Poly Performance
The Synergy Stage 3 Suspension System features front track-bar relocation bracket, draglink flip kit, rear track-bar relocation bracket, and adjustable upper and lower control arms. The lower control arms are manufactured from high-quality crush resistant 1 3/4 x 0.188-inchwall 1026 DOM tubing. The control arms use Currie Enterprises Johnny Joints for performance and durability. OEM style rubber bushings are also used in the control-arm assemblies to minimize road vibration. The control arms and drag link use double adjuster-sleeve and pinch-bolt assembly, which allow for easy adjustment without removal. Also included in the kit are a sway-bar disconnect system, progressive-wound coil springs, and front and rear track-bar relocation brackets. These move the track-bar mounting position thus increasing suspension roll-center height, which improves handling on and off road. Them system is completely bolt-on.
