Product Details

The Sierra 18-15400 is a heavy-duty V-belt engineered for demanding marine engine applications. This precision-manufactured belt delivers reliable power transmission for alternators, water pumps, and other belt-driven components on inboard and stern drive engines.

Key Features:

  • High-strength synthetic cords resist shock load failure and sudden stress
  • Special rubber compound compression section ensures smooth, even load force transfer to the cords
  • Precision-molded cogs engineered to exact tolerances for improved flexibility while maintaining cord support
  • Advanced cog geometry creates large air circulation areas to keep the belt cool and prevent heat buildup in the cushion section
  • Rubber edges maintain positive, no-slip contact with pulley grooves for consistent performance

Sierra marine belts are manufactured to meet or exceed OEM specifications, providing dependable performance in harsh saltwater and freshwater environments. This replacement belt helps maintain proper engine operation and charging system function.

Product got here quickly in great shape! Autoplicity does things right!

fast and easy with great pricing. short bed liner and dark window vents at one stop shopping.

simple

I was very impressed by Autoplicity's customer service and excellent pricing on brand name products. Also, they provided lightning fast shipping even as the holiday weekend approached.<br>As much as I want to see everyone in this world to "live long and prosper," I was especially pleased to deal with a company that did not export their customer service to another country. <br>I look forward to doing business again with Autoplicity.

Just order the 1108 turn over ball for 2010 Super Duty and received it within (5) days. Just can't wait to put it on and start pulling the trailer with my new diessel.

hope shipping is fast

Easy and fast, can't beat that with a stick. It even arrived a day earlier than indicated. What else can I ask for. The install was really smooth and really did only take me about an hour. However, I did have access to a lift because a friend of mine owns

Found what I wanted at the best price on the internet! Good tie-in with Amazon also.

no place to put discount shipping code

Very good experiance with seller. I order husky floor liners for my '09 honda accord and they where 30-40% less than any other online store. Item arrive quickly, And couldn't be more happier with transaction. Defenetly i will look forward for my next car needs to deal with Autoplicity. 5 Star defenetly...............
