Installation Notes and Tips

Verify drum diameter, bolt circle, center hole size, and brake shoe width before installation. This brake drum is listed for front positions on most applications, with one rear fitment noted for the 1964-1966 GMC G1000 Series. Confirm whether your vehicle uses front drum brakes or the specified rear brake configuration before ordering. Inspect brake shoes, wheel cylinders, and hardware condition during service so the new drum can seat properly.
