Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

Best price I could find after hours of searching, I recommend 100%!!!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.

Lightning fast shipping!!! I expected it to be here in 2-3 days, not the next.

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
