XRAY RX8 Hardened Shock Shaft (spring steel) by Arrowmax AM-RX8-308361  [AM-RX8-308361]

Hardened shock shafts for RX8

Arrowmax has released a set of hardened shock shafts intended for XRAY RX8 shock absorbers, supplied as a matched set for wheel-to-wheel RC use. The shafts are manufactured from spring steel and receive a titanium nitride surface treatment to reduce friction and slow wear in the shock piston assembly.

Designed as a direct replacement for compatible RX8 shock kits, these shafts focus on delivering more consistent damping action and longer service life compared with untreated steel shafts. The reduced surface friction helps the shock oil and seals perform more uniformly, supporting repeatable tuning results across runs.

Installation is the same basic procedure as replacing any shock shaft: remove the shock cap and piston assembly, swap the shaft while checking for straightness and smooth travel, then reassemble and verify travel and seal seating. As with all hop‑ups, confirm fit with your existing pistons, bushings and shock length before final assembly.

For RX8 owners seeking lower internal friction and improved shaft longevity, these hardened, coated shafts provide a straightforward parts swap that supports more consistent suspension behavior and reduced upkeep.
