Pro Series Flexplate SFI 29.1 82-95 SBF 157T

The Pro Series Flexplate SFI 29.1 82-95 SBF 157T is a purpose-built flexplate designed for Small Block Ford engines requiring maximum durability and safety in high-performance applications. This component serves as the critical interface between your engine's crankshaft and automatic transmission, absorbing rotational forces while allowing controlled flex to protect drivetrain components. Whether you're building a street performance engine, upgrading a classic Fox Body, or assembling a serious bracket racing powerplant, a quality flexplate is non-negotiable for reliability and longevity.

PRW Industries engineered this flexplate with SFI 29.1 certification, the industry standard for high-rpm dynamic balancing and structural integrity on modified engines. The 157-tooth ring gear design is purpose-matched to Small Block Ford applications, ensuring precise starter engagement and eliminating the risk of gear slip or premature wear. Constructed from premium nodular iron with precision-machined surfaces, this flexplate accommodates the specific bolt pattern and torque characteristics of 1982–1995 SBF platforms while maintaining concentricity critical for vibration control. The engineering behind SFI certification means this part has been tested to withstand shock loads and thermal cycling that stock components simply cannot handle.

Serious engine builders and transmission shops rely on PRW flexplates when power exceeds stock parameters—turbocharged builds, supercharged applications, or any combination producing sustained high-rpm operation. The Pro Series Flexplate SFI 29.1 82-95 SBF 157T is essential for C4, C5, AOD, and other automatic transmissions paired with modified 289, 302, 351W, and related small block variants. Installation requires standard flexplate removal and replacement procedures, with torque specifications matching factory Small Block Ford guidelines. Choose this flexplate when your engine's output demands the engineering and certification that protects both your investment and your drivetrain's survival.
