A 4th-gen (2019+) Ram 2500 Cummins on a Carli Backcountry system clears 37-inch Nitto Ridge Grapplers — they can rub at full lock under compression — while the truck sits level and rides far better as a daily.
A 4th-gen Ram 2500 (2019+, 6.7L Cummins) came into Juggernaut USA in Wheat Ridge (Denver), CO for a better daily ride — not lift. The factory HD suspension rides stiff, and this truck gets driven every day. We installed the Carli Backcountry system with the Carli torsion sway bar, on Method 304 wheels and 37-inch Nitto Ridge Grappler tires.

Why Carli Backcountry and not a cheaper leveling kit?
The owner wanted ride quality, not height. A budget spacer raises the nose and calls it done — it does not change how a heavy HD rides. The Carli Backcountry system replaces the suspension with 2.0 shocks, multi-rate rear springs, a track-bar drop bracket, a sway-bar drop bracket, and adjustable radius arms, so the truck sits level and rides softer while keeping the geometry right for towing. We added the Carli torsion sway bar on top, which tightens body roll without bringing back the harsh factory feel. On a daily-driven 2500 that combination is the difference that matters.
How the install went
Clean. Carli kits are engineered to bolt to factory mounts — no cutting, no fabrication, no fighting brackets into place. That has been true of every Carli install we have done: the parts go where they are supposed to, the first time. It is part of why we recommend them.
Will 37s fit a 4th-gen Ram 2500 with a Carli Backcountry?
Yes — 37-inch Nitto Ridge Grapplers clear on this setup, but not in every scenario. At full steering lock combined with suspension compression, they will rub. On a daily-driven truck that is an occasional tight-turn-over-a-bump situation, not an everyday problem — but it is worth knowing before you run 37s on a Backcountry-height 2500.
Common questions on this build
Does the Carli Backcountry ride better than a stock 4th-gen Ram 2500?
Yes — that is the point of the system. It swaps the factory springs and shock valving for a softer, more controlled ride while keeping the truck level, which is exactly what this owner was after on a daily driver.
Is the Carli torsion sway bar worth adding?
On this truck, yes. It controls body roll without reintroducing the stiff factory ride, so you get the softer Backcountry ride and flatter cornering at the same time.
Does a Carli Backcountry kit need fabrication or extra parts?
No. It bolts to factory mounting points — no cutting or welding. On this truck it went in clean, the same as every Carli kit we have installed.
