122321 Radius Arm Upgrade Kit DODGE / RAM 3500 PICKUP 4WD 2"-4" FRONT 13-19

Product Description:

3" Radius Arm Systems for RAM 3500 4WD trucks, BDS has packaged the new arms as a stand alone radius arm upgrade available for late model RAM 3500 and RAM 2500 trucks. These arms are designed to correct the suspension geometry when used with 2-4" of lift kits.


These massive radius arms are built to handle the use and abuse RAM 2500/3500 owners demand and far surpass the factory stamped steel arms with thick wall tubing and support gussets. The arms are formed inward to allow for addition tire clearance of oversized tires and incorporate factory style 3-1/4" rubber bushings to minimize road vibrations while allowing for long, maintenance-free bushing life. The new radius arms are designed as a direct bolt-in replacement for the factory radius arms allowing for quick and straight forward installation.


To maintain factory alignment adjustability OE eccentric adjusters are supplied with the arms and install using OEM hardware. The arms come finished in a durable textured black powder coat finish with a copper BDS nameplate.

These new radius arms are a great addition for RAMs running the 2" leveling kit. They should not be used in conjunction 4" radius arm drop bracket kits, but are a great addition to improve the performance over the factory arms when used with the 6" radius arm drop bracket kits.

  • High strength 1/4" steel construction, internally gussets, fully boxed and welded.
  • Lower cam slot and cam washers allow for caster correction.
  • Finished in a durable textured black powercoat.
  • Includes BDS Suspension badging.
