GM Polished Aluminum 9 1/2 x 2 1/2 brake drums 5 on 4 3/4" bolt pattern.
Check out aluminum drums on ebay, almost twice as much. READ ALL - I bought these used drums on Ebay ten years ago for my 68 Chevelle from a man that had over a thousand sales and 100% positive feedback.
They were painted silver when I got them and I sprayed them satin black and hand polished the fins. The black paint have a few minor chips but the polished fins sparkek in the light and look great ( better than photos ). They stayed on my shelf for months before I tried to put them on my car ( before installing springs and shoes ) only to discover the lug bolt holes were 1/2" when my car had 7/16" lug studs. May work fine with tapered lug nuts but not on my American T2'S.
Features include:
* Aluminum composition resists corrosion and prevents rust from forming
* Aluminum construction provides a lightweight alternative to heavy cast iron, producing a lower-inertia drum that stops quicker
* Friction build-up is drastically reduced on the drum liner surface, decreasing brake fade and potential damage to the shoes
* Product metallurgy significantly increases heat dissipation while using the existing OE cooling fin design.
