QA1 Coilover Spring and Shock Assembly GS401-10400A

Great product with a fair price!

Only issue I had was that order could not be completed on Amazon, stating "items cannot ship to your location." I simply went to your website and ordered items. So a little inconvenient, but no biggie.

It was better service than I expected A receive my things quickly and is better not thought Thanks very much

Thanks

Easy to order website.

My online shopping experience was great! My package arrived on time i actually received it at little earlier than expected. I will definitely be shopping with you guys in the future.

Good product at a great price,,was delivered before expected date.

Easy to use

Fast Shipping. Good packaging. Very good pricing. Will shop from again.

Great price and received item in a timely and in great condition. Will definitely shop here again!

After searching for the best prices for the product that I wanted, I ended up with Autoplicity. I quickly got a response that my product has just been shipped and I am very impressed that Autoplicity is giving me an incentive to write a review on them. This tells me that this company is very concerned with the satisfaction of their customers. I am currently waiting for the order to arrive, but so far, I am extremely confident and happy with Autoplicity!

great prices & shipping

Best price on the product I was looking for. Extremely fast shipping even with ground. Got my order out right away and it arrived very well packaged.

Customer Care took care of my return and refunded the shipping after there was some order confusion. Thank you for taking care of everything!

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984
