Fine Tune Rear Grip with the XRAY 303173-H Long Arm

The XRAY 303173-H Rear Suspension Arm is crafted for drivers who want a more planted rear end in mixed conditions. This long right arm uses a hard composite to improve rear stability and make handling more consistent when traction is limited.

7mm Extra Length for Tough Surfaces

This arm extends 7mm beyond the standard length to help create additional rear traction on low grip tracks. The longer geometry promotes better tyre contact during cornering and exit phases.

Alternative Shock Mount for Lowered Balance

Alongside the stock shock position, a 4mm lower mounting option is provided; installation requires the optional lower ULP shock tower. Choosing the lower mount reduces roll and helps the car hold line through technical sequences.

Strong Hard Composite with Anti-Roll Bar Capability

Made from a purpose-designed hard composite, the arm is light yet robust enough for regular competition. The built-in anti-roll bar mount gives quick setup options for drivers wanting to tune rear roll stiffness.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I use this arm on carpet tracks?

Yes, the extra length can help carpet setups that lack rear bite, but you may need to soften rear springs or adjust toe to avoid understeer.

Is installation difficult for a club builder?

Installation follows standard arm replacement steps and is straightforward for anyone familiar with rear hub removal. Ensure you transfer bearings and check roll centre alignment after fitting.

Will the arm change rear camber gain?

The longer arm alters rear geometry slightly, affecting camber gain characteristics. Expect subtle differences; recheck suspension angles and adjust toe and camber to suit your driving style.

Does the XRAY 303173-H require special mounting hardware?

It uses the standard mount pattern but the 4mm lower position needs the optional lower ULP shock tower. Use original hardware where possible and replace worn pins or bearings during fitment.
