Holley Power Steering Line

Holley Power Steering Lines: Engineered for High-Performance Builds

When you're swapping an LS or LT engine into a classic muscle car, or pushing a purpose-built street machine to its limits, the power steering system is one of the most pressure-intensive plumbing challenges under the hood. Holley Performance has built a comprehensive lineup of power steering lines specifically to address those demands — combining decades of racing plumbing knowledge with purpose-designed hardware that integrates seamlessly with Holley's own accessory drive systems.

Triple-Braid Hose Construction for Extreme Pressure

Power steering systems are among the most demanding hydraulic environments in any vehicle. Due to extreme pressure spikes at the end of steering travel, power steering hose requirements are among the toughest in the industry. Holley meets this challenge through its Earl's Performance brand, offering a triple steel and fabric braid-reinforced high-pressure hose developed specifically to meet the demands of power steering systems, also suitable for hydraulic and air lines. Maximum burst pressure reaches 5,000 psi, with an operating pressure of 2,250 psi — figures that serious builders can rely on under sustained load. The hose is available in -6 AN sizing in both black and blue finishes, sold by the foot or in pre-cut lengths, giving fabricators the flexibility they need for custom routing.

Hardlines for Tight Clearance Situations

Holley also offers dedicated hardline solutions for builders working with Type II power steering pumps in tight engine bay configurations. The pressure hose connection on the Type II power steering pump sits close to the pulley, making hose attachment difficult due to limited clearance — so Holley's special hardline moves the connection behind and below the pump for improved clearance and a cleaner appearance. A mounting bracket is included to make the hardline stronger and less likely to crack from vibration or abuse. These hardlines are available in steel with zinc plating or nickel plating, and Holley offers application-specific variants for Mid-Mount, Low-Mount, LSA, and Gen III Hemi accessory drive configurations.

Matched Hose Ends and Adapters for a Complete System

A power steering line is only as reliable as its connections. Earl's redesigned the power steering hose ends with a more attractive one-piece design that eliminates the brazing of the bent tube to the other components. Hose ends are available in straight, 45-degree, 90-degree, and 120-degree configurations in both nickel-plated steel and stainless steel — making it straightforward to route lines in nearly any engine bay layout. Depending on your power steering pump, you may need inverted flare fittings or bump tube style fittings, and Holley's adapter catalog covers the most common Saginaw Type II configurations with nickel-plated steel AN-to-pump adapters.

For builders who need a remote-mounted reservoir, Holley's remote-mounted power steering reservoirs are ideal for applications that cannot fit a pump-mounted reservoir, featuring lightweight aluminum construction with an internal baffle and air separator to keep fluid from getting foamy or overflowing.
