Specifications
The Kit Masters 4735-41135-66KM Kysair Engine Cooling Fan provides a replacement solution for heavy-duty vehicle cooling systems requiring a 29.5-inch clockwise-rotation fan. Its 2.56-inch center pilot and 3.50-inch mounting bolt circle are important fitment specifications for matching the fan to a compatible drive assembly. Vander Haag's identifies the fan with a 3.00-inch projected width, while Kit Masters' cross-reference catalog associates it with part number 135256-29.5. Horton's equivalent fan specification identifies a nine-blade configuration and additional blade offset measurements, which should be confirmed against the supplied Kit Masters unit. Designed to support radiator airflow and engine cooling, this replacement fan requires careful verification of blade rotation, mounting dimensions, and available clearance.
