4-Link Rear Suspensions Designed to Offer More Versatility
The 4Link is RideTech's universal 4-link for custom applications, it's responsible for holding the rear axle of a vehicle and is used to replace old leaf spring suspensions. It requires some welding, but it is a simple and very effective way to upgrade your vintage suspension. The 4-Link can be equipped with a RideTech air suspension system or coil-over by using their cross member kit. The 4-Link comes in two designs, triangulated and parallel, each with their own advantages.

Triangulated 4-Link System
The triangulated 4-Link is designed for the professional builder who wants a straightforward, no-compromise rear air ride suspension. The triangulated version Air4Link is a tubular version of the tried and true rear suspension that GM has used since 1964. Welding and basic fabrication skills are needed. As a result, the triangulated Air4Link is highly adaptable to a variety of custom installations. The triangulated 4-link can use a CoolRide style air spring/bracket/shock arrangement or a rear ShockWave as an upgrade option or can be used with the simple coil-over shock set-up. For the professional shop or advanced installer, the triangulated Air4Link is the top choice.
Parallel 4-Link System
Air Ride Technologies also offers the 4-link rear suspension in a parallel style. Very similar in construction to the tri-link... rubber bushings, heavy tubing, laser cut brackets... but the parallel 4 link uses a panhard bar to position the rear axle side to side. In many applications, such as late model trucks, this configuration avoids interference between the upper bars and the OEM gas tank. The parallel 4 link is also slightly easier for the casual installer to visualize and install because there are fewer bar mounts to deal with... the frame brackets and axle brackets carry both upper and lower bars.
