Is there towing that isn't heavy-duty? Whether it's hauling your boat, bales of hay, or just a trailer, the daily workload we put on our Duramax truck adds stress and strain where we can least afford it: our transmission's flex plate. Improve the longevity of your GM transmission by upgrading to a flex plate that can handle it. The XDP's Tow Series Flex Plate is the heavy-duty part for our heavy-duty lives. It's built from cold rolled steel and a black e-coat finish to help prevent corrosion. XDP's Tow Series was engineered to be ideal for heavy-duty towing, competition, & severe-duty requirements. Upgrade today before a flex plate failure leaves you stranded.
