First time customer and very pleased with price and service.

The only issue was the shipping straps on both shocks were broken on one end only! Made it more difficult to install! But for the price I can't complain much! Thanks

I found the site affordable, easy to navigate, and fast shipping

Shipping was a bit expensive. Sure you folks didn't have anything to do with that. Would use you again.

Awesome experience! Thanks!

Excellent customer service, fast shipping and good quality products. Thank you Boatplicity Team

This was good price for a great tire!

Great service
