I was looking for a replacement belt for my lawn mower.

The manufacturer (Sears) has one listed that has Kevlar in it. Has anyone used a drive belt in a car or anywhere else with Kevlar? Does the Kevlar make for an improvement in performance or longevity? Iirc the factory belt has been in service for about 10 years or so but needs to be replaced.


Here is their comment:

...made with Kevlar replacement belt costing less than the OEM. Belt is made to FSP specs, 1/2 X 88.375" (2244.725 mm). For the 144200, Same as Husqvarna belt 532144200. Used on many 42" vented decks, 1994 to about 2000. Kevlar corded lawn and garden belts have become increasingly popular over the last few years due to their extreme strength, durability, and value-added pricing. Kevlar corded belts, also called Aramid or extra-heavy duty belts are constructed of organic polyaramide fibers that are manufactured using complex chemical processes. **Interesting fact: Kevlar is the same material bulletproof vests are constructed with. Kevlar is used in PIX belts as a tension member because of its inherent stability and high tensile strength Cord
