It’s designed to give you real visual impact and real off-road capability without sacrificing comfort on paved roads.

What you get

• Front and rear lifted leaf springs engineered to deliver reliable ride height and durability under load
• Sway bar drop brackets and a track bar bracket to maintain optimal suspension geometry and a factory-like ride after lifting
• Rough Country premium N3 shocks with 10-stage variable high-pressure nitrogen charging for a balanced blend of off-road articulation and highway smoothness
• Upgrade-ready components that fit up to 37" tires with proper wheel backspacing

Why this lift stands out

This system isn’t just about a bigger tire; it’s about maintaining control and comfort with a taller stance. The front-for-rear leveling preserves steering feel and ensures predictable handling, so you can tackle rough trails or gravel roads with confidence. The integrated sway bar drop brackets and track bar bracket optimize geometry, helping you keep alignment angles close to stock even after the lift. That means you enjoy a steadier highway ride and confident cornering without the chatter or clunk of a setup that neglects steering geometry.

Ride quality and performance you can feel

• N3 shocks deliver a refined highway ride while soaking up whoops and ruts off-road, thanks to a durable 18mm spring-loaded piston rod and a 54mm shock body for improved cooling and longevity.
• 10-stage adjustment compatible with varying terrains, giving you the flexibility to dial in the feel you want—whether you’re cruising to the trailhead or carving through backcountry trails.
