Description

The Wehrli Custom Fab WCF100130 Transfer Case Brace is designed to eliminate driveline flex and reduce the risk of a cracked transmission tail housing. This brace installs easily using factory fasteners, spreading the load across the transmission center section without requiring the removal of the transmission or transfer case.

It adds significant strength and reduces driveline flex, especially in extreme applications like pulling, drag racing, and off-road use. The brace is compatible with 2001-2007 GM 6.6L Duramax LB7/LLY/LBZ engines.
