Intended only for drag racing, our fabricated spindles are CNC-machined out of 4130 material and weigh less than six pounds. This is our direct replacement for the common (and outdated!) Pinto/Mustang II spindles, these new spindles have a black-powder-coat finish, 1/2"-20 thread in the steering arm, and feature relief-milled steering-arm and balljoint bosses to save weight. Use with our 8335 light-duty brake kit. BARE METAL FINISH
