Product Details
Description
The Tuff Country 36213KN 6" Long Arm Lift Kit is a rugged, bolt-on suspension upgrade designed for 2003–2007 Dodge Ram 2500/3500 4WD. With a 6" lift up front and a 4" lift in the rear, it opens room for larger tires and improved off-road capability, while keeping on-road stability in check.

- Shocks Included: SX6000 nitrogen-style shocks provide controlled damping for improved ride quality and handling.
- Drop Pitman Arm Included: Maintains steering geometry and helps reduce bump steer after lifting.
- Track Bar Relocation Bracket: Preserves steering alignment with the lifted stance.
- Coil Spring Spacers & Rear Blocks: Maintains proper ride height and suspension geometry.
- Greasable & Rebuildable Flex Joints: Reduces suspension binding and extends component life.
- Finish & Construction: Black powder-coated steel for durability and corrosion resistance.
- installation Notes: Simple bolt-on installation; some 2-piece rear driveshaft configurations may require carrier bearing drop (#20824D).
- Warranty: Backed by a limited lifetime warranty for long-term peace of mind.
- Vehicle Fitment: Specifically designed for 2003–2007 Dodge Ram 2500/3500 4WD. Not compatible with Off-Roadster models that come with a factory lift.
Benefits
Expect a more aggressive stance and improved approach/departure angles without sacrificing daily drivability. The long-arm design delivers smoother, more controlled wheel travel across rocky trails, while the SX6000 shocks provide confident damping on both highway and off-road surfaces. Enhanced steering geometry and reduced bump steer translate to more predictable handling at high angles, and greaseable joints minimize suspension binding for a smoother ride over time. With Tuff Country’s limited lifetime warranty, this lift kit offers reliable performance and long-term value for serious off-road enthusiasts.
