Borgeson Steering Gear Box

Borgeson Steering Gear Boxes: Modern Quick-Ratio Performance

When it comes to reclaiming precise, confident steering on a classic truck, muscle car, or off-road rig, few names carry more weight than Borgeson Universal. The company has been engineering steering solutions since 1914, and its lineup of steering gear boxes represents the sharpest edge of that century-plus of expertise. Rather than simply remanufacturing old designs, Borgeson develops all-new, modern integral gearboxes engineered to replace worn or underpowered original equipment with genuinely improved steering dynamics.

The Street & Performance Series

The flagship of Borgeson's gear box catalog is the Street & Performance Series, a line of quick-ratio power steering boxes purpose-built to replace aging Saginaw and Delphi 800-series gearboxes in popular GM applications. The Street & Performance box delivers a quick 12.7:1 ratio with a firm, modern steering feel — a significant improvement over the vague, slow response of original units. Critically, these boxes are engineered as direct bolt-in replacements: they mount to the stock frame location and accept factory pitman arms, steering shafts, and power steering hoses, minimizing the complexity of installation.

Coverage spans a wide range of popular platforms. GM muscle car enthusiasts will find Street & Performance boxes engineered to replace the Saginaw/Delphi 800 series in most 1964-and-up GM A-Body, F-Body, and B-Body vehicles. Truck builders are equally well served, with dedicated fitments for 1968–1986 Chevy/GMC 2WD trucks as well as the widely popular 1988–1998 OBS Chevrolet and GMC trucks.

Mopar, Ford, and Dodge Applications

Borgeson's steering gear box reach extends well beyond the GM world. For classic Mopar owners, Borgeson developed a modern quick-ratio power steering box specifically for 1962–1982 Mopar cars. This box features a 14:1 ratio with just 3.5 turns lock-to-lock, bolts directly to the stock K-frame, accepts the stock pitman arm, and even sheds approximately 10 pounds compared to the factory unit — a welcome bonus on any build. Ford and early Bronco fans are covered too, with integral power steering conversion gearboxes that represent the latest generation of integral power steering technology and a responsive 14:1 ratio, all adapted to bolt into factory mounting locations.

For heavy-duty Dodge Ram 2500/3500 owners, the Borgeson “Dodge Box” is a well-known solution featuring a large-diameter piston for maximum available power assist and a modern variable valve designed to provide stable highway feel while still making low-speed maneuvering effortless.

Built and Backed in the USA

A key differentiator across the entire Borgeson steering gear box lineup is the 3-year warranty and the fact that all units are assembled and tested in the USA. Borgeson also owns the original equipment, tooling, and patent rights for Saginaw manual steering gear boxes — a unique distinction that speaks to the depth of their engineering heritage. Whether you're upgrading a street rod, restoring a classic muscle car, or improving steering response on a daily-driven truck, Borgeson steering gear boxes deliver modern feel with proven fitment precision.
