Product Details
Description
Elevate your 2003–2007 Dodge Ram 2500/3500 4WD with confidence using the Tuff Country 34003KN 4.5" Lift Kit. Built for truck enthusiasts who want bigger tires and enhanced off-road capability without sacrificing everyday ride quality, this bolt-on system blends rugged engineering with practical, street-friendly performance.
- Lift height: 4.5" front lift with a 2" rear drop to level the stance and accommodate up to 36" x 12.5" tires.
- Shocks included: Tuff Country SX8000 nitro gas shocks deliver consistent damping and durable performance across trails and highways.
- Control arms: Includes upper and lower control arms to maintain proper alignment and predictable handling after installation.
- Coil spring spacers: Upper spacers help retain a factory-like ride while boosting clearance for larger tires.
- Rear axle tube compatibility: Fits both 3.5" and 4" rear axle tubes for versatile installation across compatible Rams.
- New components: Includes a new track bar bracket and a pitman arm to optimize steering geometry and tracking.
- Rear hardware: Recessed rear blocks and mounting hardware complete the lift with solid, reliable support.
- Finish: Powder-coated components resist corrosion and stand up to off-road use.
- Installation: Bolt-on design with all required parts included for a straightforward upgrade.
- Warranty: Backed by Tuff Country’s limited lifetime warranty for long-term confidence.
- Fitment notes: Designed for 2003–2007 Dodge Ram 2500/3500 4WD; not compatible with Off-Roadster models that come from the factory with a lift. Some 2-piece rear driveshaft configurations may require a carrier bearing drop (part #20824D).
This kit enables a confident, balanced stance with room for larger tires, improved ground clearance, and enhanced on- and off-road performance. The included SX8000 shocks and coil spacers help preserve a comfortable daily ride while delivering the rugged capability you expect from a 4.5" lift. With precision-engineered upper and lower control arms, a pitman arm, and a new track bar bracket, steering and alignment stay predictable as you explore tougher terrain. Built with durable, powder-coated components and backed by a lifetime warranty, this Tuff Country lift kit is a reliable, value-driven upgrade for enthusiasts who demand real capability without compromise.
