    These Goodyear Gatorback Poly-V serpentine belts run quieter, stretch less, and transfer more power than other belts do. They can help your harmonic damper to better reduce harmful vibrations by absorbing the shock and vibration transmitted from the crank pulley.  As these belts warm-up, the construction between the cords and rubber compound expands and contracts to become more efficient at turning your engine pulleys and accessories.

    • Quiet Channel Technology: Advanced materials virtually eliminate the usual noise caused by serpentine belt misalignment.
    • Greater Wear Resistance: High strength materials maintain tension integrity during belt service life.
    • Exceptional Belt Life: Advanced materials create a more flexible and cooler running belt, greatly extending the serpentine belt life.

    KRC's idler tensioner is a neccessity on dirt cars because elt slippage can occur on cars that exceed 7,000 RPM. They are also vital if you use a large or heavy fixed fan blade or a fan blade with a lot of pitch. These can potentially causes overheating faster wear. This occurs on both single drive belt and pulley systems with a power steering pump mounted on the front of the engine.

    This happens because the fan belt and pulleys are required to slow the fan. The belt stretches so it slips while braking, inducing heat into the belt. The belt will continue to stretch as the race goes on, causing engine temperature to slowly climb. To properly tension the belt to prevent slippage is with an idler or tensioner pulley mounted on the passenger side of the engine. This helps the engine run cooler and the belt tighter, allowing faster acceleration out of turns & harder braking on corners.
