The CS8023 spring for 1964,1965,and 1966 Mustangs is designed to lower the front suspension between approximately 1 1/4 inches. The spring is best suited to be used with Global West's UCA20 upper control arms. You can use this spring with other upper control arms however the drop may be slightly different. This spring has a rate of 540 pounds and is perfect for performance street applications without generating a harsh ride. If ride height needs to be adjusted for a specific look, a mere ¼ of a coil will lower the ride height 1 full inch. The springs are powder coated black and are preset so the ride height you see will not change.
Global West springs are made in the USA.
