Sizing Links & Information

Looking for a HUGE improvement over the factory ride quality? We've got the cure! All Shock Therapy springs are manufactured here in the USA and custom tailored to your units specifics, we take into account; driver weight, vehicle accessories/gear, riding style, etc. All of this helps us to build the perfect kit for your application.

Some of the benefits of our Dual ate spring kit:

  • Increased ride height (average 1" to 2")
  • Greatly improved bottom out resistance
  • Much more smooth ride over chop/chatter
  • Greatly reduced rear end bucking

The Dual Rate Spring kit Includes:

  • 4 Upper Springs
  • 4 Lower Spring
  • 4 Patented Silent Cross Over Rings (2 Front, 2 Rear)

At STEP 2 of the check out process where it says "ORDER COMMENTS" you will need to list the following to make sure the kit is set up for your unit:


  • The accessories you have on the unit ( Bumpers, winches, tools w/ weight and location, Ice chest w/ weight and location, spare tire w/ location, etc)
  • The terrains you ride, list multiple if applicable (Dunes, desert, mountain trails, etc)
  • The Driver and passenger weight INDIVIDUALLY (If for a 4 seat only not 4 passengers if you are riding with them 80%-90% of the time)

*All of our proprietary springs are made in the USA from the highest quality CrSi materials. This means they are always the exact rate we want and don't fade or break. They cost more when made from this material but are absolutely worth it when it comes to function and longevity. They are also warrantied for life!*** ***POWDER COATING SPRINGS WILL VOID THE WARRANTY*****
