Control Freak Suspensions' 4-Link Coil-Over Rear Suspension Systems for AMC muscle cars are designed to provide exceptional traction, stability, handling, control, safety and performance, making your AMC muscle car a contender. This weld-in system is designed in-house on the most advanced SolidWorks CAD systems. These 4-link systems are eager performers that release unsprung weight while increasing the torsional rigidity of the rear end. Wheel hop is eliminated and rear body roll is controlled. Lighter, stronger and more precise than the stock suspension, these systems are as much at home on the street as they are on the strip, autocross or road race courses. All of our 4-link coil over systems come to you packaged and complete. It just doesn’t get any better than that.

On triangulated systems, one set of trailing arms, either the upper or lower, are angled inward creating a triangle.  No panhard bar is required for these systems because the triangle prevents the system from moving side-to-side.Your 4-link coil-over system comes complete, but all brackets must be welded into position. Here’s what you get, so there’s nothing else to buy.
