As far as dual-quad manifolds go, it's hard to beat the cool factor of the tunnel-ram and cross-ram setups; to see which makes more power, the guys bolt each to the 383 Chevy and stagger jets until their gasoline-soaked hearts are content.

The guys see which muffler works best for street-driving 1,000 HP monsters.

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

The custom Jeep JL gets a drivetrain after Ian finds a junkyard LS engine to install, later he fabricates the exhaust.

The chassis on the Jeep JL is powder coated before Ian bolts everything in place and fabricates the body panels.

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

The crew works on wiring, plumbing, body panel installation and the interior on the buggy; Ian hits the trails in a custom Jeep LJ.

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 crew focuses on what the Polaris will need to stay safe on the trails; Ian customizes a roll cage, installs the driver's seat and adds some tunes.

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.

Ian moves weight around on a Samurai to get more squat in the rear end, shifting the radiator and fuel cell and changing the rear end suspension geometry to help this rig better handle the rocks.

Ian goes on an adventure with some of his buddies, hitting a few off-road parks nearby, making some roadside repairs, and ending the trip with some Tennessee whiskey.

Ian brings back the Suzuki Samurai, this time for an old-fashioned engine swap; he's going to take out the mechanical four-cylinder diesel VW engine and upgrade it with a common rail VW diesel.

Ian's LJ Buggy has seen plenty of rocks and off-road tracks, and he already knows how to improve the vehicle. He rebuilds a dash, adds headlights, and redoes the steering and exhaust.

Ian demonstrates how to stretch a JK 10 inches.

The JK stretch project is back from the body shop and is ready for an all-new suspension and axles; Ian will get some Dana 60s under the rig with 40-inch tires and see how it performs by hitting some rock hills.

Ian wants his Nissan Titan to tow his new Tracker side by side, so he needs to outfit it for towing; he bolts some off-road parts onto the side by side.

The Ram Charger is ready for the trail with a new engine and drivetrain, but it needs to be outfitted for overlanding, so Ian builds out the interior for camping, adds a solar panel roof rack and builds a custom front bumper.

Ian needs a new Four Wheeler shop truck, but he doesn't just buy new trucks, he builds them; he'll tear down a two-door Dodge Dakota and turn it into a custom tools-carrying monster.

Work continues on the Shop Truck Dakota; Ian works on the drive-train components, including a complete transmission teardown and rebuild; plus, he shows what it takes to completely rebuild the axles.

Ian finds the perfect service platform for a truck and cuts it in half to fit; he finishes the design with a custom paint job.

Ian gets invited to ride in the 2020 Ultimate Adventure; he and a group of off-road enthusiasts drive thousands of miles on-road and off-road.

Ralph and his team design a 1969 Ford Bronco for SEMA; a 1960s Volkswagen Bus is transformed into a conference area for a tech company, but delivering the vehicle to the client may prove to be the bigger challenge.

Ralph and the team restore a classic 1962 Lincoln Continental convertible and update a 1956 Chevrolet Bel Air to take to the annual Barrett-Jackson Auction in Scottsdale, Ariz.

The team restores a 1957 Ford Thunderbird for a client's wife; a 1961 Chevrolet Impala receives a new LS3 engine and custom headers.

Ralph wants to transform a rusty 1951 Chevy into a Rat Rod; Victor and Eddie convince Ralph to change the design and give the vehicle a full restoration.

Ralph builds a 1958 Chevy Apache from the ground up for a potential buyer; with only the shell of the truck remaining, the team builds a custom exhaust system, adds a unique leather interior and customizes the paint job.
