Product Details

The Gates 39148 Belt Tensioner Assembly is a premium OE-quality automatic belt tensioner designed to maintain proper serpentine belt tension throughout the life of your drive system. This tensioner uses a self-adjusting spring mechanism to compensate for belt stretch and wear, ensuring consistent tension and preventing belt slippage that can lead to accessory failure.

Key Features:

  • OE-equivalent design for direct fit replacement
  • Automatic tensioning mechanism maintains optimal belt tension
  • Pre-lubricated bearing assembly for smooth operation and extended service life
  • Heat-treated steel construction for durability in high-temperature engine environments
  • Includes mounting hardware for complete installation
  • Precision-engineered to meet or exceed OEM specifications

Gates is a trusted leader in automotive belt drive systems, and this tensioner delivers the quality and reliability professionals expect. Regular replacement of worn tensioners helps prevent unexpected belt failure and protects expensive engine accessories like alternators, power steering pumps, and air conditioning compressors.

Good but would like to have a link to the manufacture.

Great

thanks for having such great prices

Easy to order. Good prices on shipping.

Very easy system!! Thanks!!

Amazingly cheap prices for what i was looking for, best online and pretty fast shipping. Took awhile for my order to be confirmed though, not sure why. But still impressed with the price set.

great

Quick and painless

Really impressed with prices! Took two weeks to get everything but worth for money I have saved.

With money being tight, we have to do whatever we can to save a few dollars here and there. Autoplicity ended up having the absolute lowest shipped price on the item I needed, and it arrived sooner than I had anticipated! There is not much else they sell that I would need, but for others who need Magnaflow exhaust parts, I am recommending they check Autoplicity for a good price.

Easy deal

This store had a lot of products more than most other sites I looked at. The order was processed quickley and shiped the next day. I will use them again.

A+++++<br>Order was placed on a sunday.<br>It was sitting on my doorstep wednesday morning! <br>Would recommend to anyone.<br>Great Prices!
