The 6PK1803 belt is a 6-rib automotive poly V belt with a nominal length of 1803 mm. It is also listed in aftermarket catalogs as a serpentine belt, V-ribbed belt, multi-rib belt, or auxiliary drive belt.
For automotive parts distributors, wholesalers, repair businesses, and aftermarket importers, the 6PK1803 reference provides a more precise way to identify the required belt than searching only for a general term such as “automotive belt.”
When sourcing a 6PK1803 supplier, buyers should confirm the rib number, belt length, material, application, reference numbers, packaging, and required quantity before placing an order.
The basic meaning of 6PK1803 can be understood from its designation:
Specification | Reference |
|---|---|
Belt type | Poly V / V-ribbed belt |
Rib count | 6 ribs |
Nominal length | 1803 mm |
Application | Automotive accessory drive |
Common description | 6PK1803 serpentine belt |
Product category | Automotive drive belt |
Aftermarket catalogs identify 6PK1803 products as 6-rib belts with a length of approximately 1803 mm. Some listings also provide a width of approximately 21 mm, although the exact product construction and dimensional tolerance should be confirmed against the manufacturer's specification.
The 6PK designation therefore provides information about the rib configuration, while 1803 identifies the nominal belt length in millimeters.
The designation 6PK1803 contains two main pieces of information.
The 6PK portion indicates a multi-rib belt with six longitudinal ribs.
A 6PK belt is designed to engage with a compatible multi-rib pulley system used in an accessory drive.
The 1803 portion refers to the nominal belt length of approximately 1803 mm.
This combination makes 6PK1803 much more specific than simply searching for:
6PK belt
or
automotive serpentine belt
For aftermarket purchasing, the complete product reference is usually a more useful starting point.
Not every 6PK belt has the same length.
For example:
Belt Reference | Rib Count | Nominal Length |
|---|---|---|
6PK1803 | 6 | 1803 mm |
6PK1800 | 6 | 1800 mm |
6PK1805 | 6 | 1805 mm |
Aftermarket catalogs show that 6PK1803 can have cross-reference relationships with nearby 6PK references such as 6PK1800 and 6PK1805. However, this does not mean that the products should automatically be treated as interchangeable. The actual vehicle, pulley system, tensioner range, belt construction, and manufacturer reference should be checked before substitution.
This distinction is particularly important for distributors purchasing belts in bulk.
The 6PK1803 serpentine belt belongs to the multi-rib accessory drive belt category.
Depending on the specific product reference, 6PK1803 is listed in aftermarket catalogs for applications associated with brands and vehicles including Ford, Opel, Renault, Saab, Chrysler, Jeep, Volvo and other applications. The exact application should always be confirmed using the applicable reference number and vehicle or engine information.
A buyer should therefore avoid treating 6PK1803 as a universal fit for every vehicle using a six-rib belt.
The product reference identifies the belt configuration, while the application information helps confirm whether it is suitable for a particular vehicle.
When purchasing a 6PK1803 replacement belt, checking the original belt reference is the first step.
Additional information can include:
Number of ribs
Belt length
Belt width
Belt material
Tensile cord material
Vehicle model
Engine model
Existing belt number
OE/reference number
Product photo
For example, aftermarket listings for 6PK1803 products commonly specify 6 ribs and approximately 1803 mm length, while individual manufacturers may list additional information such as EPDM rubber, polyester tensile cord, and belt width.
This information is useful when comparing products from different suppliers.
Generic searches such as automotive belt supplier can return a very broad range of products.
A search for 6PK1803 belt supplier, however, already indicates that the buyer has a specific belt configuration in mind.
This type of product-specific search can help buyers:
Find a specific belt model
Compare aftermarket suppliers
Request wholesale pricing
Check product availability
Compare alternative references
Confirm application information
Source private-label products
For an automotive parts importer or distributor, a specific reference number can also make communication with a manufacturer more efficient.
A reliable 6PK1803 supplier should be able to provide clear product information rather than only a product name.
Useful technical information includes:
The supplier should identify the nominal belt length and rib configuration.
For 6PK1803, the basic reference indicates six ribs and approximately 1803 mm nominal length.
Different aftermarket belt products may use different rubber formulations and reinforcement structures.
EPDM is commonly specified for modern automotive serpentine belts, and some 6PK1803 aftermarket products list EPDM rubber as the belt material.
The tensile cord contributes to the belt's dimensional stability and tensile strength.
Product specifications may identify polyester or another reinforcement material.
A supplier should provide available application or cross-reference information when applicable.
This is particularly useful when a distributor needs to match one belt reference to multiple vehicle applications.
A 6PK1803 cross reference can be useful when an importer or distributor is looking for alternative aftermarket sources.
Online aftermarket catalogs currently show 6PK1803 associated with multiple manufacturers and reference numbers. For example, listings include Gates, FLENNOR, FAI AutoParts, INA and other aftermarket products using 6PK1803 or related references.
