King Coil Spring Length Rate

King Shocks coil springs are universal off-road and racing coilover springs. They are available in a range of free lengths and spring rates, so you can match them to your suspension setup. Each one is a linear-rate coilover spring, and the rate is the amount of force in pounds needed to compress it one inch.

Key Features:

• Made in the USA to King's own specifications
• High-tensile chrome silicon wire for strength and consistent spring rates
• Closed and ground ends that sit flat and deflect true
• Wound for off-road use, not repackaged car springs. Rates, wire diameters and coil lengths were developed through extensive real-world testing on all types of terrain.
• Race-proven design from King's competition use, from Baja to Dakar
• Protective powder-coat finish to resist corrosion
• Wide selection of lengths, rates and inside diameters, so you can choose the right spring for your coilover and vehicle weight

Choosing a Spring: King part numbers show the spring's inside diameter, length and rate. In the example SPR375-22-250, 375 is a 3.75 in. inside diameter spring, 22 is the length in inches and 250 is the rate in lbs/in. Select the inside diameter that matches your shock body size. Pick the rate based on vehicle weight and added equipment such as bumpers and winches.

King backs its springs with a lifetime limited warranty to the original purchaser against sagging and breakage.
