2-1/2" Dia. Coil-Over Springs
PAC provides top quality coil-over springs to the motorsports industry. An in-house dynamics laboratory is used to test and set baseline standards
for load loss, spring weight, and fatigue life. Each spring is labeled with the rate and includes a corrosion-resistant powdercoated finish.
