The Regina 530DR Extra Drag Racing Chain is engineered for the severe demands of drag racing applications. This high-performance chain uses high-alloy steel plates, pins, solid bushings, and rollers to provide dependable operation under extreme acceleration and load conditions. The natural-finish plates identify the 530DR configuration, while the chain’s construction is designed for use in demanding racing environments.
Each chain component is shot-peened to improve fatigue resistance and help maintain durability during repeated high-load cycles. With a breaking strength of 10,566 pounds and a fatigue limit of 2,135 pounds, the Regina 530DR Extra is suitable for applications up to Pro Stock level when properly selected and installed. The 140-link length supports fitment for compatible drag racing motorcycles and drivetrain setups requiring a 530DR chain.
This chain is supplied with a clip- and rivet-type master link for installation flexibility. Verify sprocket compatibility, chain size, required link count, and vehicle-specific fitment before installation. Manufactured by Regina and identified by manufacturer and vendor part number 136DR/1004, this chain is intended for serious racing use where strength, fatigue resistance, and reliable power transfer are essential.
