Client Testimonials

I have been coming to Independent for a while now and won’t go anywhere else. They are the only shop I trust. Have been worked over many times by other outfits but when I go to Independent, I always know what I’m getting. No scams, no false promises, just great engines with genuine components, every time.

I have had many engines remanufactured and/or rebuilt but this company exceeded anything I have seen in the past. The quality of their work is truly unmatched. My engine ran like new with all genuine CAT parts ordered right from the dealer. Haven’t had a problem since and I will definitely be using them from now on.
