Replacement RC28950001 Power Steering Rack and Pinion Assembly RWD New

The Replacement RC28950001 is a brand-new hydraulic power steering rack and pinion assembly designed as a direct OEM replacement for rear-wheel-drive (RWD) Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. Built to restore factory-level steering feel and precision, this complete assembly is a bolt-on solution for worn, leaking, or damaged original equipment steering racks.

This steering rack and pinion translates rotational input from the steering wheel into the precise lateral motion needed to turn the front wheels. A failed or worn rack commonly presents as loose or unresponsive steering, fluid leaks, grinding noises while turning, or a steering wheel that wanders off-center — all issues this new unit is designed to resolve.

• Brand New Unit — not remanufactured or rebuilt; new components throughout
• Hydraulic Power Steering — designed for hydraulic power-assisted steering systems only
• RWD Applications Only — fits rear-wheel-drive models; not compatible with 4WD/AWD variants
• Front-Mounted Assembly — complete rack and pinion unit for front steering axle
• Rack Length: approximately 50.55 inches
• Mounting Hole Spacing: 14.88 inches center-to-center
• Pressure Port Thread Size: M18 x 1.5; Return Port: M16 x 1.5
• Lock-to-Lock Turns: 3.31
• Direct Bolt-On Fit — OE-matched mounting points for straightforward installation
