Yamaha YZ 250 F Shock Pre-Load Adjuster - XTrig - `14-`18 is a precision mechanical replacement for the standard preload rings on your shock. It allows quicker, repeatable preload changes so you can dial sag faster between runs.

This XTrig pre-load adjuster is engineered for off-road and motocross use, giving riders a larger usable adjustment range through full thread utilization. The design reduces dirt buildup around the adjustment surface, helping maintain smooth operation in muddy or dusty conditions. Constructed from durable materials, it’s intended to withstand regular trail and track use. Installation is straightforward in most cases, though some shocks may require partial disassembly for fitment. Compatible with Yamaha YZ250F models 2014–2018 (and fits select YZ450F 2014–2017 models).
