Shock Therapy springs... Not happy, what gives?

Ok who has installed the shock therapy springs? I recently installed them and my front ones suck. They make a loud noise and I can feel the clunk when they extend when going over a log or going down into a hole on the trails. High speed they handle great, no noise when hitting some dips. I'm being told by ST that that's what they refer to as extension clunk and all rzr do it. Well on 3rd rzr here, never had this issue, nor did it do it prior to changing from Racer Tech to the ST springs.

My springs do the same just installed straps to stop this, also replaced the springs in front with their fix, not been on trails yet but riding around home it seems to be alot better ride now.

PRP makes an affordable set of limit straps.

Reading many forums, alot of RZR's have the clunk from full extension, mine does it and it is fixed with limit straps, just have not done mine yet. Not sure why yours didn't do it before.

Re: Shock Therapy springs... Not happy, what gives?

Mine has never made a clunking sound with stock springs or the racer tech springs that I currently run, and I do like to catch some air. That clunking sound would annoy the hell out of me, as well as having to install limiting straps to remedy it

I have Shock Therapy limit straps. They are adjustable in length. I adjusted them so that they engage 1/2" before the shock reaches full extension. No more clunk even when I go airborne.

Not the springs. Shock Slap is what it is often called, and it won't hurt anything. Newer machines with the WE won't have it, as WE has added an internal "cushion" to help eliminate the sound

Well this all sucks as far as I'm concerned. Buy springs to improve the ride and Shock therapy are not doing that as they now induce this extension clunk and on top of that they don't even sell straps for machines they sell springs for.

2 thumbs Down is my rating, save your money.

The clunk is the shock topping out. I recently bought the spring kit for my 19 xp41000. I dont have the issue but understand your frustration. I dont believe the limit straps are the answer , I think shock therapy has your particular rzr over sprung. Have you played with your ride height? Try moving the crossover up or even taking it out. To have to buy the limit straps is a joke and if that's their answer ask for a return on your springs.

Incorrect -the clunk comes from the piston slapping the bottom of the shock upon extension. Remove he crossover? That defeats the entire purpose of dual rate setup. Limit straps will 100% cure this issue. This problem occurs with a lot of stock machines when preload is added as well as machines where the springs have been changes. It does not hurt anything but it's annoying.

S.T. should tell you first that with their spring set up you will need limit straps. The clunk happens because the shock is rebounding to fast and "topping out" . Their not the right springs for his machine.

He doesn't "need" limit straps because it's not a "problem". This is a common thing and not just with ST.

With regards to not needing them, I sure as hell do not want to ride listening and feeling them the way they are now.
