    This product is priced individually and must be purchased in pairs of 2.

    Less unsprung mass, more stroke, increased handling. The only thing you will be loosing is track time.

    All of Swift Springs are made with our exclusive material called H5S.TW. Without this specially designed material, our light weight spring design would not exist. All of Swift 10" or longer springs are barrel design; the design is to solve all spring bowing problems. With bowing springs, you can expect spring rate inconsistency, and rubbing against shock body that would lead to damages on the shock adjusting perch thread. (Except Swift Drag racing springs).

    Unlike others, Swift designed barrel springs with one common rule, which is all the barrel springs design have a maximum of 4” diameter.(Usually located on the center coil of the spring) Because most other manufacture do not design their barrel springs with this rule. Most of their barrel springs outside diameter will differ from one rate to another. This creates a hard time for racers to test and see which rates will fit and which rate does not. A heavier rate spring tends to interfere with the suspension A-arm or other suspension components.
