Clayton Off Road Custom Front Adjustable Track Bar Builder Kit 2.0 Lower for Jeep XJ ZJ TJ LJ High-Steer

Is This for You?

• You're running a high-steer conversion on your XJ, ZJ, TJ, or LJ and need a front track bar with a wider axle-end joint for increased lateral load capacity — the 2.0" axle-end Johnny Joint provides a larger body and wider contact surface than the 1.6" version (COR-4500340), suited for heavier builds or applications where the axle-end bracket spacing requires a 2.0" width joint.
• You need a wider final length range than the 1.6" lower kit provides — this kit's final length range is 29-13/16" to 35-11/16", nearly 4" longer than the COR-4500340's 31-11/16" maximum, covering a broader range of axle positions, lift heights, and bracket locations across XJ, ZJ, TJ, and LJ builds.
• You're building a custom front suspension setup and a bolt-on track bar won't work for your specific bracket location or steering geometry — the 24" unfinished DOM tube ships ready to cut and weld to your exact required length within the final range.

The Result

• 2.0" forged Johnny Joint at the axle end (2.0" width, 1/2" thru-bolt, RH thread) — larger body than the 1.6" version for increased lateral load capacity and wider bracket spacing compatibility.
• 2.5" forged Johnny Joint at the frame end (2.625" width, 9/16" thru-bolt, RH thread) — same high-load frame-end spec as COR-4500340, greaseable and rebuildable.
• 1.5" x 0.156" wall DOM tube at 24" unfinished — wider final length range of 29-13/16" to 35-11/16" covers more platform and lift height combinations than the 1.6" lower kit.

The COR-4500300 is Clayton Off Road's custom front adjustable track bar builder kit with a 2.0" axle-end Johnny Joint, designed for solid-axle Jeep platforms (XJ, ZJ, TJ, LJ) running high-steer conversions or custom front suspension geometry. The primary difference from the COR-4500340 (1.6" lower) is the axle-end joint: this kit uses a 2.0" forged Johnny Joint with a 2.0" body width and 1/2" thru-bolt, compared to the 1.6" joint's narrower 1.6" width and 9/16" thru-bolt. The 2.0" joint provides a larger articulation envelope and is suited for applications where the axle-end bracket spacing or load requirements exceed what the 1.6" joint is designed for. The final length range is also wider at 29-13/16" to 35-11/16" center-to-center — nearly 4" more maximum length than the COR-4500340 — covering a broader range of axle positions, lift heights, and custom bracket locations across all four platforms. The frame-end joint is identical to the COR-4500340: a 2.5" forged Johnny Joint with 2.625" body width and 9/16" thru-bolt. Both joints are RH thread for double-adjustable length tuning and are greaseable and rebuildable. The 24" unfinished DOM tube (1.5" OD, 0.156" wall) is cut to the required length and welded to final dimension by the fabricator. Compatible with 1/4" brackets at both ends. Made in the USA.

Installation & Fabrication Notes

• Fabrication required. The 24" DOM tube must be cut to your required length and welded to final dimension. This is not a bolt-on track bar.
• Verify your axle-end bracket uses a 1/2" thru-bolt — this kit's axle-end joint uses a 1/2" thru-bolt, not the 9/16" used in COR-4500340. Using the wrong bolt diameter will result in improper joint retention.
• Determine your required center-to-center length before cutting — final range is 29-13/16" to 35-11/16".
• Verify 1/4" bracket thickness at both frame and axle mount before installation.
• Grease both Johnny Joints at the zerk fittings before first use and at regular service intervals.
• After installation, verify full steering sweep from lock to lock with no contact between the axle-end joint and the high-steer knuckle or tie rod.
• Set track bar length with the axle centered under the vehicle at ride height.
• Torque frame-end 9/16" thru-bolt and axle-end 1/2" thru-bolt to your specific bracket specification.

Wheel & Tire Fitment

Compatible with standard XJ/ZJ/TJ/LJ wheel and tire combinations. Track bar length and axle centering affect tire clearance at full steering lock — verify clearance after installation with your specific tire size and lift height.

Engineering Question: Have you confirmed whether you need the 2.0" axle-end joint (this kit, COR-4500300) or the 1.6" axle-end joint (COR-4500340)? Key differences: axle-end bolt size (1/2" here vs. 9/16" on COR-4500340), joint width (2.0" vs. 1.6"), and maximum final length (35-11/16" vs. 31-11/16"). Verify your axle bracket bolt hole diameter and required final length before ordering.
