Stiletto Ultra Spindles are CNC machined and precision honed from a heat-treated American produced Chromoly (4130) forging. The forging process aligns the steel grain structure within the shape, resulting in maximum strength - tougher than a billet produced counterpart. These spindles are the preferred choice for Dragsters, Funny cars and Altereds. To further ensure a superior finished product, each spindle is individually hardness tested, and 100% non-destructive Magnaflux inspected; even the spindle nut is forged and precision machined. The 8620 king pins are rifle drilled to remove unnecessary material, hardened for maximum wear resistance and precision center-less ground. The structured, sintered alloy, PTFE impregnated bushings and thrust washers, provide smooth steering and superior durability. These exceptional low friction materials will perform dry, lube is only needed during initial assembly to curtail the possibility of corrosion. High tensile ARP 12 point fasteners are standard, providing ultimate strength in securing the Chromoly steering arms and domed aluminum cap. Optional tow caps are also available separately. Engineered and race track proven for many years, Stiletto Steering components are the best value in racing and precision crafted in the USA. The spindle diameter is dimensionally the same as the Early English Ford Anglia. Complete Set Includes:(2) Spindles(2) 5 in. x 1/4 in.
