How does installation compare to the original parts?

The MuHize lines are manufactured to align with factory mounting points and hose connections so installation is straightforward. A typical replacement requires removing the worn lines and bolting the new hard lines in place—no reshaping or aftermarket adapters are usually necessary.

• Direct-fit design reduces installation time and effort.
• Preserves factory routing to prevent chafing and leaks.
• Supplied as a complete pair: one rack line and one pinion line.

What materials and protection features does this kit offer?

MuHize uses high-quality aluminum for the hard lines, chosen for a balance of strength and resistance to corrosion. The silver finish adds an extra layer of protection against road salts and moisture, helping extend service life compared with untreated metal lines.

• Aluminum construction for durability and weight savings.
• Corrosion-resistant silver finish for long-term protection.
• Manufactured to meet or exceed OEM standards for performance.

What comes in the package and what should I prepare for replacement?

The kit includes one steering rack hydraulic line and one pinion hydraulic line so you receive both transfer lines commonly replaced together. Before starting, gather basic hand tools, a drain pan for fluid, and replacement power-steering fluid to top up the system after installation and bleeding.

• Box contents: 1x rack hydraulic line, 1x pinion hydraulic line.
• Recommended tools: wrenches, line wrenches, drain pan, jack stands.
• Post-install: refill and bleed the steering system to remove air.
