I was very skeptical of ordering from Autoplicity, as I've never heard of them. They had everything I needed in stock and shipped very quickly, and for a much better price than my normal suppliers at Jegs and Summit Racing. I would recommend them to everyone...............Jeff

Need more specific details on item.

Very friendly customer service! They also shipped my radiator out very quickly. I will definetly be ordering from autoplicity again!

Amazing !! FAST SHIPPING and GREAT PRICES !! I couldn't ask for better !! I will definitely shop with Autoplicity again !!

Ordered Thursday, shipped Monday... guess all in all we can't be disappointed. At least they had them in stock.

I build engines for Classic muscle cars and hot rods. Presently assembling chev. SB 383 cu/in. Went shopping for a Name Brand rotating assembly that was complete and ready to install.Shopped several other sites before finding "Autoplicity" Prices were GREAT (best I could find Anywhere), Shipping Very prompt, Shpg. charges Very reeasonable,I will Defenitely use them again!!!

Good prices. Good communication.

Not sure if they overlooked my order but I didn't get my shipping info (3 days after ordered) until I emailed asking for status update. I received a response the following day and all my items ordered came 2 days later...much faster than I had anticipated considering the "delay" or lack thereof (5 days total). Long story short...items are as described, best prices (from what I can researched online for same items/brand) and resonable shipping prices. the selection and brand(s) offered were somewhat limited for my specific needs, otherwise I would've ordered more.
