Through our experiences from extensive testing in world class racing in Europe and Asia, we have great confidence that we can provide the same results in the US.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eBy knowing the main characteristics that American racer demands, we designed and engineered the standard measurement springs based on data that we had collected through racers that are at the top of their sport.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eMany enthusiasts will swap springs from brand to brand with the only noticeable difference being a stiffer or softer ride. But what if a spring could offer a noticeable increase in traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable feel? The engineers at Swift have taken that “what if” and turned it into reality.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAll Swift Springs are manufactured using (H5S.TW) which is far superior to silicone chrome steel and allows us to wind a much more responsive spring with less coils, resulting in reduced un-sprung weight and increased stroke.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eMost of Swift 10″ and longer springs (Excluding the Drag racing springs and Conventional springs) are barrel design; the design is to solve all spring Deflection (bowing) problems. With bowing springs, you can expect spring rate inconsistency, and rubbing against the shock body that would lead to damage on the shock adjusting perch thread. \u003cbr\u003e\u003cbr\u003eOne approach to assess spring deflection 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 spring stroke, increase in un-sprung mass, and will affect the overall movement of other suspension components.\u003c\/p\u003e\n\u003cp\u003eUnlike others, Swift designed barrel springs with ease and consistency of vehicle setup in mind, our barrel spring design has a maximum of 4″ outer diameter (except B5 and B4 series) (Usually located on the center coil of the spring). Because most other manufacturers 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 especially with tight clearances to test and see which rates will fit and which rate does not. A heavier rate spring can interfere with the suspension A-arm or other suspension components.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAfter years of research and development, Swift Springs would like to proudly present the BP Spring for circle track racing. Specifically designed to meet and surpass the unique needs of Circle Track Racers. Although specially made, these springs are constructed with the same SWIFT SPRINGS philosophy and that is to be responsive and increase overall traction.\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Swift","offers":[{"title":"125","offer_id":40027930394704,"sku":"160-350-125 BP","price":169.15,"currency_code":"USD","in_stock":true},{"title":"140","offer_id":40027945107536,"sku":"160-350-140 BP","price":169.15,"currency_code":"USD","in_stock":false},{"title":"150","offer_id":40027930427472,"sku":"160-350-150 BP","price":169.15,"currency_code":"USD","in_stock":true},{"title":"160","offer_id":40027945140304,"sku":"160-350-160 BP","price":169.15,"currency_code":"USD","in_stock":false},{"title":"175","offer_id":40027945173072,"sku":"160-350-175 BP","price":169.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0058\/0252\/4785\/products\/swift-springs-standard-coilover-spring-id-3-5-16-length-31132289957948_991x_4213d832-45cb-4a49-beee-ebde7ca205de.jpg?v=1674239004","url":"https:\/\/shop.redline360.com\/products\/swift-standard-coilover-spring-id-3-5-16-length-125-to-175-lbs-inch","provider":"Redline360","version":"1.0","type":"link"}
