HP Woodruff Key BBF BBF FE 3/16 x 1.750 2pk

The HP Woodruff Key BBF FE 3/16 x 1.750 2pk by Pioneer is an essential crankshaft fastening component designed for big-block Ford (BBF) and FE engine platforms. As a seasoned mechanic, you know that the woodruff key is often overlooked but absolutely critical—it prevents crankshaft-to-pulley slippage and maintains precise ignition timing during high-rpm operation. This two-pack delivers genuine Pioneer quality for engine rebuilds, performance upgrades, or routine maintenance on classic and modern Ford muscle cars running vintage big-block architecture.

Constructed from hardened steel in natural finish, this woodruff key measures 3/16 inch wide by 1.750 inches long—the exact OEM spec for proper fit in the crankshaft keyway slot. Unlike flat keys, the woodruff design uses a semi-circular cross-section that locks into a matching semicircular pocket, providing superior load distribution and resistance to shear stress during acceleration and deceleration cycles. The natural steel finish resists corrosion under typical engine bay conditions, while the precision manufacturing ensures zero play between crank and harmonic balancer, a detail that matters when you're chasing horsepower or rebuilding a numbers-matching engine.

This kit suits any builder or restorer working on BBF 427, 454, or FE 427 applications, as well as performance-oriented restorations where original hardware integrity is non-negotiable. Installation is straightforward—slide the key into the crankshaft slot before mounting the harmonic balancer, ensuring the curved face seats fully against the keyway. Buy this two-pack to keep a spare on hand; having an extra woodruff key available eliminates downtime if one becomes damaged during removal. Compatible with all standard Ford big-block cranks using this keyway profile, making it a must-have for any serious mechanic's parts drawer.
