Sunsong Power Steering Pressure Line Hose Assembly 3401061 — Complete OEM-Fit Kit with Brackets & Zinc-Plated Steel

The Sunsong 3401061 is a complete power steering pressure line hose assembly engineered to replace OEM lines on select Cadillac, Chevrolet, and GMC models for dependable steering fluid delivery.

Built by a global fluid-transfer specialist, this Sunsong assembly is manufactured to match original equipment fit, form, and function. The kit includes all wearable hardware—brackets, grommets, molded guards, clips, and sleeves—so you restore the entire pressure line system without scavenging parts from the old hose. Components are produced from high-grade steel with a zinc electroplate finish to resist corrosion and chemicals common in under-hood environments.

Which vehicles does this Sunsong hose fit?

This pressure line assembly is designed to fit a defined range of American full-size SUVs and trucks. Compatibility covers model years across Cadillac Escalade, Chevrolet Avalanche, Silverado, Suburban, Tahoe, and multiple GMC Sierra and Yukon variants. Always verify part fitment against your vehicle VIN or factory part number before ordering.

• Cadillac Escalade: 2002
• Chevrolet Avalanche 1500: 2002
• Chevrolet Silverado 1500: 1999–2005
• Chevrolet Suburban 1500, Tahoe, GMC Sierra/Yukon models: various 1999–2007 coverage

How does Sunsong ensure this hose matches OEM performance?

Sunsong manufactures hoses using engineering processes aimed at OEM equivalence. Tubing is formed from high-grade steel and treated with zinc electroplate to increase resistance to rust and chemical attack, while every assembly is pressure-tested to detect leaks and ensure reliability before shipping.

• High-grade steel tubing for structural durability
• Zinc electroplate coating for corrosion resistance
• Pre-shipment high-pressure leak test for quality assurance
• Includes all required brackets and protective hardware

What comes in the kit and why is that important?

The assembly ships with all wearable parts needed to replicate a factory-installed line, eliminating the need to transfer hardware from the old hose. Fresh grommets, molded guards, wire clips and protective sleeves protect the hose from abrasion, heat and vibration—common causes of premature failure.

• Brackets sized for factory mounting points
• Molded plastic guards and protective sleeves to prevent chafing
• Wire clips and grommets to secure routing and reduce vibration
• Complete assembly ready for bolt-on installation

How simple is installation and what should I check?

Installation is straightforward for technicians and experienced DIYers who are comfortable working under the hood. Because the assembly is a direct-fit replacement, labor focuses on removing the old line, transferring any vehicle-specific fittings if necessary, and torquing new connections to spec. Inspect steering fluid level and bleed the system per manufacturer guidelines after installation.

• Direct-fit design minimizes modification or fabrication
• Follow vehicle torque specs for pressure fittings
• Flush or top-up power steering fluid and bleed air from system
• Confirm no leaks under pressure before driving

Who is this for: The Sunsong 3401061 assembly is intended for owners and technicians maintaining late‑1990s to mid‑2000s GM full‑size trucks and SUVs who want an OE-style replacement without sourcing multiple separate parts. It suits fleet maintenance shops, independent repair garages, and do-it-yourselfers who prioritize corrosion resistance, complete hardware inclusion, and pre-tested reliability for power steering pressure lines.
