Pro Series Flexplate SFI 29.1 SBF 164T

The Pro Series Flexplate SFI 29.1 SBF 164T is a high-performance flexplate engineered for small-block Ford (SBF) engines running automatic transmissions in street, strip, and drag racing applications. This component replaces the stock flexplate and serves as the critical mechanical bridge between your engine's crankshaft and torque converter, absorbing rotational forces while transmitting power to the transmission. Whether you're building a stock-appearing street cruiser or a serious bracket racer, a quality flexplate is non-negotiable for reliability and safety.

This PRW Industries flexplate features SFI 29.1 certification, the industry standard for impact and stress resistance in high-horsepower applications, meaning it has been independently tested and validated to handle extreme loads without failure or shattering. The 164-tooth design is purpose-built for small-block Ford engines, interfacing directly with your starter motor for reliable cold cranks and precision ignition timing through the reluctor ring pattern. At 8.78 lbs, it's manufactured with balanced metallurgy to minimize vibration and reduce parasitic losses, critical factors when you're chasing tenth-second improvements or maximizing street performance. The compact 15-inch design maintains factory clearance while delivering uncompromising durability for both naturally aspirated and supercharged/turbocharged platforms.

This flexplate is ideal for any SBF engine builder—from mild 289 or 302 restorations to 408-stroker monsters—that demands OEM fit with race-proven reliability. Installation requires engine removal in most vehicles and should be torqued to manufacturer specifications using a dial indicator for runout verification; professional machine shops or experienced mechanics will ensure proper balancing and alignment with your existing torque converter. The SFI 29.1 certification provides peace of mind at the strip and peace of mind on the street, making it the specification choice for serious Ford enthusiasts who refuse to compromise on powertrain safety.
