Most heavy-duty truck builds force you to make a compromise. Bigger tires, more lift, and a more aggressive stance often come at the expense of ride quality, steering performance, or towing capability.
This GMC Sierra HD build takes a different approach.
In this video, I walk through my OEM+ build philosophy and break down the upgrades that transformed this truck into the ultimate daily driver, tow rig, and adventure vehicle. We start with a complete overview of the Cognito suspension package, including the front suspension, steering upgrades, and rear suspension components that help this truck handle 37-inch tires while maintaining excellent road manners.
From there, we take a closer look at the all-new Nitto Tire Terra Grappler G3 in 37x12.50R22. I'll cover why I chose this tire, how it compares to other all-terrain options, and share my initial impressions on ride quality, road noise, handling, and towing performance.
If you're considering upgrading your GMC Sierra HD, Chevrolet Silverado HD, Ford Super Duty, or Ram HD, hopefully this video helps you decide whether the Terra Grappler G3 and an OEM+ suspension approach are the right fit for your truck.
