Motorcycle Shock Spring Preload Adjuster Top

If you have pre-loaded the spring as much as you can, and you still have too much rider sag, it's time to get a stiffer spring rate. If you've removed all pre-load off the spring, and you don't have enough rider sag, it's time to get a softer spring rate. Read more about suspension spring choice for finer details and expert tips - then see our Shock Springs & Hardware Category to find your new rate and the collars that sit against the preload nut.

These are the upper rings - they lock the lower ring in place so it can't shake loose. If you rarely need to change your preload adjustment standard sets are great, but if you find you can't swing a preload spanner inside that tight trellis frame consider a mechanical preload adjuster - they fit to shock bodies like a regular preload nut but change thickness using a regular socket (on an extension if you want - for hard to reach places). If you're riding with a pillion passenger, multiple terrains or big changes in luggage, you should think about a hydraulic preload adjuster instead - it does the same thing as a mechanical one, but with a simple to use knob and no tools by the side of the road.
