Diamond Performance no-hassle guarantee!

Isn’t it annoying when you pay for something, and then it doesn’t work or it breaks after you bought it?

Even worse, when you contact the company who sold you the product, they don’t do anything to make it right.

They simply shrug it off, mumble a meaningless apology, or worse yet, they make it sound like it was your fault!

You’ll never be treated that way in dealing with us!


We offer a no-hassle, lifetime guarantee on all product lines we sell!

And when we say no-hassle, we mean it! If you have an issue with any diamond Performance product we provided, this is what we’ll do:

  • If our products break or fail, in any way, due to a manufacturing defect or natural wear and tear, we replace it at no cost to you, period!
  • Simply send us a picture of the failed product and we’ll immediately ship out a replacement ( zero shipping cost to you! ), and that’s how we offer a truly hassle-free guarantee.


We stand by our products with what we believe is the best No Hassle Guarantee in the world!

Your call is important to us!
Most companies make getting a replacement under warranty difficult just because they won’t answer your call, email, etc.

At Diamond Performance, that’s never the case!
