If it has wheels and goes off road, Ian Johnson will work on it! In FourWheeler we work on everything from upgrading your daily driving Jeep, to building a custom tube chassis rock crawler. Ian takes you along for the "do it yourself" ride as we tackle everything from simple "bolt-ons" to full on fabrication.

FourWheeler Full Episode Guide

  • Ian goes on an adventure with some of his buddies. They hit a few off-road parks nearby, make some roadside repairs, and end the trip with some Tennessee whiskey.

  • Proper weight distribution is essential out on the trails, but sometimes it's hard to know what can be moved and how to do it safely. Ian explains what to look out for to tackle the trails without getting stuck.

  • An '80s Ramcharger is back in the shop for an engine swap. The owner wants a gas-powered Hemi, so Ian swaps the old, tired engine for one from a local junkyard.

  • With the drivetrain and suspension done, its now time to focus on what well need to stay safe on the trails. Ian customizes a roll cage, installs the drivers seat, and adds some tunes.

  • Ian doesn't want to fix a beat-up Polaris XP 900. He wants to turn it into a completely different rig. He decides to stretch the side by side and add longer suspension for more travel, but that's just the beginning.

  • The buggy is nearly finished. Its back from paint and all that remains is wiring, plumbing, install the body panels, and the interior. When hes done, we are ready to hit the trails in our custom Jeep LJ.

  • Larger tires on an off-road rig usually mean broken axles. A 1989 Dodge Ram Charger is in the shop, and Ian shows how to swap out a semi-float axle for the more desirable full-float axle.

  • The chassis on the Jeep JL has been powder coated, so now it's time for final assembly. Ian will bolt everything in place and fabricate the body panels just in time to send it all to paint.

  • The custom Jeep JL gets a drivetrain after Ian finds a junkyard LS engine to install. He also fabricates his own exhaust.

  • Ian begins assembly of a custom LJ chassis and builds a full Jeep out of a pile of metal tubs. Then he adds front and rear axles with cut-to-length control arms, and finishes off the build with coil-over suspension.
