When it comes to off-roading, the Jeep brand has been a pioneer for over 80 years. From the original Willys MB designed for the U.S. Army during World War II to the latest Jeep Wrangler models, the brand has mastered the art of navigating tough terrains. The secret behind the Wrangler’s renowned off-road capabilities lies in its four dynamic 4×4 systems: Command-Trac, Rock-Trac Part-Time, Rock-Trac Full-Time, and Selec-Trac. Each system is tailored for specific driving styles and terrains, making it essential for potential buyers to understand their options.
