Why do stock UTV’s ride the way they do?

Have you ever wondered why UTV manufacturers don’t maximize the potential of the factory suspension? It is not because they don’t want to, that is for sure. One huge reason is they have to pass the Federal Motor Vehicle Safety Standard (FMVSS) ground safety testing which includes a 25mph roll over test on asphalt. Manufactures are often forced to stiffen up the suspension with heavier springs and sway bars and/or lower the vehicle's ride height to pass these tests. OEM shock companies have their hands tied with regard to suspension set up since their parameters are dictated by the manufacture who have to pass these tests. Another huge issue is the OEM has to create a set up that works for MOST customers in all terrain, forcing a one size fits all product.

This is where Shock Therapy comes in. We are able to unlock the hidden potential of the factory suspension that the OEM’s are forced to leave on the table. Furthermore, we can tailor the suspension specifically for your driving style, terrain and accessories where the OEM can’t possibly go. If you want the most plush ride quality possible while eliminating all bucking and bottoming out then you have one place to go, Shock Therapy.

Stage 1: The Dual Rate Spring Kit (DRS)

Shock Therapy’s dual rate spring kit, is the best starting point to upgrade your suspension set up. A Shock therapy dual rate spring kit is going to be custom tailored to your units specific. We will take into account, driver weight, accessories, terrain and driving style. Some of the benefits of the Shock Therapy dual rate spring are: 

• Increase ride height
• Increased bottom out resistance
• Reduced bucking
• Smoother ride quality over chop and chatter
• No Sagging
• Life time warrantied springs
• Springs manufactured in the USA

Stage 2: Shock Therapy (RIS) Internal Work

Shock Therapy’s internal valving is custom tailored to the driving style of the unit and the different terrains you ride. Shock Therapy makes major modifications to the internals of the shock, as they call it, the heart of the shock. The modifications performed inside the shock help promote plushness through small chop and chatter, increased bottom out resistance at full compression, and removes stiff ride quality at moderate to low speeds. Shock Therapy internal valving is not only for racing applications, but is for recreational riders looking to get the most out of there suspension.

• Piston
