There are trucks built to work...and then there are trucks built to work in absolute comfort while turning heads everywhere they go. This 2020 Chevrolet Silverado 3500HD High Country is exactly that.
If you've been searching for a clean, low-mileage, tastefully upgraded Duramax dually that hasn't been abused or loaded down with questionable modifications, your search ends here. This is an exceptionally clean two-owner Texas truck that has obviously lived an easy life and has been meticulously maintained throughout its ownership. From the moment you walk up to it, it's immediately obvious this isn't your average work truck. It has the appearance, ride quality, and luxury of a premium pickup while still offering the incredible towing and hauling capability that has made the Duramax/Allison combination legendary.
Powered by Chevrolet's proven 6.6L Duramax Turbo-Diesel V8 producing an incredible 445 horsepower and 910 lb-ft of torque, paired with the Allison 10-speed automatic transmission, this Silverado delivers effortless acceleration, exceptional towing confidence, and one of the smoothest powertrains available in today's heavy-duty truck market. Whether you're towing a large fifth-wheel RV, enclosed race trailer, horse trailer, equipment trailer, or simply looking for one of the nicest daily driving diesel trucks available, this High Country is equally at home doing all of it.
Our service department has completed a comprehensive inspection and service, and we're proud to say this truck needs absolutely nothing. It starts instantly, idles smoothly, shifts flawlessly, tracks straight down the road, and performs exactly the way a properly maintained Duramax should. Simply put—it's turn-key and ready for its next owner.
Professionally Upgraded With Premium Cognito Suspension
One of the biggest highlights of this truck is its professionally installed suspension system.
Rather than installing an inexpensive spacer lift, the previous owner chose one of the most respected names in the diesel suspension industry—Cognito Motorsports.
This Silverado has been upgraded with the Cognito Performance Leveling Kit, engineered specifically for the 3500HD platform to improve ride quality, front-end geometry, suspension travel, and overall handling while maintaining factory towing characteristics.
The suspension package includes:
Cognito Performance Leveling System
Cognito Heavy-Duty Upper Control Arms
FOX 2.0 Performance Series Front Shocks
FOX 2.0 Performance Series Rear Shocks
The FOX Performance Series shocks dramatically improve ride quality over factory suspension by providing better damping, improved control over rough roads, and increased stability whether the truck is empty or towing a heavy load.
The Cognito upper control arms further enhance suspension geometry, improve wheel travel, reduce premature component wear, and provide a tighter, more controlled steering feel.
The end result is a truck that rides noticeably better than stock while maintaining excellent towing manners and an aggressive stance that looks exactly the way a heavy-duty truck should.
Aggressive Wheel & Tire Package
Perfectly complementing the upgraded suspension is a fresh set of:
33x12.50R17 Nitto Recon Grappler Tires
The Recon Grappler is quickly becoming one of the industry's most sought-after hybrid all-terrain tires because it bridges the gap between a traditional all-terrain and a mud terrain.
Benefits include:
Aggressive off-road appearance
Excellent highway ride quality
Minimal road noise
Outstanding wet-weather traction
Excellent tread life
Superior towing stability
Exceptional off-road capability
The wider stance created by the Nittos and Cognito suspension gives this High Country an aggressive look without sacrificing drivability or comfort.
S&B Cold Air Intake
Helping the Duramax breathe easier is the addition of a premium S&B Cold Air Intake System.
S&B is one of the industry's most respected diesel performance manufacturers, known for producing high-quality intake systems that increase airflow while maintaining excellent filtration.
Benefits include:
Improved throttle response
Increased airflow to the turbocharger
Better engine efficiency
Slight increase in horsepower
Enhanced turbo whistle
Reusable high-flow filter
Cleaner engine bay appearance
It's the perfect performance upgrade while maintaining reliability.
