Vehicle Configuration
The power comes from a WP7H320E68 diesel engine rated at 320 HP. It is paired with a manual transmission and a MAN 13-ton single-reduction rear axle.
The rear axle ratio is 4.625, giving the tractor useful pulling ability at lower speeds. This can be helpful when starting with a loaded trailer or working on routes with moderate slopes.
Unlike a 6×4 tractor, the 4×2 layout has only one driven rear axle. For normal highway and regional freight work, this can be enough while keeping the chassis relatively simple.
Engine and Transmission



Suspension and Braking
The truck uses leaf-spring suspension with a 3/4 + 3 spring configuration.
Leaf springs remain a common choice for commercial trucks because the structure is relatively simple and local repair shops are generally familiar with them. They can also be useful for customers who regularly operate on mixed road surfaces.
Braking is handled by drum brakes on both the front and rear axles. ABS and ESC are included in the safety configuration.
For a stock or used truck, it is worth checking the brake drums, brake linings, air lines and spring mounting points before shipment.
Tires and Fuel Tank
The tractor is equipped with 11R22.5 18PR tubeless tires.
This tire size is commonly used on heavy commercial vehicles and is suitable for normal road transportation. The 18PR construction provides a heavy-duty tire specification for regular cargo hauling.
A 400L aluminum fuel tank is installed on this version. The aluminum tank helps reduce unnecessary weight compared with a heavier steel tank.
Actual fuel consumption will depend on trailer weight, traffic, road conditions, average speed and driving habits, so the expected driving range should be calculated based on the customer's actual route.
Safety and Driver Assistance
The truck includes ABS and ESC.
It also has LDWS and FCWS. LDWS means Lane Departure Warning System, while FCWS means Forward Collision Warning System. These systems provide additional warnings during driving but do not replace the driver's attention.
A Tianxingjian Zhiyaban BD vehicle-mounted terminal is also included in this configuration for vehicle monitoring and fleet management.
The cab is equipped with electric power windows, while the exterior configuration uses a three-part mudguard arrangement.
Fifth Wheel
The tractor comes with a 50# fifth wheel.
When matching a trailer, buyers should check the fifth-wheel specification, kingpin size, coupling height and trailer weight. These dimensions need to work together to keep the tractor and trailer properly matched.
For general cargo trailers and regional freight transportation, the 4×2 layout can provide a practical balance between vehicle configuration and operating requirements.

Suitable Applications
The SHACMAN M3000L 320HP 4×2 Tractor Truck is mainly aimed at regular road freight.
It can be used with suitable semi-trailers for general cargo, industrial goods, warehouse distribution and regional logistics. The 4×2 chassis is particularly suitable for customers whose routes are mostly paved and whose trailer loads stay within the applicable axle and combination weight limits.
A 4×2 tractor is not intended to replace a 6×4 truck in every situation. If the truck will regularly work on muddy roads, steep terrain or with very heavy trailers, a 6×4 configuration may provide better traction and load distribution.
For ordinary highway and regional transport, however, the simpler 4×2 layout can be a reasonable option.
What to Check Before Purchase
For export orders, the vehicle should be checked against the regulations of the destination country.
Important points include emission requirements, axle-load limits, maximum combination weight, trailer dimensions, fifth-wheel specifications and local tire requirements.
If this is a stock or used vehicle, buyers should also inspect the engine, gearbox, rear axle, brakes, suspension, tires and fuel tank. Checking these parts before shipment can help avoid problems after the truck arrives at its destination.
