Reid Racing

About Reid Racing

Born from decades of motorsports expertise, Reid Racing is an American manufacturer with deep roots in both drag racing and off-road competition. Reid Racing was founded in 2006 as a spin-off of the legendary Dedenbear Products, Inc. — the company credited with inventing the Delay Box that became standard protocol in bracket racing. Founders Dennis and Debra Reid carried that tradition of precision engineering into a new venture focused squarely on high-performance transmission and drivetrain components.

From its California base, Reid Racing designs and manufactures every product with one goal in mind: building parts that outlast and outperform the stock components they replace. The brand serves two distinct but equally demanding communities — the drag racer chasing every fraction of a second down the quarter mile, and the 4x4 enthusiast pushing their rig to its limits on rock crawls and desert trails.

Signature Products & Innovation

Reid Racing built its reputation on the Superglide transmission case — a reimagined Powerglide platform engineered to handle the extreme torque and shock loads of high-horsepower drag applications. That same philosophy has since expanded into the Super Hydra 400 (SH400) and Super 80 (4L80E) case platforms, each redesigned from the ground up with strengthened internals, SFI 4.1 certification, and features like heli-coiled threads and pre-machined pressure tap ports. These aren't just upgraded versions of factory castings — they are purpose-built racing components made in the USA.

On the off-road side, Reid Racing's steering knuckle kits have become a go-to upgrade for Jeep and truck builders seeking genuine durability gains. Engineered for popular axle configurations including the Dana 44 and Dana 60, these heavy-duty iron knuckles are finished in Reid's signature orange powder coat and are designed to handle the punishing lateral loads generated by aggressive off-road driving and oversized tires.

For builders upgrading their automatic drivetrain, Reid's automatic transmission extension housings complement their case lineup with the same commitment to strength and fitment precision. These tailshaft housings are engineered to pair seamlessly with Reid's transmission cases and are built to handle the torque demands of modified and high-output powerplants.
