I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

Great pricing and quick shipping. I'll be using them again for sure.

After having trouble completing the payment process through Amazon, I was able to complete my payment information directly on the Autoplicty website and submit the order quickly. The process was easy and fast. They had the best overall price (item plus shipping) I could find on the net. The item was shipped promptly and arrived in great condition. A quality merchant all the way around.

Had a problem but they fixed it. Fast shipping.
