These air helper springs mount inside the existing coil springs and let you tailor the spring rate by adding or releasing air, helping the suspension better support extra weight without sacrificing ride quality.\u003c\/p\u003e\u003cp\u003eBy adjusting air pressure (typically around 5-45 PSI), you can reduce sag when carrying cargo or towing, improve vehicle stability, enhance steering and braking performance, and decrease bottoming out on rough roads. The elastic polyurethane air springs are built for durability across a wide range of temperatures and a long service life. Installation is straightforward for many compatible vehicles, and all necessary springs, hardware, air lines, and manual valves are included for a complete setup.\u003c\/p\u003e","brand":"Firestone","offers":[{"title":"Default Title","offer_id":53465158353215,"sku":"FIR4100","price":129.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/4f62196e863247c4e23e046ea73f7e40.jpg?v=1780178397","url":"https:\/\/wcaperformance.com\/products\/firestone-coil-rite-air-helper-spring-kit-front-63-99-p30-w237604100","provider":"WCA Performance","version":"1.0","type":"link"}
