Universal ShockWave 7000 Series-Pair

The 7000 and 8000 series ShockWave, with a smaller diameter and longer stroke, will have a less load capacity and a softer spring rate that is appropriate for the rear of most vehicles with a solid rear axle. The spring rate and load capacity is influenced by the profile of the lower piston. A straight piston will offer a very linear, or constant spring rate, throughout its travel. A tapered lower piston will result in a more progressive spring rate, much like the double convoluted airspring.
