Laser cut and CNC bent.125 4130 chromoly plate steel precision construction creates an incredibly strong package engineered to be used on trucks with 0"-8" of lift. The critical pivot points are maintenance-free and extremely durable for long-lasting use.

Our 1-ton spring loaded HD series ball joints maintain the factory driving experience and can take a beating from the excessive weight of heavy aftermarket wheels and tires. To protect the joint from nasty road debris such as salt and sand, our arms include CNC machined billet aluminum caps which helps extend the life of the ball joints. Frame side pivots feature our proprietary new TCT bushings which are self-lubricating and engineered to last.

These new bushing include "side biter" washers to aid in maintaining alignment settings. The free-floating bushing design eliminates friction which is the most common culprit of traditional bushing failure.
