Polyforce Belt Tensioner
#KMR689448
Product Overview
PolyForce Belt Tensioners by Kit Masters replace the traditional spring with a longer-lasting, Polymer Torsion Core. They also feature upgraded pulley bearings to drastically extend the life of the belt tensioner.
Features & Benefits
- No Springs Attached - Conventional belt tensioners use springs to hold their position and tension. However, springs can only flex so many times before they fail. PolyForce™ Belt Tensioners replace this spring with a longer lasting, new and unique Polymer Torsion Core. A compressed silicone replaces the spring, thereby eliminating the primary cause of failure.
- Improved Bearings - The other common failure point in a belt tensioner is the bearing. The pulley bearing absorbs a huge amount of vibration and can often fail too soon. PolyForce™ Belt Tensioners have dramatically improved pulley bearings to give them extended life. Our bearing is designed specifically for pulley applications with Outer Ring Rotation and Anti-Vibration Grease (won’t separate).
- No Spring = Less Heat - To demonstrate the difference between tensioners, we ran a PolyForce belt tensioner and a competitor’s belt tensioner along an oblong pulley, which causes it to flex back and forth. After 20 minutes the competitor’s belt tensioner was 62.5% hotter than the PolyForce belt tensioner. Less heat leads directly to longer lasting components and assists in achieving lower under-hood temperatures.
