Glide-Ride Leaf Springs

Built to outperform, BDS engineered the Glide-Ride leaf springs into a multi-leaf progressive spring rate design that provides a smooth ride with any load. This is accomplished with an exclusive triple-stage leaf spring design. Upgrading to BDS Glide-Ride leaf springs will provide flexibility throughout the suspension cycle.

Steering Correction

To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.

Front U-Bolt Type

This vehicle was manufactured with either square front U-Bolts or radiused front U-bolts. Typically, 1999-2000 are square and 2001-2004 are radiused, but that is not always the case. The radiused U-bolts aren't square or round, but rather have a gentle radius that matches a cast factory upper U-bolt plate on top of the factory spring. Vehicles manufactured prior to 2-28-99 require yet another different box kit due to a change in the factory track bar. Please make the appropriate selection for your particular vehicle.

Rear Lift Option

Select rear box kit based on whether or not your RAM has factory Rear Overload Leaf.
