A REFERENCE TO CAR MODEL AND YEAR WILL BE A GOOD REMINDER OF CORRECT PART ORDERED

I recently found THMotorsports while searching online for Gates brand radiator hoses and heater hoses for my 2008 Corvette. Excellent prices. Less expensive than NAPA (which sells the exact same Gates hoses). I like that live in-stock inventory counts are shown on the web-site. If the Free Shipping is as fast as stated ("usually delivered within 2 days"), then I will definitely consider THMotorsports for future automotive parts purchases.

Great service

It was fast and easy.

Great

I could not change the shipping address. 2142997345

Unless i get notified that "oops we're actually out of that product" or something like that (which usually happens) i'll be happy as a clam.
