• Front and rear dual-rate coil springs

4-inch lift, increasing ride height while keeping ride quality manageable for daily or mixed use.

• Adjustable control arms (front and rear)

Used to correct axle position, caster, and driveline angles after lift, while improving articulation and durability.

• Front and rear trac bar solutions

Adjustable trac bars and/or geometry-correcting brackets to re-center axles and maintain proper suspension alignment.

• Bump-stop kits

Front and rear bump stops to control suspension travel and prevent bottoming out under load or during off-road impacts.

• Sway-bar components

Extended links and disconnect-style solutions that allow increased articulation off-road while preserving on-road stability.

• Required mounting hardware

Brackets, bolts, and related components for a near plug-and-play installation (shocks sold separately).

Fitment & Tire Recommendations

• Vehicle fitment

Designed specifically for 2004–2006 Jeep Wrangler Unlimited (LJ).

• Tire size guidance

With a full 4-inch lift and proper wheel setup, tire sizes up to approximately 35 inches are commonly supported, sometimes requiring a body lift or high-clearance aftermarket fenders.

• Wheel and backspacing considerations

Proper wheel offset and backspacing are important to avoid interference; always confirm wheel and tire specs with suspension and fender clearance.

Best Use Cases

• LJ Unlimited owners seeking a complete, fitment-correct suspension upgrade.

• Builds focused on larger tires, improved ground clearance, and better off-road articulation.

• Drivers wanting a balanced setup suitable for daily driving and trail use.

• Off-road, rock-crawling, or overland builds that require durability, articulation, and corrected suspension geometry.
