NT1 Rear Swing Shaft XN1-14 by 3Racing  [XN1-14]

Technical overview

The XN1-14 rear swing shaft is a direct-fit replacement for the XRAY NT1 rear swing arm pivot. It is intended to re-establish correct pivot alignment and reduce lateral play that degrades handling precision after impact or wear.

Compatibility and fit: designed to match NT1 rear suspension bores and link interfaces, the shaft reinstates the designed pivot axis without altering factory geometry. Inspect swing arm bore tolerances and retention method to ensure the correct installation and repeatable fitment.

Service notes: during replacement remove the rear bulkhead and swing arm assembly, extract the worn or bent shaft, and fit the XN1-14 ensuring positive seating and secure retention. Verify free rotation through full travel and confirm no lateral wobble remains before track use.
