA009N]

Rear arm reinforcement for improved stability

This aftermarket rear arm brace is designed for the TRAXXAS Slash 4x4 platform to strengthen the rear lower arm area and reduce flex during hard off-road use. It is aimed at drivers who want a more controlled rear end when tackling rough tracks and jumps.

Fit the brace to the Slash 4x4 stock mounting points and check alignment with the rear suspension mounts before tightening. Some chassis may need light trimming of surrounding plastic for a flush fit. The component is a stiffening mod and does not deliberately change suspension geometry, though you might revisit shock damping and ride height to fine-tune handling after installation.

Adding this brace typically lowers unwanted arm movement and produces steadier rear traction, which can simplify balancing grip between the front and rear when tuning springs or dampers.
