Good prices. Shipping is a bit slow. I would order for autoplicity again.

I have a feeling these shocks are not available.

One of the simplest orders I have placed for autoparts. Well done

Great

Well, I'll start with saying this...I wanted a specific product from COBB tuning that they sell. It was priced lower than any other company so I bought it. This happened on the 22nd, I ended up calling them almost a week later to request tracking info. They were very friendly when they notified me it wouldn't be able to ship out till the 3rd of feb. For a 2 lb item I thought this was pretty slow. They apologized for COBB holding the order up. Its now the 7th, should get my item today!! Overall its a good company with friendly employees, Shipping time is lacking but a trade off for the lowest price. I would refer a friend for price and also mention shipping time expectations. I do believe there's something to be said for quality customer service and low prices...It's becoming harder and harder to find companies that posses such qualities. Honestly, if they had a faster shipping method I would give them a perfect rating.<br>
