Product Details
Description
Upgrade your Ram 2500 or 3500 with a purpose-built suspension system that enhances off-road capability without sacrificing everyday drive quality. The Tuff Country 34222KN 4.5" Long Arm Lift Kit with SX8000 Shocks is a bolt-on solution designed for 2009–2013 Ram 2500 4WD and 2009–2012 Ram 3500 4WD, providing solid elevation, improved handling, and tire-ready clearance.
- Lift height: 4.5" front lift and 2" rear lift for a balanced, rugged stance that accommodates larger tires
- Long-arm suspension: Heavy-duty black tubular control arms deliver greater articulation and smoother on- and off-road performance
- Shocks included: Tuff Country SX8000 nitro-gas shocks for improved damping and consistent ride quality
- Coil spring spacers: Integrated spacers help achieve the desired height while maintaining spring preload
- Greaseable & rebuildable joints: Flex joints reduce suspension binding and extend longevity with serviceable design
- Rear axle compatibility: Compatible with 3.5" or 4" rear axle tubes and includes rear blocks for proper alignment
- Bolt-on installation: Designed for straightforward, no-wuss install with included brackets and hardware
- Relocation brackets: Pitman arm and track bar relocation brackets maintain correct geometry after the lift
- Warranty: Limited lifetime warranty reflects Tuff Country’s 35+ years of suspension expertise
- Fitment notes: Not compatible with Off-Roadster models; carrier bearing drop may be needed if your vehicle has a two-piece rear driveshaft
- Tire clearance: Supports up to 36" x 12.5" tires for enhanced ground clearance and aggressive traction
- Upgrade kit compatibility: Designed to integrate with other Tuff Country lift systems and a variety of other manufacturers’ lifts
This kit translates into real-world benefits: a more confident on- and off-road ride, improved steering feel with reduced bump steer, and the ability to tackle rough trails with larger, more capable tires. The long-arm design minimizes binding and maximizes wheel travel, while the included SX8000 shocks provide reliable damping through challenging terrain. Built with durability in mind, the system uses greasable joints and rugged components to stand up to repeated use, and the bolt-on installation keeps the project approachable for do-it-yourself enthusiasts. With a trusted lifetime warranty, you’re investing in a suspension upgrade that’s designed to perform and endure as your Ram evolves from daily driver to weekend standout.
