21.5 Tuned Power Rack & Pinion

The 21.5 Tuned Power Rack & Pinion from Detroit Speed Engineering is engineered for drivers seeking superior steering response and handling precision in performance-oriented vehicles. This tuned steering component replaces the factory unit with a ratio optimized for aggressive driving dynamics, reducing steering effort while maintaining the direct feedback critical for track work and spirited street driving. Built by one of the industry's most respected chassis specialists, this rack & pinion delivers the kind of steering improvement that transforms how a vehicle communicates with the driver.

Detroit Speed's tuning approach focuses on optimizing the internal gear ratio to reduce turns lock-to-lock while sharpening on-center response. The 21.5-ratio design achieves quicker directional inputs without sacrificing low-speed maneuverability, a critical balance for both road course and autocross applications. The assembly weighs 20 pounds and measures 45 inches in length, fitting standard mounting locations on compatible platforms. Quality construction and tight tolerances ensure consistent steering feel throughout the full range of motion, eliminating the play and vagueness common in aged or worn factory units.

This tuned power rack & pinion benefits drivers upgrading their vehicle's handling package, particularly those pairing it with modern suspension geometry, wider tires, and upgraded braking systems. Installation requires removal of the original steering assembly and is best performed by a technician familiar with steering column disconnection and tie-rod end alignment procedures. Compatibility varies by platform, so verify fitment with your specific vehicle make, model, and year before purchase. Once installed, the improved steering response and reduced effort make every drive more engaging while supporting confident control during performance driving.
