The Mittler Bros. Big Ford 9″ / 8.8″ / GM 12-Bolt Car Inner Puck is a precision-machined alignment puck used in rear-end narrowing applications. It slips over the Mittler Bros. 1-1/2″ jig shaft and seats inside the Big Ford 9″ / 8.8″ / GM 12-bolt Car bearing bore to ensure accurate, square, and true reinstallation of the housing ends after narrowing.
With a 3.062″ OD, these pucks fit the Big Ford 9″, Ford 8.8″, and GM 12-bolt Car bearing bore — covering a wide range of popular rear-end housings commonly found in cars, trucks, and performance builds. Sold as a pair. Made in the USA.
