Xtreme 4x4 - Season 7

Ian and Chris adapt an IFS cantilevered racing style suspension to our curvy buggy with custom fabrication on the Rockwell axles front and rear. Plus, the buggy gets full hydraulic steering front to back with joystick control, then strip it for paint.

Sitting almost 3 years, the portal axles are out, Dana 44 and Chryslers are in! Our Pathfinder is transformed from shop eyesore, to a capable street/trail rig to carry our TV crew beyond the trailhead, and up the rocks. Massive power inverter included!

In 1988, when GM redesigned their pickups and SUV's to a more rounded-style, and for a more comfortable ride, a lot was lost in the wheeling department! We take a full-size Blazer, and rip out the independent front suspension for a D60 solid axle swap.

Our stock JK is Xtreme worthy after we add body protection, speed sensor mod, snorkel and more. Then we'll see just how close a supercharger can come to the performance numbers of a 5.7 ltr Hemi mod, when we put both on the dyno!

With an "over the top" project like our Curvy Buggy, why settle for stock diesel performance? We tear apart our 6.6L Duramax and borrow pulling truck technology for a complete bottom to top end rebuild of the diesel, then get numbers off the dyno.

From "maller" to "crawler!" Our '94 full size Chevy Blazer is transformed into a hardcore trail truck with beefy bumpers, winch, rear tire carrier and more. Plus how-to install radius arm front with coil over shocks and rear leaf spring suspension.

Our Low Dollar Wheeler Cherokee is back for tips on an easy no-cost locker. Plus our Blazer gets an engine rebuild, plus a roll cage and more.

The Green Samurai fun buggy returns for a list of drivetrain upgrades, including new gears, lockers, axle housings and more.

Everything you need to know about the tough, reliable (and affordable!) 14-bolt axle. We modify ours to increase ground clearance and reduce weight. We upgrade the internals, too. Front-steering and rear-engine applications are also covered.

The belly of this beast is anything but soft! We upgrade the undercarriage of our dual-purpose Blazer with a stronger transfer case and stainless steel exhaust. And underneath the shiny, new cowl-induction hood: enhanced air intake and ignition systems!

Although it's strong, precise, and versatile, TIG welding remains a mystery to many off-roaders. We take the guesswork out of TIG work, with detailed information for steel and aluminum welding. Plus, we look at setups for all budgets and backgrounds!

Viewer designed, Xtreme built! Thousands of viewers took the online poll to help us build our new buggy. Starting with a pre-made chassis, we use the poll results and begin a one of a kind Crawler! Plus, our Cherokee gets an upgraded transfer case.

Your wish is our command! The Blog Buggy continues, based on the results of our viewer poll. We add a custom-fabricated engine guard, winh, gas tank, radiator and more! Plus, we paint our Low Dollar Cherokee on a truly tight budget: 25!

The last time we wheeled the 1991 Toyota Xtra Cab at Mayhem Off-Road Park, mechanical failure cut our day short. Today we seek our revenge, with the help of tough 1-ton axles, 44" tires, and a custom link suspension. Boulders, beware!

After a solid axle swap, upgraded engine, and many other improvements, our dual-purpose Blazer is ready to roll! We'll test our rig's performance on the road... and in the woods. From highways to hills, we're ready for any terrain that comes our way!

The goal: turn a worn-out Jeep Cherokee into a capable trail rig. The budget: $5,000! With one eye on the pocketbook, and one eye on performance, we upgraded our suspension, drivetrain, tires and more. Today, we take our XJ out for a test run!

Expedition trucks travel to some truly remote and scenic places, carrying all the provisions for food, water, and shelter. We begin our Jeep WJ Expedition project with updated suspension and axles. Plus, we take an expedition trailer on the trail.

Fresh out of the box, your shocks may perform at 80% of their potentional. But finding that last 20% can make a huge difference! Using a Blazer and a tube buggy as examples, the shock experts at Bilstein show us how to get the most out of our rides.

We are rounding the corner on the Blog Buggy! The viewer's choice crawler gets hydraulic steering, seats, lights, and more. Our rig is almost ready to wheel! Plus, we examine which type of fluid line works best for your specific application.
