530PRODR is one of RK Chain's new additions and is the ultimate in drag racing chain. 530PRODR non-sealed drag chains have the highest tensile strength available for drag racing at 11,880 lbs. Drag racing chains must be able to withstand the extreme load of drag racing at the start of each race. The quick buildup of speed generates a lot of heat, which can transfer into heat friction. RK Chain's 530PRODR components are reinforced with a heat-resistant treatment to reduce heat friction and maintaining efficient horsepower delivery.
