You love your Jeep — and at John’s 4x4 and Rev Outfitters, we’ll provide it with the care it deserves.

Let’s face it...Jeeps are different. They get used differently, they perform differently, and they require different repairs. They also demand modifications to perform even better. Having the right Jeep repair shop is essential!

Jeep Repair

60-70% of our customers are Jeep owners. We perform regularly scheduled maintenance and routine repairs, conduct in-depth diagnostics leveraging Chrysler’s Wytech software (same as dealership). Our technology enables us to perform flash updates, install new electronics and computer parts, and identify root causes much faster.

Trail Jeeps

For the jeep owner that uses their jeep to explore and run trails, we know how important performance and capability is to them. We not only install high quality aftermarket suspension, axles, steering, and protection, but we also perform custom fabrication to meet your needs. From gearing, to axle housing and suspension modifications, to chassis fabrication.

Vintage Jeeps

Jeeps are our matter what year the jeep it is. We have performed work on Willys Jeepster, M series, SJ and wagoneer series, CJ’s, YJ’s, XJs, and more. If you have a vintage jeep that you want to maintain, modify, or restore, let our Jeep experts take care of it for you.
