A-Premium Power Steering Pressure Hose Assembly — Pump-to-Rack/Gear Direct-Fit for 2007–2014 GM Trucks, High-Pressure

A-Premium Power Steering Pressure Hose Line Assembly connects the pump to the rack/gear to restore reliable high-pressure steering fluid flow in compatible GM trucks and SUVs.

This pressure line is a direct-fit replacement engineered for select Chevrolet, GMC and Cadillac models from 2007–2014. Built to meet or exceed original equipment specifications, it combines multi-layer rubber and galvanized steel tubing with a double-locking fitting design to handle high working pressures and resist heat, corrosion and impact. The assembly is sized and routed for pump-to-rack/gear service and includes reference OEM numbers for quick verification.

Which vehicles will this hose assembly fit?

The line fits a range of GM full-size trucks and SUVs. Confirm compatibility using your year, make, model and engine size before purchase to ensure correct routing and fittings.

• Chevrolet Avalanche 2007–2013; Silverado 1500 and 2500 models and Suburban/Tahoe variations listed in fitment details
• GMC Sierra 1500 and Yukon/Yukon XL 2007–2014 coverage (exceptions noted for specific trims)
• Cadillac Escalade, Escalade EXT and Escalade ESV 2007–2014 for 6.2L engines

How durable and pressure-rated is this power steering line?

Designed for demanding hydraulic service, the assembly provides a high working pressure limit and substantial burst strength. Its construction and tensile rating deliver reliable operation under heavy steering loads and temperature extremes.

• Max working pressure: 1,500 psi for continuous hydraulic use
• Burst pressure ratings: 8,700–10,000 psi for safety margin under overload
• Tensile strength: 1,600 lb to resist stretching and deformation

What features reduce leaks and make installation straightforward?

The hose employs multi-layer materials and a double-locking fitting to minimize leaks and preserve system pressure. It follows original equipment geometry to help ensure a smooth swap with minimal modification.

• Multi-layer rubber with galvanized steel tubing for rigidity and fluid sealing
• Double-locking mechanism on fittings to prevent hydraulic fluid seepage
• Corrosion and impact resistance for longer service life and reduced maintenance

Are there OEM reference numbers or specifications to verify fit?

Yes—reference numbers and detailed specifications help you cross-check part compatibility. Use these identifiers when comparing to factory parts or ordering replacements.

• Reference numbers: 3402221, 15812564, 25858603 for cross-reference
• Position: pump to rack/gear — confirm routing against your vehicle's system
• Meets original specification dimensions and connection types for direct-fit installs

Who is this for: Technicians, DIY mechanics and fleet operators who maintain full-size GM trucks and SUVs and need a robust, OEM-compatible pump-to-rack power steering pressure hose. It’s ideal when the existing hose shows signs of leakage, hardening, external damage, or when replacing worn fittings to restore proper steering performance and avoid fluid loss.
