RK 530 ProDR chain is the ultimate drag racing chain.  It is a non-sealed chain and has the highest tensile strength of 52.3kN and is suited specifically to drag racing.

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.

RK’s Pro DR Drag Racing Chain weighs less than most 530 Sealed chains. 530PRODR is designed to replace other Heavy Duty 630 & 530 chains
