King SPR3-18-700 3.0 Inch ID Coil Spring 18 Inch Length 700 lb Rate

The King SPR3-18-700 is a high-performance coil spring manufactured in the USA from premium high tensile chrome silicon wire, specifically engineered for demanding off-road applications. This 3.0 inch inside diameter spring features an 18 inch free length and a 700 lb spring rate, designed to fit 2.5 inch diameter shock bodies.

Key Features:

• Closed and ground ends sit flat and deflect true for consistent performance
• Spring rate etched in top for clear identification even after hard use
• Specifically wound for off-road applications with spring rates, wire diameters and coil lengths developed through extensive real world testing
• Powder coated for maximum corrosion resistance
• Purpose-built for off-road use, not repackaged car springs
• Sold individually

King offers a lifetime warranty to the original purchaser against sagging and breakage, providing peace of mind for your suspension investment. The 700 lb spring rate means it requires 700 pounds of force to compress the coil one inch, making this an ideal choice for heavier vehicles or more aggressive off-road applications requiring firmer suspension control.
