700S LW Steering Box 6:1 -3/4-30 Input 185 Bar

The K.S.E. Racing 700S LW Steering Box 6:1 -3/4-30 Input 185 Bar is purpose-built for high-performance race vehicles and heavily modified street cars that demand responsive, reliable steering control under extreme conditions. This lightweight power steering box is engineered for drivers who refuse to compromise on precision, whether you're piloting a competition vehicle on the track or running a street machine with significant horsepower upgrades. The 700 Series platform has earned its reputation among serious automotive builders who understand that steering feel and response are non-negotiable components of vehicle dynamics.

This steering box features a 6-to-1 ratio, meaning that for every six turns of the steering wheel, the output shaft completes one full rotation—a configuration that balances quick responsiveness with driver control, ideal for race applications where steering precision matters. The 3/4-inch, 30-spline input design ensures robust connection to your steering column without play or deflection under load. Rated at 185 bar system pressure, this unit delivers consistent power assist while maintaining the lightweight construction that saves unsprung weight—critical on race cars where every pound affects acceleration, braking, and handling. The iron construction with natural finish provides durability and corrosion resistance, while the compact 13 x 9.5 x 14-inch footprint (25.7 lbs) makes installation feasible in tight engine bays without sacrificing performance or reliability.

This steering box is ideal for circle-track racers, drag racing enthusiasts, and street-rod builders who are upgrading to modern power-assisted steering systems on vintage platforms or replacing worn factory units on competition vehicles. The 3-bolt mounting pattern offers broad compatibility across multiple chassis and frame configurations, making it a versatile choice for custom applications. Installation requires proper power steering pump sizing and hose routing to match the 185 bar pressure rating; builders should verify pump output and system relief settings before startup to ensure optimal performance and component longevity.
