This kit gives a substantial improvement in ride quality while improving handling as well at G-out resistance. We have found the perfect combination of spring length to rate ratio and are very happy with our results. This kit is for all four corners of the machine. It provides a short spring, a long spring and a delrin spacer for each shock. The secret is in our short springs. We have found a perfect rate which allows us to custom tailor our long springs, (which determines the final rate of the suspension) to each individuals needs.
Rates - The Standard rate kit works great for 2-4 people without a ton of extra gear loaded beyond what the average owner takes with them for a day on the trail or dunes. The Heavy Duty kit is recommended when carrying 4 people and a lot of gear most often
