BUILT FOR THE CHALLENGE
The heavy-duty vocational frame underneath the 49X is engineered to stand up to the demands of severe service applications like construction,
logging and heavy haul trucking while being lighter weight, more durable, easier to service and extremely Truck Equipment Manufacturer (TEM) friendly.
The industry's first high-strength single-channel rail gets you 3.7 million RBM without an insert. All the strength you need without the weight and risk of corrosion.
SPLAYED FRAME RAILS
Splayed frame shape at the front of the chassis allows for lower engine and radiator packaging that optimizes hood slope for increased visibility and safety, as well as improved engine serviceability.
FULL PARENT FRONT FRAME RAIL EXTENSION OPTIONS
Multiple parent rail front frame extension options are available, eliminating the need for bolt-on extensions or reinforcements.
Straight frame sections begin directly behind the cab and feature a constant flange-to-flange dimension, making upfit easier.
All midship and suspension crossmembers are bolted, not welded, for greater durability and easier maintenance.
Phosphate-coated Class 10.9 fine-thread fasteners offer a high clamp load and don't require maintenance.
FRONT TOW ASSEMBLY
A number of towing device options mounted directly to the front frame head for incredible strength, allowing you to pull your truck free without damage.
ROBUST ROUTING AND CLIPPING
Frame rail stand-offs keep wiring and air lines separated and away from the chassis to reduce corrosion, debris damage and diagnosis time.
POWER TAKE OFFS
From snowplows and mixers to bulk haul tractors and everything in between, the wide selection of options on the 49X lets you choose the right
combination of front engine PTOs (FEPTO) and transmission-mounted PTOs so you can install the equipment you need for your application.
PURPOSE BUILT OPTIONS
We spent half a decade designing and engineering the all-new 49X to be the best vocational truck on the market. Period. To
achieve that, the 49X had to meet seven benchmarks we established at the start of the project. And we put it to the test to make
sure it delivered on every one of them.
The 49X offers three bumper styles in various finishes and thicknesses, as well as a boxed-in bumper with an optional grille guard for logging applications.
FRONT TOW DEVICES
A number of towing device options mounted directly to the front frame head of the 49X for increased strength and durability with up to 140,000 lb tow capacity.
Durable, lightweight aluminum tool boxes are available in 18-, 24-, and 34-inch widths. All are locking and can be ordered with plain, polished or diamond plate finish covers.
Battery boxes in the 49X can be mounted between rails, inside the cab or on the frame. The frame-mounted boxes are also made from lightweight, corrosion-resistant aluminum for long life.
Optional left-side access hatch available for easy check of key fluid levels without opening the hood or removing front-mounted equipment.
AIR CLEANER OPTIONS
The optional pre-cleaner removes 80% of the particles out of the air before entering the primary air cleaner, extending filter life and service intervals in off-road environments.
