Cody is a great diesel mechanic specializing in Cummins. He did a rear end swap in my jeep to give me 4.10s. He took his time and made sure everything was working as it should and painted the new housings and made them look great. The jeep crawls as it should now. Thanks Cody!

At Grimm's I've had 2 motors built by Cody Grimm the owner, both very reliable engines with one of them making over 1,000 horsepower.
