BSB Manufacturing Suspension Track Bar

BSB Manufacturing Suspension Track Bars for Circle Track Racing

BSB Manufacturing, headquartered in Wellington, Kansas, has spent more than two decades engineering suspension components trusted by serious circle track racers and professional chassis builders alike. Within the world of suspension track bars, BSB has earned a reputation for producing Panhard bars and J-bars that deliver precise rear axle location and repeatable handling — qualities that matter every lap on a dirt oval.

The Role of a Track Bar (Panhard Bar) in Circle Track Suspension

A suspension track bar — often called a Panhard bar or J-bar in circle track applications — is a lateral link that connects the rear axle housing to the chassis. Its primary job is to control side-to-side movement of the rear axle relative to the frame. On a circle track car, even small changes in track bar height and length can dramatically shift the rear roll center, altering how the car rotates into and off corners. Getting this geometry right is one of the most impactful tuning adjustments a crew can make.

BSB J-Bar and XD Series Panhard Bars

BSB Manufacturing offers two primary track bar lines tailored to circle track applications:

• Standard J-Bar Series: BSB's classic adjustable Panhard bar, available in multiple length ranges (such as 18‑3/4 to 21‑1/2 inches and 20 to 22‑3/4 inches). These bars feature a J-style design, spherical rod ends for precise articulation, steel construction, and a durable black powder coat finish — making them a proven staple for dirt oval competitors.
• XD Series J-Bar: BSB's upgraded heavy-duty line, the XD Series Panhard bars share the same adjustable, J-style architecture as the standard bars but are built to handle the increased stress demands of higher-powered or more aggressive race applications. Like the standard series, they utilize spherical rod ends and come finished in black powder coat.

Both series are designed as universal fitments, making them compatible across a wide range of circle track chassis setups. The adjustability built into each bar allows teams to fine-tune rear roll center height without swapping hardware — a critical advantage when conditions change between hot laps and feature events.

Why Choose BSB for Your Track Bar Needs?

BSB Manufacturing is not a warehouse operation — they are a dedicated manufacturer. Every component goes through a focused production process aimed at consistency and durability under race conditions. Their track bars are the same components trusted by major chassis builders who spec BSB parts from the ground up, which speaks to the quality expected at the top levels of grassroots oval racing. For racers who demand reliable rear axle location and repeatable corner entry behavior, BSB's Panhard bar lineup is a well-proven choice.