However, cross-reference information should be treated as a product identification aid rather than an automatic replacement approval.
Before placing an order, confirm:
Rib count
Length
Width
Material
Application
Original reference
Manufacturer specification
This is especially important when nearby references such as 6PK1800, 6PK1803, and 6PK1805 appear in the same aftermarket catalog.
For wholesalers, the requirements are usually different from those of an individual replacement buyer.
A wholesale buyer may need:
Multiple cartons
Stable repeat supply
Customized packaging
Private-label packaging
Product labeling
Mixed belt references
Consistent specifications
Export documentation
Long-term supply arrangements
Instead of asking only:
“Do you have 6PK1803?”
a distributor can provide a complete purchasing requirement:
Product: 6PK1803 belt
Quantity: Required order quantity
Application: Automotive aftermarket
Packaging: Standard or private label
Target market: Country or region
Additional references: Other 6PK models required
This allows a manufacturer or supplier to evaluate the complete order rather than a single product.
When sourcing a specific belt reference, buyers may encounter both manufacturers and trading companies.
A 6PK1803 manufacturer generally focuses on production capability, product specifications, quality control, packaging, and customization.
A trading supplier may instead consolidate products from several manufacturers.
Neither business model should be judged only by the company description. Buyers should verify the information that matters to their purchasing requirements.
Useful questions include:
Is 6PK1803 currently available?
What is the material?
What is the exact belt width?
What are the reinforcement specifications?
What applications are supported?
Can samples be provided?
What is the MOQ?
Can packaging be customized?
Can other PK belt references be supplied?
What is the normal production lead time?
A precise RFQ can save time when contacting an aftermarket belt supplier.
A simple inquiry can include:
Product: 6PK1803 automotive poly V belt
Required quantity: ______ pcs
Application: Automotive aftermarket
Packaging: Standard / private label
Target market: ______
Additional belt references: ______
Sample requirement: Yes / No
If the buyer has the original belt, a product photo and original reference number can also be provided.
For larger orders, buyers can request technical specifications, packaging information, sample confirmation, and quotation together.
For buyers sourcing automotive aftermarket belts from China, the supplier should be evaluated according to the actual product requirements rather than the country of origin alone.
Important factors include:
Manufacturing capability
Product range
Quality management
Belt specification control
Custom packaging
Production capacity
Export experience
Aftermarket product coverage

3PK → 4PK → 5PK → 6PK → 7PK → 8PK → 10PK → 12PK → other configurations
Length
Each rib configuration can contain multiple belt lengths.
Application
Automotive → commercial vehicle → truck → other accessory drive systems
Material
EPDM and other available belt constructions according to the application.
This structure allows distributors to build a more complete aftermarket belt catalog instead of relying on a single popular reference.
Before confirming an order, check:
Product reference: 6PK1803
Six-rib configuration
Nominal length: 1803 mm
Belt width
Belt material
Reinforcement cord
Application
OE/reference numbers
Product packaging

Sample requirements
Private-label requirements
Shipping destination
For replacement applications, the original belt number and vehicle/engine information should also be checked.
A 6PK1803 is a six-rib automotive poly V or serpentine belt with a nominal length of approximately 1803 mm.
The 6PK identifies the six-rib PK configuration, while 1803 refers to the nominal belt length in millimeters.
They are different reference numbers. Aftermarket catalogs may show related or cross-reference applications, but buyers should confirm the exact application and belt specifications before substitution.
Material can vary by manufacturer and product line. Several aftermarket 6PK1803 listings specify EPDM rubber, while reinforcement may include polyester cord. The exact material specification should be confirmed with the supplier.
Automotive aftermarket manufacturers, distributors, and parts suppliers may offer 6PK1803 belts. For wholesale sourcing, provide the required quantity, application, packaging requirements, and complete product reference to the supplier.
This depends on the manufacturer's production and packaging capabilities. Wholesale buyers should confirm MOQ, packaging format, labeling requirements, and artwork specifications directly with the supplier.
Search using the complete product reference together with procurement terms such as 6PK1803 supplier, 6PK1803 manufacturer, 6PK1803 wholesale, or 6PK1803 factory. For a quotation, provide the exact reference and required quantity.
The 6PK1803 belt is a highly specific automotive poly V belt reference, identifying a six-rib configuration with a nominal length of approximately 1803 mm.
For aftermarket buyers, using the complete reference number makes product sourcing more precise than searching for a general automotive belt.
When looking for a 6PK1803 supplier, buyers should compare not only price, but also belt dimensions, material, reinforcement, application coverage, cross-reference information, packaging, and supply capability.
For distributors and wholesalers, the same product reference can also be used as part of a broader PK belt purchasing program covering different rib configurations and belt lengths.
