Product Details
Description
Upgrade your Ram 2500/3500 4WD with the Tuff Country 36217KN 6" Long Arm Lift Kit — a purpose-built suspension upgrade designed for off-road enthusiasts who want noticeable height, improved ride quality, and the ability to run larger tires without compromising handling.
- Lift configuration: 6" front lift with a 4" rear drop for a balanced stance and enhanced ground clearance.
- Long-arm suspension design: Increased articulation for rockier terrain and smoother travel over uneven surfaces.
- Includes SX8000 shocks: Nitro-gas shocks deliver consistent damping and improved control under load and after impacts.
- Coil springs and rear blocks: Strong, durable springs and rear blocks engineered for stability and load handling.
- Greasable and rebuildable flex joints: Reduce suspension binding and extend component life with serviceable joints.
- All required hardware for bolt-on installation: Simplified, straightforward installation with included brackets, mounts, and fasteners.
- Pitman arm and track bar relocation brackets included: Maintains steering geometry and alignment after lifting.
- Fits 3.5" or 4" rear axle tubes: Rear block compatibility designed to accommodate common Ram axle configurations.
- Allows use of up to 37" x 12.5" tires: Broad tire compatibility for significant off-road capability without trimming.
- Vehicle compatibility and notes: Designed for 2003–2007 Ram 2500/3500 4WD; not intended for Off-Roadster factory-lift variants; some setups may require carrier bearing drop for 2-piece rear driveshafts.
- Limited Lifetime Warranty: Tuff Country stands behind this lift kit with lasting confidence in its durability.
This kit is built to deliver a dramatic improvement in ride quality and handling while expanding your vehicle’s off-road capability. With a robust long-arm design, adjustable articulation, and included high-performance SX8000 shocks, you’ll notice better control on rough trails and more confidence during highway transitions. The combination of coil springs, rear blocks, and greaseable joints is engineered for reliability, easy serviceability, and long-term value—backed by Tuff Country’s decades of suspension expertise.
