Best place to get work done on your Cummins! Got my truck timed perfectly on my 94 12v after a shop down the road couldn’t get it done for the life of them! Thank you Rob! Amazing service

Amazing place! Very knowledgeable they know what they are doing. Took care of my husbands truck! And made it right after another shop absolutely didn’t know what they were doing on a 2nd gen 12v. Thank you !

Rob from Maxtorq takes good care of my truck. I drive out of my way to have him work on my vehicle because you can trust them to do the job right.
