I have the Fox QS3 and just changed out my tires and would like to add a couple inches of preload. What tools are you all using to accomplish this? Any links or specific wrench sizes are appreciated!
It depends on the diameter of the shock, I used this on my 2-1/2" Talon shocks. I just Googled 2-1/2" Fox spanner and it popped up. Whatever you use, jack the buggy up as high as possible to unload the springs, it'll make it MUCH easier.
I use a pair of knit gloves with rubber coated palm. Jack it up, loosen the lock ring and turn them down by hand. Hella faster and less bloody knuckles.
