We have created this 68RFE transmission case brace to eliminates cracking that can happen when hauling large loads, towing heavy, and working your Dodge 6.7L Cummins to its full potential. This brace is a creative way to stop the weak transmission casting for flexing, potentially causing a fatal crack that will ruin the transmission, and potentially cost you thousands of dollars due to lost core charges. The ATS 68RFE transmission case brace is a cost-effective solution to protect your truck from future and unneeded repairs.
