The ICON multi-rate leaf spring is a modular user-adjustable product that offers a major performance gain for almost every accessory & gear setup imaginable. To improve the front-to-rear balance and increase the compliance of the truck the spring rate has been lowered significantly compared to the OE spring. While many Ranger owners will embrace this there are those who have outfitted their trucks with a significant amount of weight in the form of a bed rack roof top tent spare tires parts or other additions. Taking this into consideration the leaf pack was designed with an additional leaf (included with kit) that can be exchanged or added to the pack yielding additional spring rate that will handle more "outfitted" vehicles. Aditionally features like greaseable tip inserts and leaf separators reduce friction and increase ride comfort while heavy duty eyelet bushings provide excellent durability and noise free operation.
