Best price anywhere online

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!

Tried to get questions answered to no availe !

Great Prices ! ! ! Quick and easy checkout. Quick delivery :)

Best Price on this product that I've found. Thank you Unfortunately I'm going to have to return the item since it won't fit my application.

Thanx, Process works good!

Great prices, wish you had more in stock though... free shipping over 300.00 would be nice too...
