Dayco Poly-V Double Sided Stretch Belt — 6PKK1817
The Dayco 6PKK1817 is a double sided Poly-V multi-ribbed stretch belt suited to hydraulic power steering applications on compatible BMW vehicles.
- Double Sided Design: ribbed on both sides, allowing the belt to drive pulleys from either face — used in accessory drive systems where backside pulley contact is required
- Stretch Belt Construction: designed to be installed without a tensioner; the belt maintains its own tension throughout its service life
- Suits Hydraulic Power Steering: confirmed for use in hydraulic P/S drive applications
- Better Belt-to-Pulley Contact: the multiple rib and flat design reduces slippage and improves power transmission efficiency
- Flexural Stress Relief: grooved design provides flexibility in both normal and backside bending, reducing stress fatigue and improving durability
- Resistant to Environmental Factors: grooved profile makes the belt less susceptible to dust and splash-induced slip
- Controlled Slippage in Overload: multiple ribs eliminate the need for matching and allow for controlled slippage in overload situations, protecting driven components
- Rubber Impregnated Fabric Backing: maximises load carrying capability across the belt's service life
- Stabilised Cord Treatment: cord is saturated with a specially formulated treatment that ensures length and belt stability for the life of the belt
- Reading the Part Number: the number before PK is the rib count and the number after it is the belt length in millimetres — 6PKK1817 is a 6-rib double sided belt, 1817mm long
Check the part number, rib count, length and belt type (double sided/stretch) against your application before ordering.
Please check the belt fitted to your vehicle before ordering. Some engines use a single belt to drive multiple components, while others use separate belts for the Main/Drive, Air Conditioning (A/C) and Power Steering (PS) — in various combinations depending on the engine and options fitted. Where possible we specify which position a belt suits, but due to the complex and often incomplete nature of catalogue data, this isn't always able to be listed. If you're unsure which belt(s) your vehicle needs, please contact us before ordering, or check the belt currently fitted to your engine.

Fitment (vehicle-specific products): For products listed to suit a specific vehicle, our fitment data is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing. If you have any doubt, please message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm before you buy.
