Great Communication and instant shipping. Well done!

very smooth

Great price on rancho shocks. Fast shipping great quality.

Competetive prices and fastest shipping I've experienced, will definately use again!!

Ordering was a snap, everyone else had it on back order, please let me know if it is on back order.

great store

Ordered Monday - didnt ship until Thursday.<br><br>Email sent tracking number, but didnt mention which source was used for transport.<br><br>Product as described.

Everything worked well for me with this order. The only funny thing is that Autoplicity claimed that the part I was ordering will not fit make and model of my car, despite the fact that I was ordering manufacturer part number specific to my vehicle.

Sales person was very helpful finding my old order and taking a new order for the same pump. Good prices. I will order again. thank you. John
