This shock spring set is produced for Works'91 TeamSpec applications and is supplied as a matched front and rear set with two springs per end. The items are intended solely as RC suspension parts compatible with Yokomo YZ-W91TS and YZ-W91 chassis.
Use the springs as replacements or as a basic tuning measure to adjust spring preload and ride height. When fitting new springs, make sure they are installed in matching pairs and that free length and seating on the shock shaft are checked prior to final assembly to preserve balanced suspension behavior.
For users running Works'91 TeamSpec chassis who need direct-fit replacement springs or a straightforward front/rear swap to change handling balance, this kit is listed for YZ-W91TS and YZ-W91.
