Had a bunch of suspension issues with my truck, these guys did a great job. The inspection was very detailed and costs were laid out and easy to understand. Quick turnaround on the work and good communication. I will definitely be bringing my vehicles here in the future.

Had them install a Rallitek overload spring upgrade on my 2024 Forester but the experience didn't go well. The rear springs they installed were making a clanking noise when going over potholes and John's 4x4 (now REV Outfitters) attempted to fix that multiple times but failed. Then they just stopped returning my phone calls, so I had to fix fix the problem myself. And after my last visit, the alignment, that I was told was spot on, was so far off that my steering wheel was crooked as I drove straight down the road. That was confirmed by another shop (at my expense) that used a new, state-of-the-art alignment rack. For the top-dollar amount charged by John's 4x4 and the hassle of having to go back four times and still not getting a positive outcome, I wish I had chosen a different shop. Overall, I am not happy with the result.

Very professional team. I had concerns with necessary parts for my lift and Kevin helped me verify it would all work. No issue and my truck drives much better now with the dobinsons suspension under it.

Have been there numerous times for small and big jobs on my truck. Each and every time the guys have been absolutely awesome getting my truck in and out of the shop on time and in immaculate condition. Just recently had all new tires put on my truck as well as some work done with a broken lug and everything turned out great!

Recenlty took my 2020 Rubicon to REV outfitters to diagnose a problem. I am newer to having a jeep with a lift and aftermarket parts. Terrell helped me through the whole process of getting quite a bit of work done and really explaining everything to me. Extremely helpful and patient! I cannot say enough great things about my experience and the work I had done here. I am very pleased with the new long arm kit they installed. Highly recommend Terrell and the guys here!

Awful experience. Overpriced. Very low quality work. I brought my 1993 Jeep Yj to these guys about a week ago. I specifically said I could smell a burning smell from the rear tire, wanted them to look into fixing parking brake, and fixing the 4x4. A week later I spend over 1k on a custom driveshaft, 700 on replacing the front wheel bearing and 250 to install tires ( not aligned and didn’t even wipe off the paint stickers). I get there because it’s “ready” they don’t even mention the burning smell and have said nothing about the parking brake. I ask Terrell who says the parking brake will be a few thousand because of my jk axle. Okay well why didn't you put it on the invoice before I drove 40 mins? I just spent 2k so it’s not like I don’t have money. I ask about the burning smell, nobody knows what’s going, no inspection on it, just a guess that it may be rear brakes. Okay so, what am I supposed to do with that? On top of this they accidentally overcharged me for something else. And on top of all that I am pretty sure there courtesy checks are jokes. The owner before me put ziplock bags as caps for certain elements under the hood. Not a single mention of that at all but they said my wipers are bad so hey maybe that’s the extent of their check. Now my car is another shop. I would not go here unless you absolutely have to or you enjoy throwing money away.

Just had some upgrades done to my 2024 Lancruiser by John's 4x4 of Boulder, CO. A new roof rack, skid plate, and a full coil-over suspension (Icon Stage 6 /w reservoirs). Excellent work everywhere! A true pleasure to work with them!

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!

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.

Awesome place! Professional and friendly staff that obviously care about doing things right. I came in with a Santa Cruz to get a lift. It's a little baby truck that has no right to call itself a truck. When I dropped it off, I saw all these other off road monsters that were glorious and ready to go on adventures. My Santa Cruz looked pitiful next to them. The staff could have laughed about me getting a lift, or even given me a hard time (good natured) about the pitiful size of my "truck", but they didn't. They treated me with respect, kindness, and best of all- they did a fantastic job. For anyone looking to get their monsters upgraded, this is the place. And for anyone who just wants to pretend their truck is more badass than it is, well, they got you covered as well. Amazing team that was positive and friendly from the start. Highly recommend!

I am a big fan of Johns 4x4 REV outfitters. They have been maintaining and modifying my wives 2015 Ford truck and my daughters 1995 Cherokee for the last 5 years. Smart recommendations and quality work!

Kevin and Austin were great, and so were the techs that took care of my truck. The inspection was straightforward, they were transparent about the recommendations, and Kevin took the time to go over the details and also school me on some of the questions I had about the truck. Overall I'm very satisfied with the repais and will be taking the truck back to them should I run into any other issues. Thanks folks!

These guys rock. They’ve been the coolest modification shop to work with. I have many more mods planned for my rides and it’s going here. Shoutout to Isaac for continuing to hook up the rides perfectly.

Went here to get a winch on my bronco. Isaac talked me though options, pros/cons, and came up with something great. They found some other issues while working underneath, called me up for guidance and got everything squared away. Even offered to reinforce some areas so it doesn't happen again. Great comms, great work, will go again.

I've been to Johns 4x4 several times for work on my Tacoma. They got me out of a jam the dealer put me in. They installed a Dobinson's lift kit, replaced my steering bushings, and properly aligned my vehicle. Most recently they installed some RCI rock sliders. Kevin is best. All proposed work is explained and different options are discussed. I trust these guys completely and highly recommend their work.

These guys serviced and repaired my 2001 diesel 4x4 f250 7.3 power stroke. Isaak upfront was professional, personable, and provided transparent communication throughout. Cameron, the mechanic, made it a point to speak to me personally upon pickup. High quality service, honest, and most importantly-a very high level of integrity which seems harder and harder to find at a shop these days. Thank you everyone involved in my truck repairs.

A big shout out to this team. They listened to my vision, gave me choices. and I could not be more pleased with how it came out. My advisor Izsak worked through supply chain issues, and went out of his way to bring my Jeep to my house after hours when I was not able to pick it up myself just before a holiday. Super customer service. John's 4 x 4 & REV Outfitters will be doing more work for me in the near future to finish my build. Step 1 complete!

This was clearly a professional outfit. The shop was highly commutative during maintenance. They replaced my steering gearbox with a red top and installed a steering stabilizer after a quick inspection. I recommend these guys. Especially if you have a passion project you’d want kept in good hands.
