6-Rib Serp. Belt 37.0in

The 6-Rib Serpentine Belt 37.0in from KRC Power Steering is an OEM-quality replacement belt engineered for reliable accessory drive performance in street and modified vehicles. Serpentine belts are the backbone of your engine's accessory system, routing power from the crankshaft pulley to the alternator, water pump, power steering pump, and air conditioning compressor. At 37 inches long, this belt fits a range of small-block and mid-sized engine platforms, making it essential for builders restoring or upgrading late-model powerplants.

The six-rib design provides superior grip and load distribution compared to older multi-groove belts, allowing higher serpentine tension without stretching or slipping under peak accessory demand. KRC Power Steering, a leader in precision belt and pulley systems, manufactures this belt with EPDM rubber compound that resists heat, ozone, and fluid contamination—critical when running modified cooling systems, aftermarket alternators, or high-output power steering pumps. The consistent rib geometry ensures positive engagement across matched pulleys, reducing vibration and extending belt life even in aggressive driving or track conditions.

Mechanics and engine builders rely on this 6-Rib Serpentine Belt 37.0in when assembling LS-based packages, small-block Chevys, and other modern platforms that demand precise serpentine routing and minimal parasitic drag. Compatibility depends on your specific pulley setup—verify your crankshaft pulley, alternator, water pump, and power steering pump are aligned for a 37-inch belt before ordering. Installation is straightforward: route the belt following your engine's diagram, tension to manufacturer specifications using a belt tension gauge, and recheck after 50 miles of operation to account for initial seating.
