The Air4Link 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 leafsprings. It requires some welding, but it is a simple and very effective way to upgrade your vintage suspension.

The Air4Link can be equiped with a RideTech air suspension system or coilover by using our cross member kit. The Air4Link comes in two designs, triangulated and parallel, each with their own advantages. To read more about the differences of these two designs check our tech page.

Features and Benefits of the Air4Link
» Superior ride quality
» Simple, straightforward installation
» Rubber bushings eliminate poly-bushing squeak & improve ride quality
» .219" wall direct threaded DOM tubing for maximum strength
» Allows maximum suspension travel and tighter wheel to fender clearances
» .188" wall alloy steel brackets are CNC lasercut for strength and accuracy

 

Air4Link Products and Components:


Weld-in Air4Link- Parallel

Part #: 18988899 / 18988999

$550.00
Ridetech offers the 4 link rear suspension in a parallel style. Very similar in construction to the tri link but the parallel 4 link uses a panhard bar to position the rear axle side to side.
 

Weld-in Air4Link - Triangulated

Part #: 18987999 / 18988099

$450.00

Ridetech offers the 4 link rear suspension in a triangulated style. Very similar in construction to the parallel 4 link but the uppers bars are placed at an angle to the lowers. When connected securely to the axle and the frame they form a “triangle” which keeps the rear axle centered under the vehicle.
