Dual Cooler Flywheel Housing Kit

755-8053

Dual Cooler Flywheel Housing Kits - Dual Cooler Flywheel Housing (Bellhousing Only, No Cooler Kits)

This is just one more example of how Keith Eickert Performance Products has taken a proven design and once again improved it even further.  Here are a few of the key features that the Keith Eickert Dual Cooler Flywheel Housings offer.  The traditional water crossover feature that caused so many problems (factory style bellhousings) with delivering enough water to the opposite engine side coolers has been eliminated.  Torsional strengthening ribs have been added for unmatched strength and durability.  This is a common failure point in a factory style bellhousing on high horsepower applications.  Now the water is transferred through a 1-1/4" stainless transfer tube crossover system allowing complete unrestricted water flow to the oil cooler chambers. The improved water flow and cooling features don't stop there, the best part is the convenience of so many plumbing options from the top, bottom or back side for single or dual pass cooling options.  The flywheel housing is cast from 356-T6 aluminum and heat treated prior to CNC machining, next each unit is hardcoat anodized for maximum corrosion resistance. Kits include a dual cooler flywheel housing, oil cooler cover plates, cooler adapter nuts, and stainless steel hardware. Oil plumbing sold separately.

Note: This bellhousing fits Chevrolet engines only. To be used with the Top Mount Starter #620-10060
