2017 Jeep Wrangler Sahara JK (Silver Jeep)

2017 Jeep Wrangler Sahara JK (Silver Jeep)

Our Sahara JK is a great option for those looking to adventure on lighter, less technical trails — if you’re an off-road first-timer, this rig will do you and your group just fine. Compared to our Rubicon, the Sahara is a softer, more comfortable ride due to its 2.5” Progressive Rate Spring Lift. 

But despite the relative comfort in the Sahara, don’t underestimate its capability. It’s a beast of a rig and it will handle many trails with ease!

2018 Jeep Wrangler Rubicon JL (Red Jeep)

2018 Jeep Wrangler Rubicon JL (Red Jeep)

The word “Rubicon” is commonly slapped onto stock Jeeps, but the name holds an off-roading prestige of its own. Named after the iconic Rubicon trail in California, these Jeeps come trail-ready in accordance with their off-road pedigree. But of course, a stock Rubicon wasn’t enough for us to offer you a proper off-road Jeep rental.

That’s why we’ve outfitted this Jeep with a 3.5” Rubicon Express Coil Lift for supreme clearance to tackle some of Colorado’s most demanding trails. This bad boy also features a 4:1 transfer case for low range rock crawling, an essential feature when you’re truly putting your driving skills to the test.


  • Rubicon Express 3.5” Coil Lift (4.5” on non Rubicon Models)
  • Rubicon Express Fully Adjustable
  • Extreme Duty Long Arms Front and Rear
  • Rubicon Express 2.5 Series Shocks
  • Fox Steering Dampener
  • Electronic Lockers Front and Rear

John’s 4x4 Jeep Rentals — Where Will You Go? 

Life is too short to miss out on exploring the stunning Rocky Mountains and network of trails right in our backyard. Our fully-built, trail-ready rigs can take you to that dream camping spot or hiking trail, give you a taste of the true off-road experience, and take you to epic vistas that you could never reach in a standard vehicle. 

At the end of the day, we’ve worked hard to outfit our Jeeps with the latest and greatest upgrades to ensure that even the most novice off-road drivers can experience what we love most: getting outside and exploring!

A Note On Safety

John’s 4x4 is proud to help the community connect with the outdoors through our 4x4 Jeep rental service. However, it’s important to note that off-roading is inherently dangerous (but totally enjoyable when practiced safely). The possibility of rolling over, bottoming out, or causing extensive damage to your Jeep is very real, and you don’t want to be stranded out on a trail with no cell service and a way to call for help. 

You’ll find that other off-roaders on trails, should you encounter them, are very nice people willing to help you out. But it’s important to know exactly what you’re getting into and how to navigate trails safely and effectively. 

These resources will be very helpful in making sure that you’re trail-ready: 

Ultimately, our goal is for you and your group to have a safe, fun, and epic adventure exploring the beautiful Rocky Mountains. If you have any questions, please contact us in Boulder or book your Jeep rental today!
