Stiffen the Rear of Your RX8 with XRAY 343133-H

The XRAY 343133-H Rear Upper Suspension Arm is manufactured from a hard composite that delivers greater strength and longer service life for RX8 series cars. This harder variant gives a firmer rear end, helping drivers maintain consistent lines and reduced flex during aggressive lap work.

Track-Focused Geometry

The extended arm profile spreads loads more evenly across the suspension, lowering the chance of flutter and helping preserve wheel alignment. Expect crisper rear response and reduced component wear when you move to this hard arm from a softer option.

Fitment and Quick Swap

Made to fit RX8 2025 models, this arm installs into the factory mounting points without modification. Its precise fit and rugged construction make it a practical upgrade or replacement for racers who log regular track time.
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.

Will the XRAY 343133-H fit older RX8 variants?

The arm is designed for the RX8 series with an emphasis on the 2025 platform; check your chassis mounting layout to confirm compatibility with earlier revisions.

Do I need different shock settings after fitting the hard arm?

You may need to retune rear shock compression or spring rate slightly to balance the stiffer rear response, but standard shocks and mounts usually remain compatible.

What routine checks keep the arm performing well?

Inspect for cracks or stress marks after heavy use, keep hinge pins and bushings clean, and torque mounting hardware to spec to avoid unwanted movement.
