RK Racing Chain Master Chain Tool Set
Professional Chain Tool — Precision Power for Serious Wrenching
Built for riders and mechanics who don’t mess around, this heavy-duty chain tool makes quick work of 40 and 50 series chains with accuracy you can trust. From breaking chains to press-fitting side plates and flaring rivet pins, it delivers clean, controlled results every time.
Designed to handle tight-tolerance O-ring chains, the press-fit system seats side plates to the correct depth for both clip and rivet-style master links. A redesigned body locks components securely in place, while the larger pressure bolt gives you more leverage and smoother operation — no dropped parts, no frustration.
Smart updates make this tool easier and safer to use: a redesigned sure-grip handle, laser-engraved part numbers for fast identification, and a reversible plate holder that switches between clip and rivet plates in seconds. The upgraded rivet flare pin now includes a built-in guard to prevent over-flaring, protecting both the chain and your work.
Backed by a limited lifetime warranty on the tool body, this is a workshop essential built to last through countless chain jobs.
⚠️ Note: Press-fitting 40-series chains requires part #PH428 (sold separately).
