Manufactured from certified billet steel, these flywheels will not break under the stress of high RPM or the punishment of racing. Varying from 25 to 50 pounds based on application, most Hays flywheels are drilled with both the Borg & Beck and Long clutch patterns. All are precision-balanced to either Detroit (external) or neutral (internal) specifications (1.1 SFI-certified).Notes: - Flywheel thicker than stock; may require bellhousing spacing (Lakewood bellhousing will eliminate interference)
- Possible interference between ring gear and bellhousing; may require dial indicating of bellhousing
