King Shocks maintains one of the largest spring inventories in the off-road industry with over 10,000 springs in stock. Unlike repackaged automotive springs, these coils are purpose-built for off-road applications where consistent performance and reliability are critical. The spring rate of 400 lbs/in means it requires 400 pounds of force to compress the coil one inch, providing firm support for heavier vehicles or aggressive driving conditions.
