MPD Racing Differential Shifter Cable

MPD Racing Differential Shifter Cables for Sprint Cars and Midgets

When reliability matters most — at full throttle, on a dirt oval, with a race on the line — the connection between your shifter and differential has to be flawless. MPD Racing has been engineering precision race components for over 30 years, and their differential shifter cables carry that same commitment to quality into one of the most mechanically critical links on your car.

Engineered for the Demands of Open-Wheel Racing

MPD Racing's shifter cable lineup is purpose-built for the sprint car and midget car environment. The flagship offering — part number MPD84020 — is a 44-inch steel cable with a plastic liner, a construction spec chosen specifically for sprint car and midget applications. The steel inner cable delivers the tensile strength needed to actuate a rear differential under race loads, while the plastic liner reduces friction and keeps cable travel smooth and consistent, even when the car is flexing over rough track surfaces.

The 44-inch length is intentionally sized to suit the typical chassis geometry found on sprint cars and midgets, reducing the need for custom routing or adapters. Every dimension in MPD's component designs reflects decades of real-world racing feedback — not catalog spec sheets.

A Brand Built on Track-Side Credibility

MPD Racing was founded with a straightforward mission: build the best race components available in the United States. The company sources its materials domestically and manufactures its parts in-house, maintaining tight control over tolerances and quality. That approach has made MPD a trusted name across circle track disciplines including sprint car, midget, and vintage open-wheel racing.

Their differential shifter cables are designed to integrate cleanly with MPD's broader shifter ecosystem — including their well-regarded Positive Camlock shifter assembly — so racers can build a cohesive, matched system rather than mixing and matching incompatible components. The cable's pre-formed ends ensure a secure connection to the shifter mechanism, while the durable outer liner protects the inner cable from debris, heat, and abrasion common in dirt track environments.

What to Know When Selecting a Differential Shifter Cable

Choosing the right differential shifter cable means matching cable length to your chassis layout, ensuring the liner material suits your operating conditions, and confirming end compatibility with your specific shifter assembly. MPD's sprint car cable at 44 inches accommodates most standard sprint and midget layouts, but it's always worth measuring your routing path before ordering. Racers running MPD's Positive Camlock or Push Lock shifter assemblies will find this cable is engineered to work directly with those systems.

For open-wheel racers who demand USA-made components backed by a manufacturer with a genuine racing heritage, MPD Racing's differential shifter cable represents a precise, purpose-driven choice.
