Why VNX?

Reasons to love the vnx

From end-to-end, every feature of the VNX is built to stand up to any heavy-haul job you throw at it.
Improvements are easy to see throughout the VNX including the bumper, axles, suspensions, braking,
powertrain, and more. Every detail has been examined to increase durability and ensure you’ve got the
tools you need to move extreme loads.

Wide Tires

Tires bear a huge burden in heavy-haul applications. The VNX is engineered to handle rugged tires that must stand up to extreme loads on punishing roads and construction jobsites. The VNX can accommodate front axle tire sizes up to 445 mm.

Durable Framerails

VNX framerails (side members) are constructed of 760 MPA heat-treated alloy steel with a yield strength of 120,000 psi. Several combinations of frame rail height, thickness, and liners are available to meet a wide variety of hauling requirements.

Fifth Wheel

Fifth wheels on the VNX feature a load capacity of 55,000 lbs. or greater and pull capacity of 150,000 lbs. or greater, ideal for trailer applications from low-boys to b-trains and long combination vehicles.

Powertrain

Performance and profitability meet

Heavy hauls require brute force and sharp wits. You’ll need power to get the load moving and fuel efficiency to make a profit doing it. At Volvo, fuel efficiency is a vital part of our commitment to your business and the planet we all share. We believe that fuel efficiency is more than a single feature; it’s a combination of customized solutions working together in perfect harmony. The result is fuel efficiency custom-built to help you cut operating costs whatever the load.

MAKE THE SHIFT TO LOW-SPEED STARTABILITY

I-Shift

Our newest I-Shift makes every load more productive, using intelligent electronics to continuously monitor grade, speed, weight, and engine load, shifting when necessary or holding a gear—whichever saves more fuel. So regardless of experience, training, or application, I-Shift helps every driver become more fuel efficient.

I-Shift with Crawler Gears

I-Shift with Crawler Gears has a 1,900 lb-ft. torque rating. It includes upgraded hardware and software including a new countershaft brake for improved performance and smoother shifting. And the electronic control unit can handle any load and any road, shifting perfectly every time.

Transmission Cooler

I-Shift’s transmission cooler optimizes fluid temperature in cold and warm climates, improving fuel efficiency even on heavy-haul loads. Connections throughout the transmission are also upgraded for faster maintenance stops.
