May not be the best answer - but the 04 Mule 600 4x4 the rear shock was adjustable but not the front. I'm pretty sure - but cannot guarantee that the 2008 3010 wasn't adjustable. I could be mistaken. Even though your oem struts/shocks may not be - here's something you might be interested in - aftermarket kits to make the preload adjustable on different setups. This particular one was for the mules up to 07 - There should definitely be something for the 08s as well. All The Best, Justin Lee, 17 South Industries, LLC
