12.7:1 Ratio Power Steering Box

The 12.7:1 Ratio Power Steering Box from Detroit Speed Engineering is designed for high-performance and modified vehicles, providing precise and responsive steering control. This steering box is ideal for drivers and mechanics who prioritize superior steering geometry and reduced slop during aggressive driving, track work, or precision automotive builds.

Engineered with tight tolerances and precision internals, this steering box eliminates the notchy, disconnected feel often found in aged factory units. The robust construction and sealed design ensure consistent performance under the demands of modified suspension geometry, wider track widths, and responsive driving techniques. The 12.7:1 ratio provides a balance between quick response and manageable steering effort, making it suitable for vehicles with lowered, widened, or larger-tired setups.

This steering box fits classic and modern platforms that utilize recirculating-ball steering systems, making it a valuable upgrade for classic restorations, performance builds, and track use. Whether you're restoring a classic muscle car or enhancing a daily driver, this performance-grade steering box offers direct feedback and consistent response across the full steering range.
