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.
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.
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.
