Chevrolet 396-454 c.i. 8 Cylinder (1967-1996)

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

great experience, good price, item arrived within 4 days of purchase, would do business with again in future !

Autoplicity beat everyone's price even with the shipping on an item that no one else had in stock, but still listed.

Smooth easy process

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.

Easy order placement, fast shipment
