King Shocks 3.75 ID Coil Springs 10.5 x 400lb

These King Shocks coil springs measure 10.5 inches in length and have a spring rate of 400 pounds per inch. They are designed with a 3.75-inch inner diameter, making them compatible with many popular coilover shock bodies. King Shocks uses high-strength steel for their springs, ensuring they can handle the rigors of off-road use and maintain their intended spring rate over time. This attention to material and design helps provide a consistent and predictable ride quality for your vehicle's suspension.

When selecting coil springs, the length and spring rate are critical for tuning your suspension's performance. A longer spring might offer more travel or allow for different preload adjustments, while the spring rate directly impacts how much force it takes to compress the spring. This 400 lb/in rate is a common choice for balancing ride comfort with control for many truck and SUV applications. King Shocks is known for producing well-built suspension components, and these springs are no exception, offering a solid option for those looking to fine-tune their vehicle's handling.
