Found what I needed and processed quickly

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.

So far in the purchasing process prior to shipping ,experience has been quick and painless.

Good experience and prompt

The pads fit right

GREAT PRICE FOR PARTS THANKYOU!
