Mud-Covered Thrill Seekers

The term “swamp buggy” evokes images of mud-covered thrill seekers attempting to conquer wet and sloppy terrain in purpose-built, Mad Max-like mud machines. Typical builds in this segment include custom ATVs, UTVs, 4x4s, and other one-off vehicles designed to power through water holes, deep swamps, and viscous mud.

At the heart of this swamp-traversing, people-moving platform is a 5.9L Cummins 12-valve turbo diesel. The engine has a devoted fan base in the off-road and diesel communities. Its high torque output is ideal for churning through thick mud, deep water, and other swampy conditions.

As one of the most beloved diesel engines, the 5.9L Cummins 12-valve platform is known for its reliability and ease of modification. It’s a practical engine choice with readily available replacement parts. It’s also ideal for custom builds, especially those that must withstand heavy loads and harsh conditions.

Added Boost

The Cummins in this buggy was upgraded with a Holset turbocharger and a large intercooler for more boost for heavy load conditions. High-performance Bosch diesel fuel injectors optimize fuel delivery. A custom-fabricated snorkel air intake system ensures the engine breathes clean, dry air in the deepest of conditions. An A518 transmission with a transmission cooler delivers smooth shifting and increased reliability.

Holset turbo and intercooler

The swamp buggy’s platform was custom-built for strength and functionality. It has a visually striking powder-coated frame, rear step ladder, and railings that resist rust and corrosion. The 12-passenger seating arrangement uses Summit Racing bucket seats and lap belts with a focus on passenger safety, comfort, and accessibility.

The custom-built dash and steering console are equipped with AutoMeter Phantom gauges for clear, reliable driver feedback. The B&M ratchet shifter is functional and cool. Rockwell 2.5-ton axles are ideal for powering the buggy’s massive Firestone Champion Spade Grip tires mounted to custom-fabricated wheels. A Wilwood disc brake system adds premium stopping power, which is especially critical when fully loaded with passengers.

Nighttime Adventures

Visibility and safety are critical when mudding, especially after dark. LED light bars on all sides provide added illumination during nighttime adventures. And because music improves any social gathering, a Bluetooth speaker system will keep the atmosphere as lively as the terrain.
