1983 Pontiac Firebird Flywheels and Flexplates

Vehicles with automatic transmissions have a flex plate. The flex plates connects the engine and transmission. Most flex plates are made of a thick piece of sheet metal with bolt holes for the torque converter and teeth for the starter. The job of a flex plate is to allow for expansion of the torque converter as engine RPM increases. The constant expansion and contraction of a flex plate over time can result cracks and/or shearing of the flex plate. A damaged flex plate can create serious (expensive) damage. Broken flex plates can not be repaired, they must be replaced. ATP flex plates are made of high quality steel and contain the correct bolt hole spacing and ring gear teeth just like the original part to ensure long life and durability

Product Features:

• Balanced to factory specs
• Fit and function like the original parts
• Restores normal operation

Flywheel hot spots can cause chatter. Resurfacing a flywheel doesn’t always remove hot spots. The flywheel may look shiny and pretty, but the hot spots will often still be there. Service the System by replacing the flywheel and the clutch set at the same time. All flywheels come with a new ring gear.

Product Features:

• Casting process closely monitored to ensure uniform density and balance retention
• Eliminates chance of chatter due to hot spots not always removed by resurfacing
• New ring gear ensures positive starter engagement
• Engineered to properly fit the intended application with no modifications

Constructed of thicker than stock steel plate to withstand the stress of high stall speed converters and high RPM engine. Zinc dichromate plated to resist rust and corrosion. Meets SFI specification 29.1 for racing.

Product Features:

• Thicker Than Stock Steel Plate
• Ring Gear Securely Welded
• Dual Bolt Patterns
• Zinc-Dichromate Plated To Resist Corrosion
• Withstands High Torque and RPM

LuK: New flywheels are a smart alternative! The flywheel is an integral part of clutch replacement. It must provide a smooth, flat surface for proper clutch operation. Pairing your clutch set with a new flywheel is a smart, cost-effective alternative to resurfacing. All new – never remanufactured – every component is engineered and manufactured to OE specifications, including ring gear and dowel pins.

As performance levels increase, an O.E. style flexplate just won’t cut it and a stronger option is a necessity to prevent transmission and/or converter failure. B&M has you covered with our high performance flexplate designed for 1955-85 GM small block (internally balanced) V8 engines along with 4.3L V6 engines. Also fits 1990 and earlier GM big block (internally balanced) V8 engines with two piece rear main seal. Features include high tensile strength steel construction to resist elongation and cracking, dual bolt pattern 10.75 or 11.5 inch converter mounting locations, 168 tooth ring gear with double-sided welds for added strength and comes with SFI 29.1 safety certification insuring the ultimate in safety and performance. The assembly is then Zinc plated and treated with a Chromate Conversion Coating for added corrosion resistance and durability. B&M SFI approved flexplates are ideal for extreme duty race applications as well as street cars, tow vehicles or other vehicles needing the added protection and toughness that B&M has been delivering since 1953. Compatible with Powerglide, TH350, TH400 and TH700R4 automatic transmissions.
