Local NASCAR driver Norm Weaver brings his truck differential to CMR Rebuild. The number 11 truck has a special differential where you remove the third member from the front of the differential case then rebuild on the bench. Mr. Weaver has spare third members that CMR sets up for a quick change during a race. Mr. Weaver has been a customer since 2005. CMR Rebuild is please to support Mr. Weaver on his endeavors to win in the NASCAR Truck Series races.
