SBC 168 Tooth Flexplate - SFI - Int. Balance

The ATI 915541 SBC 168 Tooth Flexplate is specifically designed for small-block Chevrolet engines that are paired with modern automatic transmissions or torque converters. This component is crucial for transferring rotational force between the engine's crankshaft and the torque converter, while also accommodating thermal expansion and vibration. Flexplates are essential for any SBC engine swap, street performance build, or high-horsepower application.

Engineered by ATI Performance, this 168-tooth flexplate is SFI certified, ensuring it meets strict safety standards for both competition and street use. Its internal balance design aligns with your engine's crankshaft balance specifications, which helps to reduce vibration and prevent damage to seals, bearings, and transmission components. The flexplate is constructed to withstand repeated shock loads from aggressive acceleration and high-RPM operation, featuring precision-machined teeth for reliable starter engagement.

Mechanics and engine builders prefer the ATI 915541 when rebuilding SBC powerplants for street rods, muscle cars, or competition vehicles. The internally-balanced design is particularly important when using modern LS or traditional SBC blocks with updated crankshafts, as improper balance can lead to harmful harmonics that degrade transmission life and cause driveline wear. Installation requires proper torque specifications to ensure optimal performance.
