Wilwood's ProSpindle is specifically designed for use in fabricated A-arm suspensions on kit cars, street rods, drag cars and other custom or race applications configured around Pinto/Compatible with Mustang ll suspension geometry. A redesigned one-piece forged steel body uses common Pinto and Compatible with Mustang ll tie rod ends, ball joints, wheel bearings and seals. It is lightweight yet nearly three times stronger than OE or aftermarket two-piece cast iron and steel replacement spindles. Bolt-on steering arms are strong and can be reversed to accommodate rear steer configurations. They also allow the same spindle to be used on either side of a vehicle. Bolt-on caliper brackets attach to substantially reinforced mounting bosses on the spindle body for secure, deflection-free mounting of four or six piston calipers. Complete Wilwood ProSpindle applicable brake kits and components including forged billet hubs, bearings, seals, locknuts, calipers, brake pads, caliper brackets, and hats or rotor plates to attach optional rotor styles from 11" to 14" are all available to configure custom brake packages and complete the installation.
