King Shocks 3.75 ID Coil Springs 16 x 600lb

This is a King Shocks 3.75 inch inner diameter coilover spring, measuring 16 inches in length with a 600 pound per inch spring rate. It's designed to work with coilovers that accept this specific spring size and rate, often found in performance or custom suspension setups.

King Shocks is known for its well-built suspension components, and these springs are no exception. The 600 lb/in rate offers a firmer ride than stock, which can improve handling and reduce body roll during spirited driving or off-road use. The 16-inch length is a common size for many performance shock bodies, but it's always best to confirm your shock's compatibility with this length and diameter before purchasing.

When choosing a spring rate, consider your vehicle's weight and how you intend to use it. A 600 lb/in spring is a solid option for many trucks and SUVs looking for improved suspension performance without being overly stiff for daily driving.
