TRAXXAS XRT 8S 7.0mm Shock Shaft Replacement 4140/7075 XRTDP by GPM  [XRTDP]

XRT 8S shock shaft core replacement

This kit provides replacement shaft cores for the TRAXXAS XRT 8S platform and fits GPM shock units. Shafts are manufactured from 4140 medium carbon steel with key components in 7075 aluminium, and the diameter is increased from 5.0mm to 7.0mm to reduce deflection while remaining compatible with original shock bodies.

The components suit front or rear damper positions and are compatible with both GPM and factory shock absorbers listed for this model. An oil seal replaces the classic O-ring arrangement to deliver smoother piston action and better oil containment under movement.

When installing, confirm piston and seal dimensions, test for smooth sliding inside the shock body before tightening, and keep shock oil and valving matched to your handling goals. The change focuses on improving shaft straightness and longevity rather than altering damping behaviour.

Choose these shafts for tougher, straighter shock rods and more dependable sealing; always verify fitment in your specific shock bodies prior to final assembly.
