Five Nine Fabrication Ram driveshaft loops reduce or prevent damage from driveshaft failures on 2003-2013 Ram 2500/2500 trucks. Hand fabricated in the USA, these loops contain the driveshaft if a u joint failure does occur, hopefully reducing damage to the truck, transmission, transfer case, and other costly parts. These are a great upgrade for peace of mind both on and off road, and something we recommend for daily drivers and off road toys alike.
