XRAY RX8 Spring Steel Shock Shaft Upgrade - AM-RX8-308361 by Arrowmax  [AM-RX8-308361]

Durable TiN coated shafts for RX8 shocks

Arrowmax offers hardened shock shafts made for XRAY RX8 dampers, supplied as a matched four-piece set for wheel-to-wheel balance. These shafts use spring steel with a titanium nitride finish to lower friction and extend service life inside the piston assembly.

Built to replace stock RX8 shock shafts, the AM-RX8-308361 parts aim to stabilise damping consistency and reduce wear versus untreated steel. Lower friction at the shaft surface helps the shock oil and seals operate more consistently, making tuning results repeatable between runs.

Fitting follows standard shock service steps: remove the top cap and piston, swap in the new shaft while checking straightness and smooth travel, then rebuild and confirm travel and seal seating. Always double-check piston, bushing and overall shock length compatibility before final installation.

If you want lower internal friction and longer shaft life on RX8 shocks, these coated shafts are a direct swap that reduces maintenance and helps maintain consistent suspension performance.
