Ordered a set of Bilsteins on Sat. afternoon, and woke up today (monday) with a shiiping order #...Place is awesome, will order/refer..thank you

Shipping was fairly quick. I'm satisfied so far. I hope the product is as describe.

Timing gearset arrived in under 48 hrs! Gears look well made. Can't wait to get them on my car. Thanks for the great service!

Thanks - Great Product. Fast Shipping. Plus they answer the phones!

Easy ordering and the best price I could find on the internet. However, I wouldn't have found this part by looking on the Autoplicity web site! The only way it showed up was doing a google search for that specific part.

Purchased a K&N air filter for a Kawasaki motorcycle on a Saturday and received it on Wednesday...pretty quick shipping!
