Ford SFI Billet Flywheel '92-'08 Ford Mod 4.6L

The PRW Industries Ford SFI Billet Flywheel for '92–'08 Ford Modular 4.6L engines is a premium performance replacement designed for builders and enthusiasts serious about engine reliability and compatibility. This SFI 1.1-certified billet steel flywheel features a 164-tooth ring gear and 50-ounce external balance, engineered to work seamlessly with factory and aftermarket clutch systems across fourth and fifth-generation Mustangs, Explorers, and truck applications running the 4.6L modular engine family.

Built from billet steel rather than cast iron, this flywheel eliminates the risk of ring gear slip, cracking, and premature wear that can occur with OEM components under high-RPM or boosted conditions. The 164-tooth design maintains compatibility with stock starter motors and most performance starters, while the 50-ounce external balance point is matched to the 4.6L's specific harmonic characteristics. SFI 1.1 certification ensures this component meets sanctioning body standards for drag racing and circle track competition, a credential that matters if your build is headed to the track or requires documented safety approval.

This flywheel is ideal for street performance builds, naturally aspirated or turbocharged applications, and restoration projects where durability and correct balance are non-negotiable. The billet construction resists fatigue better than cast alternatives, making it a logical upgrade for engines pushed beyond stock power levels or subjected to frequent clutch engagement cycles. Fitment is direct for any '92–'08 4.6L modular engine platform, whether in Mustang, F-150, Expedition, or Navigator applications.
