Track Bar

Why track bars matter on a lifted vehicle

A track bar is a rigid link running from the axle to the frame. It keeps the axle centered under the body as the suspension moves. When you lift a coil-spring vehicle, the axle drops and the factory bar pulls it off-center, so the body sits shifted over the axle and steering can wander. Installing a longer or adjustable bar, often with a relocation bracket, restores centering.

Fixed versus adjustable

• Fixed-length replacement bars: sized for a specific lift height and simple to fit.
• Adjustable bars: have a threaded end or sleeve so you can set length while mounted, which allows exact centering and fine-tuning after other changes such as tire size or lift settling.
• Forged and heavy-duty bars: use thicker tube or forged steel, often with an outside diameter around 1.25 inches or larger, for harder use.
• Bracket kits: relocate the frame or axle mount to bring the bar level and reduce the angle.

Bushings and joints

Many bars use rubber or polyurethane bushings for a quiet ride. Others use Johnny Joint style flex joints or similar articulating ends, which offer more articulation and are common in off-road builds. Heavier bushings or joints transmit more noise and vibration, but they resist deflection and deliver more precise axle control. Check whether bushings are included, and whether hardware and sleeves come in the kit.

What to check

• Front or rear position and whether it is for left-hand or right-hand drive models.
• The lift height range the bar supports, for example up to 3.5 inches or up to 6 inches.
• Whether a bracket is needed for your lift.
• Whether the bar can be adjusted while installed.

A track bar works together with the rest of the front suspension, so consider it as part of a system. A properly centered axle depends on the bar's length, its angle at ride height and the stiffness of its bushings or joints. A bar that is too short or too steep can cause bump steer, where the steering changes as the suspension moves. Aim for a bar that sits close to level at ride height and is as long as the layout allows, which reduces the sideways movement of the axle through its travel.

Inspect the mounts as well as the bar. Frame brackets and axle brackets on lifted vehicles carry large loads, and cracked welds or loose bolts are a serious problem. Some builders add gussets, but any welding on a bracket should be done carefully, as heat and poor technique can weaken it. Bushings wear out faster on heavily used vehicles, so check for play by having someone turn the steering wheel while you watch the mounts. Recheck bolt torque after the first off-road trip, and periodically after that, and have the alignment verified after any change in length.

Installation notes

Install with the vehicle at ride height, resting on its wheels, then set length so the axle is centered and the steering wheel is straight. Tighten to specification only when the suspension is loaded, and use thread locker or jam nuts as directed. A bent or loose track bar causes wandering and affects steering safety, so use a professional for installation and alignment if you are not confident. Confirm your exact year, make, model and lift, and the manufacturer's specifications.
