Hi all, can anyone point me towards the right direction for the OEM part number on a cobalt ss 2.0 super charged 2007 front rotor? Im on rock auto now to order however there are too many choices in the ac delco lineup which confuses me. The part number I think is correct is acdelco:177-1009 but im unsure.Just above this number is 1771004?? so im confused.My car has ABS ,but also both part numbers say abs wtf? Any help would be much appreciated,I don't want to buy any of the other makes on rock auto I had my experience with power stop rotors..................... 30k and soooooo much steering shake its retarded.Thanks again for any help

 

18A1659A ac delco
oem 19241831

run about 30 dollars or so plus shipping or go to Crate Engine Depot. Good luck

 

your sig doesnt say where you are in Canada, we generally carry rotors in stock but I only have resurfaced LSJ rotors at this time. AC Delco make good replacements.. but service your calipers, if the slides or the pistons are hanging up, bad things like pulsation can happen.
