Product Details
Description
Upgrade your Dodge Ram 2500/3500 4WD with the Tuff Country 34021KN 4.5" Lift Kit, a bolt-on suspension upgrade designed for durability, straightforward installation, and confident off-road performance. Specifically engineered for 2007–2008 Ram 2500/3500 4WD models, this kit adds significant ground clearance while preserving ride quality.
- Lift height: 4.5" suspension lift designed for 2007–2008 Ram 2500/3500 4WD, providing a solid, capable stance.
- Complete, bolt‑on system: Includes upper and lower control arms, coil spring spacers, rear blocks, SX8000 nitro gas shocks, pitman arm, new track bar bracket, and all mounting hardware for a plug‑in installation.
- Shocks: SX8000 nitro gas shocks ensure improved dampening and ride quality across challenging terrain.
- Control arms: Upper and lower control arms are included to help maintain proper alignment after lifting for stable handling.
- Rear axle compatibility: Rear blocks and spacers fit both 3.5" and 4" rear axle tubes for flexible, precise fitment.
- Finish and durability: Powder-coated components resist corrosion and stand up to off-road exposure.
- Tire compatibility: Designed to accommodate up to 36" x 12.5" tires when paired with the appropriate wheels (kit references to support 36x12.5" tires).
- Warranty: Backed by Tuff Country’s limited lifetime warranty for long-term reliability.
- Notes on installation: Bolt-on installation with minimal custom work required; for 2-piece rear driveshaft setups, carrier bearing drop may be needed (see installation notes).
- Vehicle compatibility: Fits 2007–2008 Dodge Ram 2500/3500 4WD; not compatible with Off-Roadster models that come with a factory lift.
With this kit, you gain more ground clearance for rugged trails, the ability to run larger tires, and a balanced stance that improves approach and departure angles. The included control arms help preserve steering feel and alignment, while the SX8000 shocks provide dependable dampening on both highway and dirt roads. The bolt‑on design and powder‑coated hardware deliver a durable upgrade you can trust for daily driving and weekend adventures, backed by a long-standing brand commitment from Tuff Country.
