Steering racks are a core component of rack-and-pinion steering systems, converting rotational motion from the steering wheel into linear motion to steer the vehicle’s wheels. Typically located mounted to the vehicle chassis ahead of the front wheels, they utilize a pinion gear engaging a toothed rack to provide mechanical advantage. Internal valve assemblies within the rack housing can incorporate power steering assist via hydraulic or electric means. Rack construction commonly employs hardened steel for durability, and variations include differing rack lengths and gear ratios to modify steering response. Boot kits are essential for protecting piston rods from contamination and ensuring longevity.
