What It Helps Address

• Front-end sag from worn or fatigued coil springs
• Uneven ride height on Ford Thunderbird or Mercury Cougar front suspension
• Reduced suspension support after spring metal fatigue
• Noise or harshness caused by weakened front springs
• Restoration work requiring OE-style front spring replacement

Installation Notes and Tips

Install on the front suspension only. Verify spring orientation and inspect related suspension components before assembly. Because coil springs store significant energy, use proper spring compression tools and follow service manual procedures during removal and installation. Confirm vehicle application by year, make, model, and front position before ordering.

Lesjofors manufactures these springs using high-strength steel, heat treatment, shot peening, zinc phosphate coating, epoxy powder coat paint, pre-setting, and testing to support OE-quality replacement performance.
