This Lesjofors coil spring is engineered for rear suspension service on Ford Focus heavy duty applications across 2000-2010 model years. The 4227579 spring uses a manufacturing process that includes heat treatment, shot peening, zinc phosphate coating, and epoxy powder coating to support consistent performance and corrosion resistance. Lesjofors has a long spring-making history dating back to 1852, and its replacement springs are used in OE-style applications across Europe.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Restoring rear ride height on a Ford Focus with sagging springs
• Replacing a broken or cracked rear coil spring
• Correcting uneven rear stance on heavy duty suspension setups
• Addressing noise caused by weakened rear spring tension
• Returning rear suspension support after spring fatigue

Installation Notes

Verify the rear suspension type and model code before ordering, especially on 2000-2004 Ford Focus vehicles with Type DFW, DAW, or DBW notes. Because this spring is supplied without a seat, reuse or replace related suspension components as needed during service. Professional spring compression tools and proper rear suspension procedures are recommended for installation.

Lesjofors coil springs are manufactured to meet or exceed OE quality standards and are tested for consistency before release. The brand’s OE-focused spring production and long manufacturing history support dependable replacement use on Ford Focus rear suspension repairs.
