Rear shock

Hi all,

    Hope everyone has had a great summer. I want to adj my rear shocks preload and damper. Which way do I turn them to stop it from bottoming out with 2 up? What is setting 1 so I have starting point? Do you want more or less preload and damping with 2 up? Sorry if these questions sound obvious.

    Also it says on damping there should be 12 turns. Mine turns more than 12. Is this bad?

Thanks,

Scott

If you want to try to prevent the shock from bottoming, you need to add preload to the spring (which means you need to move the adjuster so it compresses the spring more).

"Typically" whenever you add more preload, you also need to add more damping.  Usually the damping is increased when the damping adjuster is turned "in" (clockwise) which should restrict oil flow more.

   I doubt that you will be able to stop it bottoming by adjusting the preload. It may prevent it occasionally but the typical 20 something plus year old spring is way too soft to prevent it. Even when new, they were on the soft side. A new heavier weight spring may be the cheapest way to go but in my opinion save your dollars for the RPM shock. From all the positive feedback, it's well worth the money.   Pete.
