Product Details

The Caliso 850K7 is a heavy-duty Poly V serpentine belt engineered for reliable power transmission in automotive and light-duty applications. Built to K-section (PK) ribbed belt standards, this 7-rib belt delivers smooth, efficient transfer of power from the crankshaft to engine accessories including alternators, power steering pumps, air conditioning compressors, and water pumps.

Key Features:

  • Section Type: K-section (PK profile) Poly V ribbed belt
  • Effective Length: 850mm
  • Number of Ribs: 7 ribs for maximum surface contact and load distribution
  • Rib Pitch: 3.56mm standard K-section spacing
  • Constructed from high-strength rubber compound with internal tension cords for dimensional stability
  • Resists heat, oil, and abrasion for extended service life
  • Designed to OEM profile standards for accurate fit on K-section pulley systems
  • Low-noise operation with flexible, fatigue-resistant construction

The 850K7 is a direct replacement for worn or cracked serpentine belts on vehicles and equipment using 7-rib K-section drive systems. Always inspect belt tensioners and pulleys during replacement to ensure optimal belt life.

Super fast ship and best price!

Excellent service

Good quality product, fair price, and delivered without any delays.

The shopping was easy. I was able to look up the specs easily.

The order itself was great, exactly what I needed for a great price. The shipping however was dismal. I had paid for 2 day shipping but received it after 7 days. After contacting customer service, the issue was resolved quickly and money refunded for the shipping charge. Great CS and place to shop.

It was fast and easy to order the things I needed.

The web sit was very easy to navigate and I was able to find the fuel pump for my vehicle that no one else seemed to carry and for a reasonable price all I can say is thank you so very much!!!

Fast service and top of the line products. Easy to order online and they follow up to make sure you are pleased with the product you had ordered.

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.
