Ridetech coil springs on this page are sold by size and spring rate, which makes them a building block for custom and classic suspension work. Titles list free length, spring rate in pounds per inch and inside diameter, and the range runs from short, stiff springs to longer, softer ones.
A spring rate is how much load it takes to compress the spring by one inch. A higher number is a stiffer spring. Free length is the height before it is loaded, and it must fit the space in your shock or coil-over. The inside diameter must match the spring seat or the coil-over body you are using. Match all three, and check them against the shock manufacturer's recommendation.
The vehicle list is mostly older General Motors models: the Chevrolet El Camino, Chevrolet Bel Air, Chevrolet Camaro, Chevrolet Blazer, Chevrolet C10, GMC Jimmy, Pontiac Firebird and Pontiac Grand Prix. There are also listings for front lower StrongArms with stock style coil springs for the Chevrolet C10 truck.
Because most springs are universal, the vehicle selector helps only for the vehicle-specific kits. Each product page lists the years, makes and models it fits where that applies. For other brands, see the full Coil Springs range. Priced in Canadian dollars and ships across Canada.
