Stiffen the Rear End with XRAY 353116 XB9 Hard Composite Arm

Built for racers who run hot tracks, the XRAY 353116 XB9 Hard Composite Rear Suspension Arm uses a specially formulated composite to cut flex when temperatures rise. The result is a more stable rear end and dependable handling under sustained heat.

Formulated for High-Temperature Performance

XRAY developed this hard-arm compound to resist deformation in warm conditions, delivering consistent geometry and predictable response lap after lap. Its increased rigidity improves stability but can feel less forgiving on heavy impacts.

Longer Geometry for Improved Tracking

The extended length of the arm helps straighten the handling balance, offering smoother transitions and better rear traction for drivers focusing on precision and corner speed.

How does the hard composite perform on asphalt compared to off-road clay?

The compound in the XRAY 353116 XB9 arm is aimed at high temperature scenarios common on asphalt and abrasive tracks. It reduces flex and holds suspension geometry better under heat. On loose clay the extra stiffness can change feedback, so suspension tuning may be needed.

Will I need to adjust shock settings when fitting this arm?

Yes. Because the arm is stiffer, you may want to soften shock damping or adjust spring rates to retain mechanical grip. Start with small changes and test for reduced oversteer or a harsher feel on bumps.

Is this part a direct swap for the XB9 stock rear arm?

This suspension arm is designed specifically for the XRAY XB9 platform. It should bolt in as a direct replacement for XB9 rear arms, but verify fit and alignment during installation and check for any clearance issues with bespoke setups.
