THE X-SERIES CAB
MAKING LEGENDARY PERFORMANCE LIGHTER AND SAFER
Constructed from an aerospace-grade aluminum and enhanced with steel reinforcements, the new X-Series cab is light, safe,
strong and spacious so that it can help protect and retain operators while delivering greater payload and uptime for a variety
of demanding applications including dump trucks, cement mixers, log trucks and heavy haul.
Composite roof with a lowered center section enables optimized packaging of overcab equipment, minimizing overall
vehicle height, while maximizing interior headroom and door openings.
Our engineers used state-of-the-art technology to place structural material and reinforcements strategically
to minimize weight while maximizing toughness and safety.
- Backwall Header Reinforcement
- Increased A-Pillar Section Size and Strength
- B-Pillar Reinforcement
- Hinge Reinforcements
Quiet Steel®* engine tunnel reduces engine noise intrusion into the cab to provide a premium operating environment.

VOCATIONAL TUNED CAB MOUNT SYSTEM
The X-Series cab mount system features vocationally tuned cab isolators designed to reduce operator fatigue by
providing optimal cab stability, helping deliver the incredibly comfortable ride Western Star is known for.
THE X-SERIES DOOR
The X-Series door is designed as an integral part of the steel-reinforced aluminum cab structure. Built from
rugged steel and designed to be easy to service, it will deliver greater uptime and operator comfort for years to come.
C-BAR MIRROR SYSTEM
We designed our new mirrors to deliver what your operators need and more, with features that enhance visibility, reduce operator
fatigue, improve safety and increase uptime. You'll never look at a mirror the same way again.
Reduced profile for greater forward visibility and reduced resistance.
Optimized and stiffened to avoid low-frequency and low-engine speed vibrations.
Optional heating system keeps mirrors free from frost and snow.
INTEGRATED TURN SIGNALS
Easy-to-see integrated signals offer added safety for operators and other motorists.
INGRESS AND EGRESS
Getting in and out of the cab is a big part of any vocational operator's day. To make it easier and safer,
the 49X offers a number of features and improvements.
Expansive door opening area with wide 70-degree opening angle to ease ingress and egress for the largest operators.
Re-engineered locations for safer and more comfortable entry and exit.
Made from corrosion-resistant aluminum with lower step-in height and improved volcano tread for safety.
Defines the entry and makes the cab easy to sweep out.
STRONGER. LIGHTER. BETTER. THAN EVER.
Engineered to improve durability and performance, as well as provide the best operator visibility possible. The new
molded resin hood is nearly 100 pounds lighter than our previous hood, and is designed to resist high impacts to
last the life of the vehicle. Strength and durability while reducing weight so your operation can haul more and make more.
ISO TECH HOOD SUSPENSION SYSTEM
Our all-new exclusive ISO Tech Hood Suspension System absorbs shocks and isolates the hood from brutal
road conditions to reduce the chance of cracking and costly hood replacements.
ALL METAL BRIGHTWORK
Features including the intake cover, grille, sun visor and more, and are built from durable, long-lasting metal.
Dual stainless steel air intakes are fashionable and functional, feeding our new, easy-breathing underhood air cleaner.
Mounted directly to the radiator for easy hood opening with bumper-mounted implements, the grille is made from a single
piece of stainless steel with external stainless fasteners for easy replacement.
A 72-degree service opening for easy servicing of underhood components. Standard hood strut lock keeps the hood from closing in windy conditions.
Made from steel-reinforced molded resin material designed to take a hit, and featuring new flares that protect the hood, cab and frame sides from splash and debris.
RADIATOR AND COOLING
Choose from our standard serviceable aluminum radiator that delivers excellent performance and reduced maintenance costs, or our optional severe service radiator for demanding applications.
Features self-locating rubber cowl hood mounts to secure the hood and constrain it from lateral movement while remaining easily accessed with a single gloved hand.
Our underhood air cleaner offers nearly the same dust capacity as twin external canister air cleaners with 60 percent less weight and half the replacement time.
Structural provisions for auxiliary mirrors eliminate the need for additional hood reinforcements, reducing cost, time and complexity of retrofitting.
