Leaf Springs - How do you know what to believe when every source lays claim to having the most durable and best riding leaf springs? Some suppliers suggest that they have reinvented the wheel. Actually, there have been no light truck spring design breakthroughs in quite some time. Comprehending how spring characteristics differ requires an understanding of spring rate and rate curve. Rate is a measurement of the load required to compress the spring a given distance. In other words, it is a gauge of spring strength and flexibility. "X" amount of rate is required to support "X" amount of weight. Rate curve is a measurement of load variations as the spring is compressed; a smooth, linear rate curve is desired. Rate and rate curve are determined by several factors including: number of leafs, material grade and thickness, leaf length, leaf end configuration and interleaf friction. 
Leaf springs sold individually. Bushing sets include bushings for pair of leaf springs.

Developing a good functional design involves closely evaluating the vehicle’s spring rate data, plus its overall drivability then using this information to design a product matched to the vehicle. All Superlift springs are made with Spec. 5160 spring steel. Our various design elements include, depending on application: tapered leafs, shot-peening, different clip styles, spring inserts, eye-bushing style, military-wrap eyes and functional compression travel control.

Coil Springs - Like our leaf springs, Superlift coils are manufactured from Spec. 5160 spring steel. Our designs give you the desired ride height increase, with minimal (if any) effect on ride quality. All coils are preset solid (fully compressed and stressed in the manufacturing process) to minimize settling. Coils are either powder coated or vinyl coated in black, depending on application. Sold in Pairs.

U-bolt sets include 4 u-bolts with nuts & washers.
