The Big Wig 2800 lb. air springs are 2 larger in diameter and up to 3 taller than the standard 2500 lb. air springs on the market. The large air springs in the Big Wig kits have more air volume to provide ride quality and performance that can't be beat with or without a heavy load. Hellwig's Big Wig Air Kits require up to 40% less air pressure than a 2500 lb. air springs to level the same load. Lower air pressure provides a softer spring rate for ride quality you can feel and less wear and tear on the chassis. The larger air springs also provide better off-highway performance as the air springs in this kit will extend up to 14 for articulation that can't be matched. These kits features Hellwig's bulletproof brackets and hardware, air line and fill valves which are covered by a limited lifetime warranty. All Hellwig Air Spring Kits include easy to follow step by step instructions. For the ultimate tow package, add a set of Hellwig's Big Wig Sway Bars to give you more control and comfort in towing and hauling situations.A family owned business for over 65 years, Hellwig Products specializes in 100% American Made, precision engineered products.
