Testimonials

LightForce - Nathan H.

"Due to your speedy service I was able to take the new lenses (LightForce) into Canada with me this last weekend.  They definitely work great and helped me avoid a moose."

EDGE and AFE - Wade H.

"Previous to my modifications, I got 10.8 mpg on the last tank in my 2002 Ford F250 PSD. Then along came Grimm Performance!

As you will recall, I purchased the Edge EVO and the AFE Magnum Stage II. In addition to these upgrades, I added the Magnaflow 5" SS Exhaust. I got 21.47 mpg on my first tank with the EVO set on TOW!

I just wanted to say thanks for your help. You have a new, very satisfied customer."
