Each spindle is crafted from high strength ductile iron, CNC machined, with a powder coated finish. In 1983, Belltech developed one of the industry's first revolutionary products to help jump start the Sport Truck craze, the Drop Spindle.
I haven't install these spindles yet, hopefully no surprises. I am disappointed with the rough machining of the cast grease seal mating surface. the bearing surface is a press in, and looks good.
