The Belt Tensioner's structure commonly comes with a pulley, tensioner arm, a spring, and a base; many Jeeps employ an automatic belt tensioner that changes tension actively to increase efficacy.

The Belt Tensioner is unique in the automotive market because of its highly constructiveness and its vital function to guarantee smooth power transmission thus making it a favorite among Jeep lovers. Both the performance and security aspects are significant to the Belt Tensioner; therefore, it forms a credibility aspect of the Jeep category of automobiles.
