4-inch Suspension Lift S Lift Kit

The Rough Country 4-inch Suspension Lift Kit for Jeep Wrangler YJ (1987–1995) is engineered for off-road enthusiasts and daily drivers who demand increased ground clearance, improved approach angles, and enhanced articulation. This lift system replaces factory suspension geometry with a complete assembly designed to raise the frame four inches while maintaining ride quality and load-carrying capacity. Whether you're tackling rocky trails, fording water crossings, or simply wanting better sight lines on the highway, this kit addresses the core limitations of stock YJ geometry.

The 4-inch Suspension Lift Kit includes precision-engineered brackets, OEM-spec bushings, grade-8 hardware, progressive-rate leaf springs, and calibrated shock absorbers—each component working in concert to distribute load evenly and prevent binding at full articulation. Rough Country's leaf spring design maintains the YJ's proven leaf-spring architecture while extending spring rate to handle the increased height without sagging under load. The included shocks feature velocity-sensitive valving, which adapts to both slow rock-crawling speeds and highway driving, ensuring predictable damping across all conditions. All hardware is stainless or zinc-plated to resist corrosion in harsh environments.

Installation requires basic mechanical skill, a lift or jack, and standard hand tools; most builds take 6–10 hours. The YJ platform benefits significantly from this lift due to its solid-axle architecture and tight wheel wells—the additional four inches opens tire options up to 33 inches and improves breakover and departure angles without requiring frame notching. This kit is compatible exclusively with 1987–1995 Jeep Wrangler YJ models and does not fit newer TJ or JK platforms. Proper wheel alignment is essential after installation to ensure even tire wear and steering feel.
