C-Tzu Power Steering Hose Kit for GM V8 Trucks SUVs — 2pc Pressure & Return Lines (Fits Silverado/Tahoe/Yukon, OEM 15812564/158125

Two complete high-pressure power steering lines by C-Tzu engineered to replace worn OEM hoses (15812564/15812565) and restore reliable steering function on compatible GM V8 trucks and SUVs.

These C-Tzu replacement lines include a pressure hose and a return hose sized and finished to fit a wide range of General Motors V8 vehicles from 2007–2014. Built with layered construction and oil- and heat-resistant synthetic rubber, the pair aims to deliver leak-resistant fluid transfer, high-pressure durability, and straightforward installation where original steering lines have failed or developed leaks.

Which vehicles and engines will these hoses fit?

The C-Tzu kit is designed for many GM models and V8 engine options across Chevrolet, GMC, and Cadillac. Confirm fitment by cross-referencing the listed OEM part numbers or matching hose lengths and connector types to your vehicle.

• Chevrolet Silverado 1500 (2007–2013) with 4.8L V8
• Chevrolet Tahoe/Avalanche/Suburban (2007–2009/2007–2013) with 5.3L, 6.0L, 6.2L options
• GMC Sierra/Yukon/Yukon XL (2007–2014) covering 4.8L, 5.3L, 6.0L, 6.2L V8s
• Cadillac Escalade (2007–2014) for 6.2L V8 models

How do these lines perform under pressure and heat?

C-Tzu hoses use a multi-layer design and heat- and oil-resistant synthetic rubber to maintain consistent hydraulic flow under demanding conditions. The materials and assembly resist swelling, hardening, and breakdown that can cause leaks or reduced steering response.

• Multi-layer structure for stable high-pressure fluid transfer
• Heat- and oil-resistant rubber for longer service life
• Factory-grade couplings and seals to minimize seepage

What exact parts and measurements are included in the kit?

This purchase contains two hoses: a pressure line and a return line, each cut to lengths matching common GM routing. The kit is made to match OEM connection types and includes fittings that accommodate both 3/8" and metric (16mm) interfaces for smoother installation.

• Power steering pressure line length: 50 cm (20.28 in)
• Power steering return line length: 43 cm (19.77 in)
• Compatible with OEM numbers 15812564, 15812565, 25858603 and others
• Dual 3/8" & 16mm compatibility for mixed fittings

Will this kit stop leaks and how reliable is the fit?

The hoses are constructed and sealed to reduce the risk of fluid loss, using high-quality connectors intended to replicate OEM reliability. Proper installation—tightening to correct torque and replacing any worn clamps or fittings—ensures the best leak-free result.

• High-quality seals and couplings designed to prevent oil leakage
• Manufactured to meet OEM standard replacement tolerances
• Recommended inspection of mating hardware during installation

Who is this for: This C-Tzu 2-piece steering hose kit is for owners and technicians maintaining mid- to late-2000s GM full-size trucks and SUVs who need a robust OEM-equivalent replacement. Choose this set if your vehicle exhibits power steering leaks, reduced steering assist, or if you're restoring hydraulic connections to factory-like performance while keeping compatibility with mixed imperial and metric fittings.
