This kit includes 2 components, each built and powder-coated in-house.
Enhanced Stability and Control
Take your Jeep Wrangler TJ or LJ (1997-2006) to the next level with the Crawl Series Track Bar Kit—a crucial upgrade for any solid axle suspension system.
Designed for unmatched stability, axle centering, and superior handling, this kit includes both front and rear adjustable track bars, ensuring your suspension remains dialed in whether you're on rugged trails or daily commutes.
By keeping your axles properly aligned, this kit helps eliminate death wobble, improves steering response, and reduces suspension stress, making it essential for any lifted Jeep.
Key Features Benefits
- Unmatched Axle Stability Handling – Proper axle alignment is essential for maintaining steering precision and suspension integrity. Our track bars eliminate side-to-side axle movement, reducing steering wander and body roll for a smoother, more controlled driving experience—on or off the road.
- Heavy-Duty DOM Tubing Construction – Both track bars are crafted from 1.5" OD 5/16” wall DOM tubing, significantly stronger than factory track bars. This ensures maximum durability, impact resistance, and long-term reliability, even under extreme off-road abuse.
- RockJock Johnny Joints for Extreme Flexibility – Featuring Johnny Joints at both ends, these track bars provide unmatched articulation, allowing your suspension to move freely while maintaining axle alignment. This dramatically enhances off-road performance by preventing binding and limiting restrictions in high-flex scenarios.
Perfect Fit for Lifted Jeeps
When lifting your TJ or LJ, the axles shift laterally, impacting alignment and suspension geometry. Our adjustable track bars correct this issue, re-centering the axle for better drivability, reduced tire wear, and improved suspension function.
- For 0 to 3-inch lifts, the rear track bar is a direct bolt-in upgrade.
- For 3+ inch lifts, or vehicles with an SYE, a corrected rear axle mount is required due to the steeper pinion angle rotation and clearance issues between the bar and the factory mount. We offer the mount that works best with our kit as a selectable option above.
Two-Stage Powder Coating
Every track bar undergoes a two-stage powder coating process for extreme durability and corrosion resistance. Zinc primer base coat prevents rust. Durable top coat, available in 10 color options, adds a customized look while providing additional protection against harsh elements.
Made in the USA
Proudly manufactured in Orem, UT, the Crawl Series Track Bar Kit reflects the highest standards of American craftsmanship.
By sourcing high-quality materials locally and maintaining strict in-house quality control, we ensure superior reliability, longevity, and performance.
Optional Hardware Upgrade
The Crawl Series Track Bar Kit is designed for straightforward installation using factory hardware.
However, the front track bar requires drilling the frame mount for installation—a drill bit and all necessary mounting hardware are included.
For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits for an even smoother install.
With its heavy-duty construction, Johnny Joint flexibility, and full adjustability, this kit ensures superior performance in all conditions.
