Did you know Super Late Model fan belts slip twice on every lap? Save money by eliminating the tensioner while improving performance. Why settle for 5 ribs when the KRC System gives you 10?
Examine your current pulley system. If the coating has vanished you are likely experiencing chronic belt slippage.
Engine deceleration causes the fan rotation to drop nearly instantly from around 7800 to 3500 rpm. Sudden deceleration occurs twice a lap resulting in belt slippage and premature wear.
KRC resolved the problem with a unique 10-Rib Belt System constructed with Kevlar cords that offers 100% more surface contact than previously available.
Driving the fan has not been the problem, says KRC President Ken Roper, slowing it down in an instant is the cause of belt slippage and pulley wear. Deceleration forces are usually more than a five- or six-rib serpentine belt system can control.
After running 1500 hard dirt track laps on this kit, we displayed our 10-Rib system at the PRI Show. The pulleys looked so good we could "show" them. Virtually zero wear and the belt grooves looked nearly new even after 1500 laps which is 6000 decels & accelerations.
