DRAG SPECIALTIES Socket-Head Camshaft Primary Transmission Bolt Kit MK197

A complete motor rebuild demands fastener integrity across every critical junction—and OEM hardware often leaves performance builders sourcing from multiple suppliers. The Drag Specialties Socket-Head Camshaft Primary Transmission Bolt Kit MK197 consolidates all the precision fasteners you need for a full engine assembly, eliminating guesswork and ensuring proper torque specifications across cam, primary, transmission, and auxiliary systems. Whether you're freshening an engine or building from the ground up, this comprehensive kit reduces downtime and guarantees you won't overlook a single fastening point.

Each bolt is manufactured to exacting tolerances, engineered to handle the vibration and stress loads endemic to high-performance riding. Socket-head design provides superior holding power and cleaner aesthetics compared to slotted or Phillips fasteners—critical when you're investing in quality machine work and precision components.
