doesn't give axle side on description, axles look good have yet to install

great price hope it fits factory replacement

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

Easy to find the lighting needs for my 1999 Dodge Ram Van 3500. Shipping was okay for this order at six bucks.

Autoplicity had the item I wanted at a cheaper price than anybody online or in stores. They didn't have the item in stock, but they were very informative as to the status of my item. They have shown unheard of customer service via email since the inception of my order. I will definitely do business with them again.

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>
