TJ Wrangler Suspension Kits

TJ Wrangler Suspension Kits are complete lift and suspension-upgrade packages engineered specifically for 1997–2006 Jeep Wrangler TJ models. These kits provide a bundled, fitment-correct solution for increasing ride height, improving articulation, and upgrading suspension geometry—whether you’re planning a mild lift for larger tires or building a dedicated off-road rig.To ensure a successful installation and proper setup of your new system, please consult our Instruction Manuals.

Why Choose a RockJock TJ Kit

• Chassis-specific design

Designed around the TJ/LJ suspension layout, control-arm geometry, axle width, and mounting points to ensure proper fitment and avoid the compromises of generic lift kits.

• Complete suspension upgrade

More than just lift springs— kits include adjustable, high-articulation control arms, progressive rate springs, upgraded trac bar(s), sway-bar components, and bump stops for a balanced on-road and off-road performance.

• Lift and tire clearance balance

Kits provide around 4 inches of lift, offering proper clearance for 33-inch tires and the ability to run up to 35-inch tires with minor supporting modifications.

• Improved articulation and travel

Adjustable arms, tuned springs, and high-articulation joints help maintain tire contact on uneven terrain, improving traction and off-road control.

Typical TJ Wrangler Kit Components

• Front and rear dual-rate coil springs

4-inch lift, designed to increase ride height while retaining unrivaled on-road comfort.

• Adjustable control arms

Upper and/or lower arms (depending on kit level) to correct axle position, caster, and driveline angles after lift.

• Front and rear trac bar solutions

Adjustable trac bar(s) and geometry-correction brackets to keep axles properly centered.

• Bump-stop kits

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

• Sway-bar components

Extended links and disconnect systems to improve off-road articulation while maintaining stability on the road.

• Required mounting hardware

Brackets, bolts, and related components for a complete bolt-on or near bolt-on installation.

These specialized kits can be purchased and professionally installed through an authorized shop via our Dealer Locator.

Fitment & Tire Recommendations

• 4-inch lift setups

Suitable for approximately 33-inch tires with no additional modifications.

• 35-inch tire setups

May require body lift or aftermarket high-clearance fenders depending on wheel offset, backspacing, and tire choice.

• Wheel backspacing guidance

Around 4.5 inches of backspacing is commonly recommended for typical wheel and tire combinations.

Best Use Cases

• TJ owners looking for a complete, matched suspension upgrade without piecing together parts.

• Builds that balance daily driving with trail performance, requiring both comfort and articulation.

• Drivers upgrading to larger tires who need proper suspension geometry and driveline correction.

• Enthusiasts prioritizing adjustability, durability, and long-term suspension performance.
