Rated 4 out of 5 stars

I ordered the parts, they sent them, but they should have been packaged better, some damage. They sent the right parts, but GM has changed the internals, they are now junk. I won't use them.

You had the correct supercharger belt I needed and it was easy to order and was delivered on time. My only complaint was the shipping charge was a bit high for a single belt. Over all very pleased with the experience.

Updated : One of the parts arrived broken

Update. My review and issue was actually with another site (also stars with GMParts…) and not with GMPartsGiant. I looked again after they reached out to offer me a refund. Well played on their part! They seem like a good company that cares about their reputation.

Original:
One of the parts arrived broken, but since it was an $8 part, the cost to arrange a replacement was higher cost to me than just buying a new one from someone who would pack it with a little more care.
