4.86 Mod Rear w/o Tubes Saturday Night Special

This rear axle center section from the Saturday Night Special line runs a 4.86 gear ratio and ships without axle tubes. Built for dirt track and oval racing, it lets teams swap gear sets quickly to match changing track conditions. Racers who need a lightweight center section for a custom rear-end build will find a lot to like here.

A magnesium center section keeps unsprung weight low compared to steel or aluminum housings. That lighter mass helps the unit hold up under the heat and stress that come with pro-level racing. Professional chassis builders and race teams can add their own axle tubes and internal parts, getting a setup tuned to their exact needs.

Standard quick-change gear sets work with this center section, so you can fine-tune your final drive ratio right at the track. It delivers the torque multiplication short-track racers need and holds up as a top-tier choice for competitive rear axle builds.
