PST’s new Drop Spindles are designed to lower your vehicle, improve handling and maintain the original ride quality of today’s cars. Our Drop Spindles are high quality reproductions of the original GM units, but with a 2” drop height. Also, our Spindles allow you to convert to front disc brakes using locally available parts. These Spindles maintain factory suspension geometry, eliminating excessive ball joint, shock, and tire wear. To assure safety, each spindle is machined from high strength ductile iron; spuds are made from 4140 heat-treated chromoly steel. Our high quality spindles maintain original ride. The Steering Arms are moved back for maximum rim clearance.
