J-TECH spring adaptors reduce the inner diameter of a coil spring to fit narrower shock bodies.

2 required per spring, pair shown for display purposes only.

Available to fit all shocks with spring inside diameters (ID) of 35mm (Fox), 36mm (CCDB, Bos, Ohlins, etc) and 38mm (RS Vivid). 

Also available to fit a 38mm or 1/2" ID spring (like MRP or Rockshox) to 35mm (Fox) and 36mm (CCDB, Bos, etc) shocks. These are listed as 35/38mm and 36/38mm respectively.
