Product Details
Description
The Tuff Country 35135KN 5" Lift Kit with Radius Arm and SX8000 Shocks is a purpose-built suspension upgrade for 2014–2018 Ram 2500 4WD pickups. It delivers a confident 5-inch front lift and 3-inch rear lift, enabling larger tires while preserving ride quality and factory geometry.
- Lift Height: 5" front / 3" rear lift to create ample clearance for larger tires, specifically up to 37" x 13.5" tires.
- Radius Arm Design: Tubular, low-profile radius arms maintain factory geometry, improve ride quality, and reduce binding compared with other kits.
- Tire Compatibility: Designed to accommodate 37" x 13.5" tires with proper clearance and alignment.
- Shocks Included: SX8000 shocks are included to provide rugged damping for the lifted setup and off-road readiness.
- Hardware & Brackets: Drop Pitman arm, front & rear track bar relocation brackets, and new lower coil spring spacers help preserve alignment and steering geometry after the lift.
- Construction & Warranty: Made in the USA and backed by a limited lifetime warranty for long-term reliability.
- Installation Notes: Factory length front shocks must be replaced or extended to install properly; extended shocks may be required depending on the chosen configuration.
- Fitment & Compatibility: Intended for 2014–2018 Ram 2500 4WD models; will not fit Power Wagon models and is not compatible with factory rear air suspension.
This lift kit is a thoughtful, OEM-friendly upgrade that preserves ride quality while unlocking significant off-road capability. The tubular radius arms help maintain ground clearance and steering geometry, while the included SX8000 shocks deliver controlled damping across rough terrain. Built to withstand the demands of real-world use, the kit reflects Tuff Country’s 35+ years of suspension expertise and comes with a lifetime warranty for confidence on every mile. Ideal for truck owners seeking a reliable, high-value path to larger tires and improved approach/departure angles without compromising daily drivability.
