Sweet Steering Gear Box

Sweet Manufacturing Steering Gear Boxes: Precision Built for the Track

When it comes to racing-grade steering control, few names carry the authority of Sweet Manufacturing. Steering gear boxes are the critical link between a driver's inputs and the car's front wheels, and in motorsports — where fractions of a second separate the podium from the pack — the quality of that link is everything. Sweet Manufacturing has spent decades engineering steering gear boxes that deliver the precision, durability, and driver feel that serious racers demand.

The 700 Series: Sportsman and Lightweight Options

Sweet's flagship circle track offering, the 700 Series, is modeled after the trusted Delphi/Saginaw box design and is available in both standard Sportsman and Lightweight configurations. These steering gear boxes feature a 3-bolt housing and are offered in every combination of ratio and valve size, spanning 6:1 through 16:1 — giving builders the flexibility to dial in steering quickness for virtually any track or driving style.

The Sportsman line was developed with the budget-conscious racer in mind. Each unit features brand-new inner working parts installed in a remanufactured housing, with quicker ratios — 10:1, 8:1, and 6:1 — specifically engineered to eliminate the need for a separate steering quickener. Removing the quickener gives the driver a more direct, unfiltered feel at the wheel. The Sportsman boxes are also legal in all major modified sanctions, including IMCA, UMP, and USMTS/USRA, making them a go-to choice across grassroots racing series.

The 600 Series: Pro-Level NASCAR Engineering

For racers competing at a higher level, Sweet's 600 Series steering gear boxes are engineered to meet and exceed the expectations of top NASCAR Cup teams. Built around a 4-bolt housing configuration common to GM passenger cars, the 600 Series retrofits directly into any application previously using a 700 Series unit — yet it comes in at roughly 6 pounds lighter, a meaningful weight saving on a race car. Six ratio options ranging from 8:1 to 17.5:1 are available alongside eight different valve sizes, from an extra-light .185 up to a heavy .275, allowing teams to fine-tune hydraulic assist to precisely match tire compounds, track surface, and driver preference.

Quality Assurance: Dyno Testing and Center-Stamping

What distinguishes Sweet's steering gear boxes beyond their specifications is the rigor of their quality control process. Every box is tested on Sweet's own in-house steering box dyno before leaving the facility. Additionally, all boxes are run on a precision centering machine and stamped with the exact degree of the pitman shaft, ensuring the gear runs squarely on the center tooth and eliminating tight spots throughout the full range of motion — a critical factor in maintaining consistent steering feel lap after lap.

Sprint Car Steering Gears

Sweet has also been a recognized leader in sprint car steering for over 15 years. Their sprint car steering gear is the only box on the market offering multiple pitman shaft lengths and input heights, and it is available in both left-hand drive (dirt) and right-hand drive (asphalt) configurations. The chromoly housing, billet aluminum valve housing, and hardened-and-polished pitman shaft reflect the same commitment to lightweight durability found throughout the Sweet Manufacturing product line.

Whether you're campaigning a Sportsman modified on Friday nights or chasing championships on a full-time basis, Sweet's steering gear boxes offer a proven, American-made solution backed by decades of track-tested performance.
