Prolite flywheels are preferred for road racing or rally racing and carry somewhat reduced low-speed drivability versus a heavier stock flywheel. Material is properly distributed for maximum strength, good heat tolerance, and rigidity. The flywheel is forged, CNC-machined, and dynamically computer balanced for smooth high-RPM reliability, and one-piece construction eliminates warped inserts or loose ring gears. It is fully serviceable and can be resurfaced with no additional parts required. Counterweight bolts (5\/16\"-18 x 1\/2\") are included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFriction Surface Diameter: 10.5 in\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 14.4 lbs\u003c\/li\u003e\n\u003cli\u003eConstruction: Chromoly steel, forged and CNC-machined\u003c\/li\u003e\n\u003cli\u003eSFI Rating: 1.1\u003c\/li\u003e\n\u003cli\u003eRing Gear Mount: Flat\u003c\/li\u003e\n\u003cli\u003eIncludes: Counterweight bolts (5\/16\"-18 x 1\/2\")\u003c\/li\u003e\n\u003cli\u003eServiceable: Yes, resurfaceable with no additional parts required\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Race use\u003c\/li\u003e\n\u003cli\u003ePart Number: 600412\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1982 Ford Mustang GL\u003c\/li\u003e\n\u003cli\u003e1982 Ford Mustang GLX\u003c\/li\u003e\n\u003cli\u003e1982 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1983 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1984 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1985 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1986 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1987 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1988 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1989 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1990 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1991 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1992 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1993 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1994 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1995 Ford Mustang GT\u003c\/li\u003e\n\u003cli\u003e1984 Ford Mustang GT-350 20th Anniversary\u003c\/li\u003e\n\u003cli\u003e1995 Ford Mustang GTS\u003c\/li\u003e\n\u003cli\u003e1979 Ford Mustang Ghia\u003c\/li\u003e\n\u003cli\u003e1970 Ford Mustang Grande\u003c\/li\u003e\n\u003cli\u003e1971 Ford Mustang Grande\u003c\/li\u003e\n\u003cli\u003e1972 Ford Mustang Grande\u003c\/li\u003e\n\u003cli\u003e1973 Ford Mustang Grande\u003c\/li\u003e\n\u003cli\u003e1982 Ford Mustang L\u003c\/li\u003e\n\u003cli\u003e1984 Ford Mustang L\u003c\/li\u003e\n\u003cli\u003e1984 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1985 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1986 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1987 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1988 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1989 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1990 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1991 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1992 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1993 Ford Mustang LX\u003c\/li\u003e\n\u003cli\u003e1970 Ford Mustang Mach 1\u003c\/li\u003e\n\u003cli\u003e1971 Ford Mustang Mach 1\u003c\/li\u003e\n\u003cli\u003e1972 Ford Mustang Mach 1\u003c\/li\u003e\n\u003cli\u003e1973 Ford Mustang Mach 1\u003c\/li\u003e\n\u003cli\u003e1993 Ford Mustang SVT Cobra\u003c\/li\u003e\n\u003cli\u003e1994 Ford Mustang SVT Cobra\u003c\/li\u003e\n\u003cli\u003e1995 Ford Mustang SVT Cobra\u003c\/li\u003e\n\u003cli\u003e1993 Ford Mustang SVT Cobra R\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWarning: This product can expose you to chemicals including carbon black, glass wool fibers, or silica (in clutch discs), chromium and nickel, which are known to the State of California to cause cancer or birth defects or other reproductive harm.
