This is an awesome auto shop. Straight talking; quality and on-time work, and great value. Thanks Greg! I will whole-heartedly recommend 4wd Xtreme to anyone in need of your services.

Friendly, knowledgeable, reasonably priced. New go to mechanic and fabricator in Longmont for lifted Toyotas.

This shop is terrific. Theyve done two services already and Im happy with both. They did a major repair on the plow truck- rewelded a broken track bar and found a leaking water pump while they had the truck. Ive ask Firestone whats leaking twice and they werent able to find it but these guys were.. well done guys! After some new tie rods and the track bar work the truck drives awesome! Ill bring the truck back for service in the future. Thanks for getting it back on the road!

Greg is probably one of the best mechanics I know. Has done work on my girlfriends 99 Corolla and my 01 Chevy Silverado. Greg and his other mechanic are great and very fair. I always recommend people to him

Brought my Jeep for a big job for freeze plugs, header replacement, frame repair and other work. The cost was far more reasonable compared to other local shops. Greg did a great job and had me back on the road quickly. There was one issue making some intermittent noises. We had a heck of a time getting it to repeat for the shop, but Greg didnt give up and was able to fix the minor issue. He was patient, kind, and understanding every time I called. Has been running great since! I have referred several people his way and I will be back to get some upgrades done this next year. Thanks for your help!!!

Greg and his staff work on all our trucks and our 71 Blazer. There take pride in the work they perform. Always happy with everything they do from brakes to helping restore our blazer. Just really good honest people! Thanks Greg

Ive taken my vehicles there for a long time and Ive recommended them often,

If you want a restoration done or a diesel put in your anything these are the guys to go to

Greg and crew are very knowledgeable and very reasonably priced. I highly recommend them.

Greg and his employees are helpful and will get you back on the road fast and will give you low cost repair options!

Great place for custom Jeeps.
