Did you know Super Late Model fan belts slip twice on every lap? (-25% Reduction Kit)To prove or disprove it, simply examine the coating on the water pump and crank pulleys. If the coating on the working surfaces has vanished, the belt is slipping—probably chronically. Most Super Late Models, in common with IMCA Modifieds, encounter belt slippage every lap as the engine instantly decelerates on each straightaway, resulting in fan deceleration from around 7,800 to 3,500rpm—a tumultuous event that erupts over a second or two. KRC resolved the problem with a unique 10-rib belt constructed with Kevlar cords that offers 100% more surface contact than previously available. “Driving the fan has not been the problem,” says KRC’s Ken Roper, “slowing it down in an instant is the cause of belt slippage and belt stretch. The deceleration forces are usually more than a five- or six-rib serpentine belt system can control.” Belt slippage and belt stretch are the most prominent causes of belt replacement.

• Greater belt strength using Kevlar cords and elimination of cross-cut Gatorback design

• 100% greater surface contact between belt and pulleys

• Hard anodized water pump pulley, crank pulley and crank hub

• Assembly hardware and detailed installation instructions included

• Available for IMCA Dirt Modified with integrated dual pump system (power steering & fuel).

Products typically ship out between the same day and 1-3 days. Depending on the time/day ordered and the product type. Some products are made to order to spec and will ship once built. Feel free to call us at 704-871-0721 if you have any questions about shipping. Also call us if you are ordering large items like race car bodies as those are hard for the freight system to calculate sometimes and it will overestimate. Thank you.
