For those who ride at slower speeds, with big tires and heavier loads, the Lift Springs will be a welcome and economical upgrade. Depending on the make, model, and current modifications to the unit, the High Lifter Lift Springs have been known to add on full inch of suspension lift, however, it’s not guaranteed. The Lift Springs add some stiffness to the ride and decrease roll, but have not been found harsh or uncomfortable by anyone who has ridden them. One thing is for sure. If you are a hardcore mud rider or you carry a load, your ATV could stand a heavier load capacity. The High Lifter Lift Springs are just what the doctor ordered!
