The only negative about the process was the shipping cost vs delivery time. The cost was steep for the amount of time it took to arrive.

Installation was a breeze. The roof rack looks great and paint color black matches our Blazer perfectly.

The website is easy to use. Found the part i needed. It came promptly. It was a good experience and I would recommend Gm Parts Giant.

Took over a week to ship
Took over a week to ship. Ordered Monday. I emailed asking for shipping info and I was told that it was shipping the next day. This was Thursday. A shipping label was created Saturday. It didn’t actually ship until Monday. One week after I ordered. Don’t order from here if you need it in a reasonable amount of time

Wouldn’t take unopened parts back after a 2 day span. Waited over a month for a RMA exception, only to find out it was denied. Avoid this circus altogether if you can..

Thank you for your feedback. Unfortunately, per our return policy we cannot proceed with your RMA due to open package. Please refer to our return policy below. Again we apologize for the inconvenience. Your feedback is essential for improving our services.”
The boxes were completely unopened, neither the shipping box that it came in, or the manufacturer’s packaging, which was both stated in the RMA request. The parts were completely unopened/unused. As if your response to this review isn’t enough evidence of your lack of understanding, because it clearly states in the review “unopened”.
This again only adds to the insanity that you call a customer service program.
Absolutely do not use this company ever.

This is my first time ordering from you. The bundle of parts I ordered were almost 200 dollars cheaper than my local Honda dealership wanted for them. The shipping was decent. And the packaging was the best I have seen! Everyone else just throws a part in a box and lets it rattle around.

Customer service is a joke
Customer service is a joke. Passed me around 3-4 times. Delaying the part eta time and I can’t cancel the order, never again will I use their company for any parts.

Unprompted review
I previously ordered steering rack…
I previously ordered steering rack 84297138 from them for my car, but order VG96648504 was canceled.
I submitted a new request for this part and received a response today that it is available for order.
Can I now purchase this steering rack?
Your response:
Part Number. Status
84297138 Available*. Click to order.
Today I ordered steering rack 84297138 again, and order VG06651129 was canceled again.
First, you say I can order it, and then you cancel the order. Is this a scam or something?

Thank you for your feedback. In some cases, the manufacturer may place an item on backorder, provide no estimated availability date, or discontinue the part entirely. When this occurs, we are required to cancel the order to avoid further delay.
We understand how frustrating this can be and appreciate your understanding. Your feedback is essential for improving our services.
