Chevy V8 168 Tooth Alum. Flexplate w/Steel Gear

The Chevy V8 168 Tooth Aluminum Flexplate with Steel Gear from CSR Performance is a critical drivetrain component engineered for high-performance small-block and big-block Chevrolet V8 engines paired with automatic transmissions. This flexplate serves as the critical interface between your engine's crankshaft and torque converter, absorbing rotational harmonics while transferring power smoothly to your transmission. Built for street applications, mild boost scenarios, and weekend warrior builds, this component replaces worn or damaged factory flexplates that can cause vibration, noise, or catastrophic drivetrain failure if neglected.

Constructed from lightweight aluminum, the 168-tooth design accommodates modern starter motors and torque converters while maintaining precise balance and concentricity critical for automatic transmission operation. The integrated steel gear ring bolsters durability where it matters most—at the teeth that engage the starter motor—preventing gear stripping and premature wear under repeated starting cycles or high-torque launches. At just 6.15 pounds, this aluminum flexplate significantly reduces rotating mass compared to cast-iron factory units, lowering engine load and improving throttle response. The 15.1-inch diameter and 1.5-inch height conform to standard Chevy V8 bolt patterns, ensuring drop-in compatibility without additional machining or modification.

This flexplate is ideal for Chevy V8 enthusiasts running Turbo 350, Turbo 400, 700R4, or 4L60E transmissions on street rods, restorations, and performance builds seeking reliability without weight penalty. Installation requires removing the transmission and bellhousing; bolt the flexplate to the crankshaft flange with proper torque specifications and balance the assembly if running a new torque converter. Verify transmission compatibility and starter clearance before purchase, as some aftermarket starters or custom bellhousings may require fitment confirmation.
