Performance Overview

Take your RAM 3500 to new heights with the BDS 1682H 6” Radius Arm Lift Kit, designed to elevate both appearance and capability. This comprehensive system supports up to 37” tires and delivers increased articulation, improved ride comfort, and rugged durability for serious off-road use.

The included diesel-specific Pro-Ride coil springs provide a smooth, predictable ride while maintaining proper suspension geometry. HD radius arms replace the weak factory stamped units with beefy tubular construction, adjustable caster cams, and service-free OE-style bushings.

Steering & Driveline Correction

To ensure optimal steering feel and factory-like alignment:

• The forged drop pitman arm reduces steering linkage angles.

• A track bar drop bracket maintains geometry and re-centers the axle through the full range of motion.

• The transfer case indexing ring and HD crossmember correct the front driveline angle, critical for 6" lifts, while retaining use of factory driveshafts.

Rear Suspension

In the rear, the kit includes:

• High-strength steel lift blocks

• Extended u-bolts

• Precision-matched NX2 Nitro or FOX 2.0 shocks
  This setup provides a level ride and full suspension functionality without affecting payload capability.
