Our springs have an inner diameter of 36.3mm. Please consult your shock's manufacturer for their official clearance.  We do not fit any Rock Shox dampers.

However, outside of Rock Shox, we do fit many current dampers. If you have a FOX DHX or earlier shock, you will need to use our Spring Converter (.DB11253H). Current FOX products do not require this converter. Again, please consult your shock's manufacturer for their recommendations.
