always happy with service

The Monroe shocks are the only way to renew the factory suspension to your Z55 optioned vehicle. As good or better than the triple price and now unavailable factory shocks.

No one informed us that there would be 2 separate packages of 5 each for total of 10 switches. This created some concerns regarding a possible shortage.

Thank you, perfect

Only issue I had was on the credit card statement, was confusing to have an order from Autoplicity.

Fast service

Everything was fine

Very good price, excellent delivery time and easy website to navigate.
