A bar of resilient metal wound into a spiral that may be compressed or extended without permanent deformation Coil springs have many automotive applications but are particularly important as suspension springs
A spiral-wound steel wire coil, of various wire diameter thicknesses and coil stack heights, used to suspend a vehicle Can be used in cars and trucks, both front and rear, depending on the application
The coil spring supports the vehicle's weight and keeps it suspended Coil springs are made of a coil of tempered metal that takes the compression loads as the vehicle goes down the highway
A thick steel wire that has been coiled and heat-treated to form a very strong spring Commonly used in car and light truck suspension systems, coil springs are space-efficient and can vary in stiffness, even within the same spring (i e , stiff at the top and not stiff at the bottom) The coil springs on a given vehicle largely define how that car or truck's ride and handling will feel
