Strutmasters' air to non-air suspension conversion kit saves LS owners time, frustration, and money when the air suspension system goes bad. This kit, manufactured in America, comes complete with two front strut assemblies with cold-wound steel Eibach coil springs. Detailed instructions, online installation videos, and tech support from an ASE-certified expert all help you get the kit installed in as little as one hour per wheel. The quality parts are backed by Strutmasters' Lifetime Limited Warranty. Lastly, the cost of the kit is a fraction of dealership direct replacement and aftermarket part replacement.
