Just installed my level 4 dual rate… Just installed my level 4 dual rate springs last night on my 2017 Polaris RZR XP 1000. Will try them out on trails this weekend. Online order experience was good, with prompt shipment. Quality looks good, everything fit correctly and online instructions made install easy.

Tender springs The tender springs were easy to install, work great, only complaint is that they are noisy when the crossiver ring rubs the tender spring and the spring divider rubs the shock body causing wear on the shock body, I have tried repositioning and indexing the springs to no avail. I emailed Shock Therapy about this but got no reply.

They have very excellent quality… They have very excellent quality products, some of the best. I didn't rate 5 stars because I believe that got too big too quick. I have had mixed results with customer sales reps, and sent non-fitting items that were rushed out before a diligent R&D was performed. However, the customer service dude then went above and beyond to rectify the situation. But for my level 3 spring kit, I got a one size fits all treatment and felt a bit dumbed down by the rep even though I know my way around a shim stack. ( and the primary rears are the wrong rate for my application). I don't think a set of Walkers rebuilt and sprung by them couldn't last more than 4000 miles until they disintegrate into High Desert yard art. I would buy there stuff again though, and again. Top notch machining, killer tolerances, and USA made. Their Tech guys/gals know their stuff. I see why so many companies imitate ST products.

Over priced Over priced. Picture does represent the quantity your paying for. Needs to better explain their options and what you'll need for full install.

The limit straps are a big plus The limit straps are a big plus. Will engineered. Nose is gone. The only reason for only 4 stars is the price. I have 2 cars His and Hers. Both with ST suspension front and back. And now both with limit straps. I think every one knows where I am going with this. Thanks ST for another outstanding product.
