What This C7 Tractor Offers
The SITRAK C7 4X2 is a long-haul tractor unit: a China VI diesel up front, a manual gearbox in the middle and an air-suspended rear axle under the fifth wheel. It is the kind of tractor truck for sale that suits operators pulling a fixed trailer over long distances, where coupling height has to stay put when the load shifts.
China VI Weichai Diesel
The WP11.460E61 is a six-cylinder water-cooled diesel built to China VI. SITRAK fits it as standard to the C7, so filters, injectors and service knowledge are already in place along the routes this unit is likely to run.
Manual Gearbox
Drive goes through an HW25716XSL manual transmission. There is no automated clutch to diagnose far from a dealer, and a driver who knows the box can hold a gear on a long climb instead of letting it hunt between ratios.
Air Suspension On The Rear Axle
The rear axle is an MCY13 single-reduction unit carried on air bags, with a few-leaf spring at the front. Ride height stays where it was set whether the trailer is empty or loaded, which is what protects the fifth wheel and the coupling plate.
TGA-B Frame And 50# Fifth Wheel
The chassis is built on a TGA-B frame with a 50# fifth wheel and a Bosch 8098 steering gear. That is the combination that keeps a loaded trailer tracking straight at speed and makes the unit easy to place under a parked trailer.
How These Photographs Were Taken
Every unit is photographed on our own yard before it goes into the listing, and the frames below come from that set. They were shot in daylight on the same morning, with the cab and chassis clean and nothing moved for the camera. What is shown here is the exact tractor truck for sale in this listing, not a stock picture of the model.

Which Duty Cycle Fits
A 4X2 tractor is only as good as the work it is given, and most buyers looking at a tractor truck for sale at this size are moving one of the four loads below. Name the one that matches your operation and we will confirm what the unit needs before you commit.
Trailer work between cities on trunk routes
Continuous running where fuel burn is the main cost
Gradients and long climbs with a loaded trailer
Drivers who want a manual box they can hold in gear
Depots that already stock Weichai filters and oil
Moving containers between a port and an inland yard
Repeated short runs with a fixed skeletal trailer
Tight stacking areas where a short unit turns easier
Long waits at the gate with the trailer coupled
Fixed ride height while a box is loaded and pinned
Deliveries within a day's drive of the depot
Mixed weights, from part loads to a full trailer
Depots with no pit, so servicing happens at a dealer
Routes with toll gates and tight roundabouts
A 4X2 keeps purchase and tyre cost down
Liquid and powder tankers with a fixed pin position
Loads that shift, where ride height must not change
Long runs carrying a heavy, constant load
Air suspension takes the shock out of a full tank
A manual gearbox holds a steady speed on a climb
Specification As Built
The figures below are taken from the unit's own build sheet. Axle ratio, tyre brand and any trailer-specific fittings are not fixed at the factory, so tell us the work you have in mind and we will confirm those against your application.

before the unit is released
Photographs tell you what a tractor looks like; they do not tell you whether the air holds or the gearbox is quiet. Nothing is released until the same routine has been run on the unit standing in front of us. The diesel is started and brought up to temperature, the air system is pumped up and left to stand, and every gear is selected and released with no trailer on the fifth wheel.
Documents follow the same route. The build sheet is checked line by line against the chassis number, so nothing is assumed later. Freight is quoted against the port you name rather than a default one. Invoice, packing list, bill of lading and any certificate you need are prepared together as a single set, and the report we send back is written as found.
