Underdog Motorsports, Mesa AZ

They do an outstanding job. Highly recommended. Best spot in town for any 4x4 related work. Thank you!

These guys are awesome. I read about lift options online for my 08’ 4runner for months, and had a pretty specific need for something a tad lower than standard 3” lift. Brett talked through every combination of options (he came up with alot) and recommended a setup that fit my needs and off-road interests. He even explained in a way I’d understand without too much mechanical knowledge. They even took care to spot some things during installation that needed replacing. You usually pay a lot more for service like this and I couldn’t recommend this shop more. Give them a call before you go anywhere else if you want great service, expert installs, and very fair prices.

Great customer service and pricing on tires for my Rzr. Tires were in within 24hrs from ordering!

Thank you

Brett and team got me lifted and ready for the trail within 72 hours of calling them. Awesome work and good people!

Just a quick Shout Out and big Thank You to Brett Dumais with Underdog Motorsports and Jesus with ProWorks Audiø! Jesus and his team did a fantastic job diagnosising and fixing my Rockford bass amp. They had excellent customer service and amazing turnaround time! I will definitely be using them again when I am ready to upgrade my system! Also, a huge thank you goes to Brett at Underdog Motorsports for pointing me in the right direction to go with Jesus and his team!

Brett and Underdog Motorsports are as good as it gets. Honest fair experienced and super knowledgeable. Thank you

We have had a few business transactions with Underdog Motorsports and the owner Brett has taken great care of us and did an excellent job on our UTV! He installed our new Rugged Radios with a custom quick release antenna mount, proper placement of the headset hanger, and relocating a couple of switches along with the install of the Rugged Radio system itself. He even fixed some improper wiring done by a previous shop for free. Underdog Motorsports is an excellent, competent, knowledgeable, and professional off road parts and accessories shop. They do any job that an Off Roader requires. Trucks, Jeep’s, UTV’s, Sand Cars, etc. We also find Brett to be a caring person who takes pride in a job well done. He answered all our questions and spent quite a bit of time going over our new Rugged Radio system. He even helped us load up and tie down our UTV on our trailer for our long trip home. We were so impressed with Brett’s attitude and professionalism in our previous business dealings we did not have a problem driving all the way to Mesa, AZ from Prescott Valley, AZ because we knew he would take good care of us and our off road needs. His prices are fair and reasonable, his shop is tech savvy, and he has a variety of payment options to fit any customers needs. We are very happy with our Rugged Radios and with Underdog Motorsports! Thank You Brett for taking such great care of us! We fully recommend Underdog Motorsports to all future customers! Enjoy!

Awesome shop and fantastic prices!
Knowledgeable sales and professional installations without the "big box" off-road motorsports shop feel.
Well done guys, highly recommended
Grade: A

Did an extensive research prior of getting my Jeep to them and spoke with quite a few Jeep pros and visited 3 different outfitters, pricing was more for less the same, the big differences was the parts and accessories underdog suggested. While the big shops provided the basic items for the same price and then upsell for better components, Underdog offered top of the line parts from the get go. The also did not always accept my research and parts request and made sure to correct me when I was wrong or clueless, calling dealer in my presence and checking facts. I cannot say enough on how professional they are and the quality of their work. Small shop with huge results.their hourly rate is more then reasnoble, could not be happier with the results. Thanks Brett and Sean for an outstanding project outcome!

Brett's place is excellent!
They know EXACTLY what they are doing and what they recommend is correct.
They have a ton of experience.

Affordable, fast and great prices! Shane is the best mechanic in the valley and Brett does his best! Highly recommend.

Went to Brett to have him install 2 new adjustable upper control arms, OME springs, and icon AAL on my truck. He was able to save me some money as well and reused my bilstein 5100's. I love the lift on my truck. It used to squat with the camper shell and now it does not. And the ride is night and day compared to what it used to be. Thank you Brett! I will say Brett does very quality honest business. He won't try and sell you a bunch of extra stuff you won't need. If your looking for anything honest and quality, hit up Brett with Underdog Motorsports.

Brett and Shane took great care of us getting my Wife's mom-mobile looking and riding good!

They got us into some Bilstein 5100s to help level it out a little better. The ride quality has improved vastly over the GMs "premium ride" package which actually equals bouncy and terrible dampening.

Very happy with Brett's shock recommendation! Thank you guys for getting us set-up and taken care of!

Brett at Underdog Motorsports is an honest and standup guy. After getting the runaround from another shop in town, I went online in search of a place that would provide a quote and stand by it. Brett reached out almost immediately and not only provided a quote but made a recommendation based on driving and off road needs. When I went to pick up the Runner, Brett took the time to show off their work, went through what was done and talked about follow-up as well as other suggestion to compliment the lift in the future. I would definitely recommend Brett and Underdog to anyone. Great experience on my end and i’ll be back for sure!

Brett & his team at Underdog Motorsports ROCKS!

They installed a Rugged Radio System in our Can-Am…. Not only did they get it completed before our weekend ride, but they did a super professional job.
It looks super clean & mounted very well!

Brett even came in on a day they where closed to make sure we had our ride as promised!

The radio worked great & elevated our riding experience with other cars!
