Good parts and price with shaky shipping
April 30, 2020
I like the quality, price and warranty of the parts I received. However, the shipping took a long time and my parts were delivered to a Home Depot approximately 20 miles from my address. I had to figure this out on my own and make multiple phone calls and a trip to Home Depot to retrieve my parts. Thanks, 1A Auto and/or UPS.

Water pump / fan clutch
March 24, 2021
We loved the fast and convenient service . It fit our Blazer just like they guarantee . The instructional videos are awesome ! The video walked you right through what you needed to do . The best part of the whole thing was that we saved over $100. I called a couple of our local auto parts places and they both came up with $260 for both parts, 1aauto.com was only $129 for both .
