OEM springs tend to fatigue rapidly even with low mileage. The High Lifter Lift Springs were engineered to provide about 100 additional pounds of capacity (per 4 set) over the new stock springs. They were also designed to make a significant difference in the performance of your ATV with as little affect as possible on the ride and handling of the machine. And here's a big bonus, a complete set of the Lift Springs may be installed for substantially less than the cost of one replacement OEM shock.
