John's 4x4 - Boulder, Colorado

Français en voyage, nous avons un problème de suspension arrière. On voulait l'avis de ce garage spécialisé 4x4. A savoir si notre problème vient des suspensions ou des ressorts. Et on nous a dit qu'on ne pouvait rien faire pour nous.
Je ne recommande pas ce garage... soit-disant spécialiste 4x4 !

The team at John’s are incredible. They did awesome work on my 2025 Land Cruiser with a lift and suspension upgrade. They were super easy to deal with and no pressure. On top of that they are extremely knowledgeable about off-roading equipment and practical applications.

John’s 4x4 did a great job on my clutch replacement. Kevin E was very knowledgeable and great to work with. I would recommend John’s 4x4 to anyone wanting to get work done on their Jeep.

Very satisfied with the work Austin and his team did on my truck. It was a good sized job involving front and back diff re-gears, fitting 37" tires, carli long arm suspension and adjustable track bar, upgraded steering box... and more. Austin updated me throughout the whole time my truck was being worked on, sent lots of pictures to make sure I understood what modifications were necessary to make everything have proper fit and function. Johns 4x4 will get your rig exactly how you want it at a very fair price. Great guys to work with!

John’s 4x4 did a great job on my Subaru Forester lift. We ran into an issue with the manufacturer sending the wrong parts. Kevin was my advisor and he pressed them to resolve within 24 hours. The build looks great, and I would highly recommend John’s 4x4. The pic shows a stock Forester next to mine!

I cannot speak highly enough about my experience with John's 4x4. From the moment I first exchanged messages with Austin about fly fishing, the dedication to quality and expertise was evident. I recently had John's 4x4 install Dobinsons MRR suspension lift, heavy-duty leaf springs and coils, along with some gorgeous (but not flashy, they're rims not fishing lures) Method Wheels with Mickey Thompson Baja Boss rubber(All by Austin's suggestion, btw) on my Tacoma TRD Off-Road, and the transformation has been nothing short of exceptional.

Before visiting John's 4x4, I had never heard of Dobinsons and was initially hesitant to venture into unfamiliar territory. However, working with Austin changed everything. His knowledge and genuine passion for quality made me trust his recommendation of the Dobinsons MRR suspension, and I can confidently say it was the best decision I could have made.

Austin took the time to understand my needs, considering both rough Alaskan backcountry terrain the vehicle would see throughout the summer mostly, and the daily city driving requirements of being a general contractor. The flexibility of the MRR suspension, which can be easily adjusted, sealed the deal for me. Although the wait for the parts from Australia was longer than I anticipated, the end result was well worth it.

If I could make any changes, it would be to have Dobinsons located closer to home, and, well, same with John's 4x4. Unfortunately I was unaware they were located about an hour from home. But, despite the distance, the team at John's 4x4 went above and beyond by providing a loaner vehicle and ensuring a nearly seamless experience. Their expertise and personable approach truly set them apart.

In a nutshell, John's 4x4 exceeded my expectations in every way. The improved ride quality and performance of my truck speak volumes about the craftsmanship and dedication of this exceptional team. I wish I had more time to really sit down and aknowledge several other positive aspects, but I think you guys and whoever else might be reading this, gets the point. I highly recommend John's 4x4 to anyone looking for top-notch 4x4 upgrades and outstanding customer service. Do you and your truck a huge favor and call John's before you call anywhere else!

Thanks a ton guys. I get compliments everywhere I go on how incredible my truck looks. I could not be happier with it. Sincerely, thank you... and, I don't have to make 2 trips to haul tools anymore!

I just wanted to take the time and share my appreciation to John’s 4x4 in Boulder, Colorado. My primary contact, Kevin not only kept me updated on every step of the process, but when they ran into an issue with the lift kit that was installed on my truck when I bought it, they could have just put on the new parts and gave it back to me knowing that the issue would return if it wasn’t corrected properly. Instead, they researched the lift that was on my truck and called that 3rd party to tell them how it was wrong and that company confirmed they knew about the issue and sent the correct parts.

If they take this kind of care and attention to detail on a 3rd party lift they don’t even sell, what kind of support do you think they would give to those lifts they DO sell!

Thank you Kevin and crew! I wish I would have got the lift from you guys, but I will have all my services done with you guys now!

I highly recommend Johns 4X4. They took excellent care of me and my JK. They ACTUALLY did a proper 4WD alignment and afterwards, sent me off with some advice on correcting some minor issues on my own without trying to "build a bill" for the sake of making extra money. I really appreciate their expertise, honesty and quality of work. The pictures and updates they shared in the invoice platform also makes understanding the work performed and recommendations they make extremely easy to digest and go back to and read at a later date. Bring your 4WD vehicle here, they are experts! My service advisor was Terrell and he was a pleasure to work with, thanks for all the help!
