Strong parts are always good. The Synergy JK features a Currie Rock Jock 60 frontend with Superior 4340 35-spline axles, CTM U-joints, 5.38 gears, and an Eaton Detroit Locker. Custom 4130 tie rod and drag link are strong and the PSC hydraulic ram assist system makes it easy to steer the big 41.5-inch Pit Bull tires. A Synergy adjustable track bar can be adjusted on the vehicle, making dialing-in simple. Note the Synergy swaybar skid that’s an option with their front bumper.
