ordered a hub rebulild kit and found Autoplicity to have the lowest price. Easy ordering and good communication re: when product shipped. Turnaround was satisfactory.

First time I've tried these guys. Had trouble getting this product from my normal source (backordered) but Autoplicity shipped quickly and had a better price too! You know I will be back! Thanks!

Good price, great presentation and easy navigation.
