Cab & Body Parts
Cab and body parts are ordered by model generation, because cab mounting points moved between the A7, the X3000 and the GTL, and a lock that fits one will not bolt onto another.
This page lists the cab & body parts we supply for Chinese heavy-duty trucks. The group currently covers 78 part numbers, drawn from these sub-categories: Cab tilting (33 items); Cab interior & body (18 items); Protective parts (16 items); Cab body (11 items).
What this category covers
Parts in this group include hydraulic cab lock assemblies and cab tilting mechanisms, cab lift cylinders and lift tubes, cab rotating shafts and bushings, cab suspension shock absorbers and airbag levelling parts, interior trim and headliners, grab handles, exterior protection bars and mudguard components.
Because these items are ordered by number rather than by picture, the list above is not a catalogue of everything we hold — it is the range of part types that sit in this system. The specific numbers in stock move as stock moves, so the reliable way to check an item is to send us the number.
Vehicles covered
The numbers on this page are listed against SINOTRUK HOWO, SHACMAN Delong, FAW Jiefang, FOTON Auman, DONGFENG, CAMC Hualing.
Typical applications are SINOTRUK HOWO (HOWO, HOWO A7, T7H, TX, Steyr, SITRAK); SHACMAN Delong (Delong F2000, F3000, M3000, H3000, X3000, X5000); FAW Jiefang (J5P, J6, J6P, J6L, J6M, JH6, J7, Hanwei); FOTON Auman (Auman ETX, GTL, EST, Aumark); DONGFENG (Tianlong, Tianjin, Kinland, Kingrun, EQ153 chassis); CAMC Hualing (Hualing, Valin, Xingkai, JAC Gallop).
The same system can be built differently across model generations, so two trucks with the same badge may not take the same part. Always confirm against the part number or the chassis number.
How to identify the right part
Before ordering, check these three things: cab type and generation (for example HOWO A7, Delong X3000, Auman GTL), lock orientation and mounting hole spacing, piston stroke length.
If you do not have the part number, send photographs of the old part from two angles and the chassis number. In most cases we can identify the correct number from those alone.

Where a single number covers more than one specification, the variant is listed on the product page, and we will confirm it with you before the order is packed.
How to order
1. Send the part number
Give us the number stamped on the old part, or the number from your parts book. If you only have the chassis number, send that instead — we will look it up.
2. Tell us the vehicle
Tell us the make, model and, where possible, the year of the truck. The same system can use different parts across model generations.
3. Confirm the variant
Where a part number covers more than one specification, we will send you the options with their measurements so you can pick the one that matches your truck.
4. Receive a quotation
We reply with price, packing and shipping options for your destination and quantity. No price is published on this site because freight and quantity change the figure for every order.
5. Approve and ship
Once you approve the quotation we pack the goods, send photographs of the packed cartons, and hand over to your forwarder or ours.
How these parts fail, and when they are replaced
Hydraulic cab locks fail at the seal and at the locking pin. A lock that bleeds down so the cab settles overnight has failed internally, while one that will not release is usually a linkage problem rather than a lock problem.
Cab lift cylinders weep at the rod seal before they lose the ability to hold the cab.
Cab rotating shafts and bushings wear at the bushing, which shows up as a knock when the cab moves on its mounts.
Cab suspension airbag parts fail in the same way as their chassis equivalents, and a cab that sits low on one side usually points at the levelling valve rather than at the airbag itself.
Interior trim and headliners fail by delamination, usually beginning above the doors where the sun load is highest.
Part numbers change between model generations
Part numbers change across model generations even when the visible part looks the same. A housing may be carried over while the connector, the thread or the mounting ear changes, and those are the differences that decide whether a part fits. This is why we ask for the number, and why a part that looks identical to the old one is not accepted as proof that it is the right one.
Packing
Parts in this group are packed according to what they are. Rigid castings travel in cartons with corner protection; pipes and cables travel straight rather than coiled, because coiling sets a bend that is difficult to remove; lamps travel individually wrapped. If the packing needs to suit a particular route or a particular forwarder, tell us when you order and it will be arranged.
Questions buyers ask about this category
How do I know this part will fit my truck?
Check the part number first — it is the most reliable identifier. Then check the vehicle details listed on the product page. If the number on your old part matches, the part fits. If you are unsure, send us the chassis number and a photograph of the old part.
Can I order a single piece, or do I have to buy in bulk?
Both are possible. Consolidating several part numbers into one shipment usually reduces the freight cost per item, so workshop and fleet buyers commonly group their requirements into a single order. Ask us for a quotation on the quantities you actually need.
Is this part made by the truck manufacturer?
No. It is an aftermarket replacement part supplied by SAIWEN, an independent supplier, and it is not made by the truck manufacturer. It is intended to be used in place of the corresponding OEM part.
What information should I send with my enquiry?
The part number, the truck make and model, the quantity, and your destination port or city. A photograph of the old part helps when the number is worn or unreadable.
Can you supply the parts for a whole system rather than individual items?
Yes. Buyers rebuilding a gearbox, a braking circuit or a cab tilting system often order the complete set of related items together. Send the list and we will quote it as one order.
Do you publish prices on the website?
We do not publish prices, because the delivered cost depends on quantity, packing and destination. Send your requirement and we will quote it directly.
Are the part numbers on this site the ones I should search for?
Yes. The numbers shown are the reference numbers used to identify each part. Search by that number, or send it to us, and you will reach the correct item.
Why does the cab lock differ between model years?
Because the mounting point and the locking geometry changed between generations. The A7, the X3000 and the GTL do not share cab lock mountings, so the part number has to match the generation.
Should I replace the lock on both sides?
Not necessarily, but locks are often replaced as a pair on trucks that work daily, because the second is usually at a similar stage of wear.
What if I cannot read the number on the lock?
Send a photograph of the lock in place, including the mounting area, together with the chassis number. Cab lock identification is one case where a photograph resolves most of the uncertainty.
Sending an enquiry that gets a single quotation
A good enquiry takes two minutes to write and saves a fortnight of correspondence. It states the part number, the truck make and model, the quantity, and the destination. Where the number is uncertain it includes a photograph. Where the requirement is a repair rather than a single item, it lists everything intended to be replaced in the same job. Buyers who send the full list in the first message generally receive a single quotation that covers the whole repair, instead of a sequence of quotations that each need a separate freight calculation.
If your number does not match
If the number you send does not match anything in our catalogue, that is not the end of the enquiry. Numbers are frequently superseded, and a number that has been replaced may still identify the correct current reference. Send the old number anyway, together with the vehicle details, and we will tell you what we can and cannot match. We would rather tell you that a number is not available than send a part that will not fit.

Before you send the enquiry
If you are repairing a cab, send a photograph of the mounting area if you can. It removes almost all of the uncertainty around cab lock and tilting parts.
