Preload Adjusters

A preload adjuster is a threaded collar that lets you dial in spring preload on coilover or height-adjustable suspension. By precisely compressing or relaxing the spring, you can fine-tune ride height, corner weight, and suspension response without changing spring rates. These components replace worn or missing factory collars and are essential for proper suspension setup on performance, track, and lowered vehicles.

Whether you are replacing a damaged adjuster or upgrading to a more precise piece, our collection covers common sizes and thread patterns. If you are unsure which preload adjuster fits your dampers, consult your coilover manufacturer’s specifications or reach out to our specialists.
