XRAY 303173-H Rear Long Right Suspension Arm - Precision Balance  [XR-303173-H]

Refine Chassis Balance Using the XRAY 303173-H Long Rear Arm

The XRAY 303173-H Rear Suspension Arm is aimed at drivers seeking improved rear-end predictability on technical layouts. This long right arm is produced in a hard composite to sharpen grip and stabilise handling where grip is limited.

Extended Length Designed for Low Grip

The arm is 7mm longer than standard items, a change that helps generate extra rear traction in low grip situations. The geometry shift improves tyre contact through corner apex and exit phases.

Adjustable Shock Mounting for Lowered Roll Centre

It retains a standard shock mounting and introduces a 4mm lower option that requires the optional lower ULP shock tower. Selecting the lower mount lowers the centre of gravity and improves steering response through slow technical corners.

Engineered Hard Composite with Anti-Roll Bar Feature

Built from a specialist hard composite, the arm aims to combine stiffness and resilience for competitive use. The integrated anti-roll bar mounting point allows straightforward tuning of rear roll stiffness.
