A complete coil over system is one solution to improve your vehicle’s performance. The system combines springs, shocks and bump stop into one assembly. The coil-over set-up is similar to a race set-up in that it allows tuning of the vehicle through ride height adjustment. Coil overs often use an adjustable spring perch that allows for different vehicle ride heights without changing the springs.
Springs encompass the shock and bump stop, working to minimize bounce that occurs during driving. Shocks help control suspension movement while bump stops keep your vehicle suspension parts from coming in contact with the vehicle’s frame.
