How to Choose

  • Read the casting: diameter x width plus the bolt-hole count identifies any drum, whatever the brand.
  • Check the max-diameter limit cast into your old drum — past it, or with heat cracks, the drum is done.
  • Retail drum orders are pickup at our New Jersey warehouse; wholesale drums ship LTL freight, free on orders over $1,500 to NJ and NY.

Quick Answers

How do I know which brake drum fits my truck?

Match the size cast into your old drum — diameter by width, e.g. 16.5 x 7 — plus the bolt-hole count. Truck make doesn't matter; drums follow standard industry sizing.

Should brake drums be replaced with the shoes?

Measure first: every drum has a maximum diameter cast into the body. Past that limit, or with heat cracks and hard spots, replace the drum — worn drums shorten the life of new shoes.
