BSB Manufacturing: Engineered for the Dirt Oval
Based in Wellington, Kansas, BSB Manufacturing has built a devoted following among dirt oval racers by doing one thing exceptionally well: engineering suspension components that help drivers get to victory lane faster. The brand is best known as the home of the BSB Black Shocks and the iconic Billet Birdcage — two products that have become benchmarks in the dirt track community for their quality and race-proven performance.
BSB Manufacturing specializes in suspension parts engineered specifically for the dirt oval track market, targeting racers who are serious about maximizing their on-track performance. Their product lineup spans a wide range of components, including springs, shock parts, and various specialized equipment purpose-built for race cars. Every part that leaves the BSB shop is designed with competition in mind — not street use, not casual weekend driving, but the demanding, high-load environment of oval dirt track racing.
A Full Suspension Solution for Dirt Track Racers
What sets BSB apart from generic parts suppliers is the depth of their suspension catalog. Racers can build out an entire rear suspension system using BSB components, from the ground up. Specializing in suspension systems, racing shocks, and other critical components, BSB products are built to withstand the extreme conditions of competitive motorsports, providing racing teams and automotive professionals with the tools they need to fine-tune their vehicles for peak performance.
The suspension control arms in the BSB lineup are engineered for the precise geometry demands of dirt oval setups, where chassis flex and bite off the corner can make or break a lap time. Complementing these are BSB’s shock mounts — available in steel bolt-on and 90-degree clevis configurations — which are designed to position the rear shock precisely and withstand the punishment of rough, abrasive dirt surfaces lap after lap.
Lateral location of the rear axle is critical in dirt oval racing, and BSB’s suspension track bars (J-Bar/Panhard bars) address this with adjustable designs featuring spherical rod ends and durable steel or aluminum construction. BSB offers adjustable J-Bar Panhard bars, aluminum Panhard frame sliders, and double-sided adjustable pinion Panhard bar brackets — giving teams a wide range of tuning options to dial in rear steer and handling balance.
For teams looking to simplify their rear suspension setup, BSB’s coilover spring and shock assemblies — including their well-regarded Outlaw Slider Coil-Over Eliminator — offer a clean, tunable solution. The BSB Outlaw Slider features state-of-the-art design in a compact package that works in tight chassis confines. Racers looking to move away from air-assisted systems can also explore BSB’s air spring to coil spring conversion kits, which simplify the suspension system and reduce maintenance between events.
Built by Racers, Trusted by Racers
The BSB team is determined to produce the highest quality shock on the market, taking a unique approach that focuses on building a shock that performs to the standards needed to win — not simply selling off-the-shelf units. That philosophy extends across their entire product line: known for their attention to detail and superior craftsmanship, BSB products offer the reliability and precision needed for every race. Whether you’re campaigning a late model, a modified, or a street stock, BSB Manufacturing has the suspension hardware to help you go fast.
