Yamaha YZ 450 F Shock Pre-Load Adjuster - XTrig - `14-`17 is a precision-engineered replacement for the stock preload rings on your YZ450F. It provides quicker, more repeatable preload changes so riders can fine-tune sag and suspension setup between practice, qualifying and race runs.

The XTrig unit uses full thread utilization to engage the entire length of the shock body threads, giving a broader range of adjustment than standard rings. Its design reduces dirt accumulation around the adjuster, helping maintain smooth operation in off-road and motocross environments. Constructed from durable materials intended for hard use, the adjuster is straightforward to install on most shocks, though some models may require partial shock disassembly for proper fitment. This part is aimed at riders who make frequent suspension tweaks to match changing track conditions.
