Love them!!! They send E-Mail conformation when order is placed and tracking number when shiped.

Definitely good prices and they shipped my order within a day. So far, they've had really good customer service.

Great prices... fast shipping......

Goo . Service

Autoplicity had the best price on the Wiseco pistons I needed anywhere. Took a little longer to arrive than I expected but apparently that was due to the pistons being shipped directly from the factory. Otherwise a very good experience overall.
