Five Star Fabricating Rocker Panels: Race-Proven Side Panel Solutions

When it comes to circle track racing, every component on the car has a job to do — and rocker panels are no exception. Five Star Fabricating has spent decades engineering race car body components that balance durability, aerodynamic efficiency, and ease of installation, and their rocker panel lineup reflects all of that hard-won expertise.

The MD3 Rocker Panel System

The centerpiece of Five Star Fabricating's rocker panel offerings is the MD3 Rocker Panel line — an interconnecting modular system purpose-built for dirt late model and dirt modified applications. These aren't generic body pieces. As interconnecting components, they are designed to work together seamlessly, creating a continuous side profile that manages airflow and adds lateral rigidity to the chassis.

Five Star's MD3 rocker panels are constructed from high-impact plastic that is engineered to hold up under the punishing conditions of short-track and dirt oval racing. The material resists cracking and deformation from debris, curb strikes, and the inevitable door-to-door contact that defines these racing disciplines — all while keeping weight to a minimum.

How the MD3 System Is Configured

A complete MD3 rocker panel setup requires three panels per side. One full rocker panel mounts between the front and rear wheel flares, while a half-piece installs behind the rear wheel flare to finish out the body line. This modular approach means racers can replace individual sections after contact without swapping out an entire body side — a practical advantage when turnaround time between races matters.

The MD3 rocker panels fit most circle track cars, making them a versatile choice for a wide range of chassis configurations in both dirt and pavement oval competition. For racers who want to match team colors or sponsor liveries, the panels are available in nearly a dozen color options straight from the factory.

Aluminum Rocker Panels

For builders and teams who prefer metal construction, Five Star Fabricating also offers aluminum rocker panels (such as part FIV000-5500A-B) as an alternative to the plastic variants. Aluminum panels offer a different balance of rigidity and repairability that suits certain classes and rulebooks, and they carry the same attention to fitment and finish that defines the Five Star lineup.

A Brand Built for the Track

Five Star Fabricating — operating under the well-known Five Star Race Car Bodies banner — has been producing race car body components since the late 1970s, growing from a small Wisconsin operation into a trusted NASCAR Competition Partner. Their rocker panels sit within a broader ecosystem of body panels that includes noses, fenders, roofs, and aero valances, all engineered to work together as a cohesive aerodynamic package. Whether you're building a weekend-warrior dirt modified or maintaining a competitive late model program, Five Star's rocker panels deliver the fit, material quality, and color selection that serious racers depend on.
