SWIFT SPRINGS #120-250-350 B Barrel Spring 12in x 2.5in x 350#
BARREL SPRING 12IN X 2.5IN X 350#
All of SwiftStandard 10and longerCoilover 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)
One approach would be to increase the number of coils on the springs. With more coils on the spring, you will experience less bowing motion. This is the easy and cheaper method to solve the issue. But the downside of this method is a decrease in suspension stroke, increase in un-sprung mass, and will effect the overall movement of other suspension components.
Unlike others, Swift designed barrel springs with one common rule, which is all the barrel springs design have a maximum of 4OD. 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.
Generally speaking, the barrel designed springs tend to be heavier in weight than straight shape springs, but Swift coil springs will never have this problem because of our world leading coiling technology .
