Best belt drives and clutches you can buy, 100% American made 100% assembled in U.S.A, staff is knowledgeable and easy to work with. There is only two people manning the phones so its difficult to get through right away but michael is always on the ball getting us customers taken care off keep it up Michael!

This use to be a good company. Now is absolutely terrible. Lousy customer service. Products that have fitment issues and no knowledgeable tech employees. Never answer calls. DO NOT return voicemails or emails. No actual location now other than a mobile phone that goes to someones personal phone. Save your money and use another brand other than rivera Primo

This company does not answer emails or phone calls. I had a set of their pushrods fail prematurely and took out other parts of my engine. All i asked for is a set of replacement pushrods and they cant even give me the common courtesy of a return email or phone call. I recommend not doing business with a company that completely ignores the customer that buys their products.

Rivera/Primo has top quality products and customer service.

Great Customer Service, easy location to find.

Not in Whittier any longer.

Called for 2 days now at multiple points through out the day no one answers the phone.

Great place
