<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!

Best price around. Great Communication. Fast shipping. What else can I ask for?<br>I have already purchased again from them.

Quick shipping and they had the fuel jugs I needed for the best prices thanks!<br><br>UPDATE: they were so good I made another order with them within a week.

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

Great Pricing (lowest i can find anywhere) and Quick Shipping, Product has no damage from shipping! Thank you Autoplicity!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
