Fit my 2004.5 2500HD duramax easily. Changed in about 20 minutes. Came with a replacement nut for the idler arm and the arm bracket. You will need to use the factory mounting bolts.

I did the whole front end of my 2002 Yukon SLE. Aside from Sway Arm links this was the easiest step. I suggest buying a new idler arm so you don't have to pull the original to press onto this part. Things are tight on these GM front ends. Simply pressing or beating the idler arm out of the steering linkage and then two bolts and you have the old one off. Either way, this is a review about this part and this part gets 5 starts

Perfect fit Every time. I always use acdelco on my Chevrolet

Great quality and on time delivery.

Great so far Will update if it fails prematurely

Replaced this also with the Idler arm so it should be there for another 14 years.

Excellent fit and quality. Nicely priced too
