This incredible new kit is great! This design allows for rear axle to frame clearance on trucks that have been lowered in the rear this well designed kit can be bolted in to place in just a few hours. It can also be welded in place for more strength on vehicles towing trailers. Welding is not required for most vehicles as no weight is supported behind the rear axle. All suspension connections are made ahead of the axle on coil spring trucks. Brothers has installed this kit in our 1971 suburban project vehicle and we love it. With rear end lowered over 6 it still rides perfect. (Suburbans, 2wd blazers and panels may require slight modification to c-notch kit, call for details). You will not have to worry about metal-to-metal contact or riding on the snubbers again! Kit comes complete with urethane snubbers.
