There Is No G in Cummins

Our Petersen’s 4-Wheel & Off-Road Ultimate Adventure is a torture test, so it is wise to bring every spare part you might possibly need to keep your rig moving. One thing we leave at home since converting to Cummins R2.8 engines is spark plugs. While the 6BT and 4BT Cummins engines are legendary, their size and weight make them less than ideal swap candidates into smaller 4x4s. The R2.8 solves those issues and comes with everything necessary to run right out of the box. Just add a battery and diesel fuel and go. The Cummins Repower program has a long history with 4-Wheel & Off-Road, dating back to past projects like the 5.0L Cummins-powered Off Road Runner and Project Tube Sock, the latter of which famously ran underwater for 45 minutes.

Last year we slung an R2.8 Cummins turbodiesel into our CJ-6D, and this year we fit an R2.8 between the framerails of our DeRange Rover. UA crony Dave Chappelle even drove an R2.8-powered JK backed with an eight-speed ZF automatic this year. The compact R2.8 Cummins turbodiesel has 310 lb-ft of stump-pulling torque, making it a perfect match for Jeeps, Land Cruisers, Range Rovers, and more. With an R2.8 the spark plugs aren’t the only thing you can leave at home. These engines are so reliable they handled everything the Ultimate Adventure threw at them while sipping fuel and running cool all day long.
