ARP Flexplate Bolt Kit # 234-2902
Designed to “take the torque”
Every bit of engine torque produced by your LT1 or LT4 must pass through the flexplate before it reaches the transmission. Whether you're making 450 horsepower or 1,500+, the flexplate bolts are responsible for transmitting that power reliably every single time the engine accelerates, decelerates, shifts, and launches.
While factory hardware is adequate for stock applications, performance builds place substantially greater loads on the flexplate-to-crankshaft connection. Increased torque, higher RPM, larger torque converters, transbrake launches, sticky tires, and forced induction all place additional stress on these fasteners.
That's why ARP developed the Pro Series Flexplate Bolt Kit.
Manufactured from premium 8740 chromoly steel and heat-treated for exceptional strength, these fasteners provide significantly greater durability, clamp load retention, and fatigue resistance than OEM hardware. Designed specifically for Gen V LT applications, the ARP 234-2902 kit is the ideal upgrade anytime a flexplate is being removed or replaced.
Why Upgrade to ARP Flexplate Bolts?
Superior Strength
ARP Pro Series fasteners are manufactured from premium 8740 chromoly steel and rated at approximately 190,000 PSI tensile strength. This provides a substantial increase in strength over typical production fasteners.
Improved Clamp Load Retention
The primary job of a flexplate bolt is maintaining proper clamping force between the flexplate and crankshaft.
When clamp load is compromised, movement can occur between the flexplate and crank flange, potentially leading to fastener failure, damaged flexplates, crankshaft wear, or transmission issues.
ARP fasteners are engineered to maintain preload under extreme operating conditions.
Increased Fatigue Resistance
Unlike a single high-load event, flexplate bolts experience millions of load cycles throughout their service life.
Every shift, every RPM change, and every torque event places stress on the hardware.
ARP's material selection, heat treatment process, and manufacturing precision help provide exceptional fatigue resistance for long-term reliability.
Designed for High Horsepower Applications
Any time the transmission is removed and the flexplate becomes accessible is the perfect opportunity to upgrade the hardware securing it.
Considering the labor involved in transmission removal, upgrading to ARP hardware is inexpensive insurance.

Installation Notes
Always inspect the flexplate and crankshaft flange for wear or damage before installation.
Clean all mating surfaces thoroughly.
Follow ARP torque specifications and installation instructions.
Use the recommended ARP fastener lubricant where specified.
Never reuse damaged or questionable flexplate hardware.
The GMS Recommendation
Flexplate bolts are one of those components that nobody sees—but they are absolutely critical to drivetrain reliability.
When you're investing thousands of dollars into an engine build, transmission, converter, blower, turbo system, or fuel system, the hardware connecting your flexplate to the crankshaft should never be an afterthought.
ARP Pro Series Flexplate Bolts provide the strength, durability, and clamp load necessary to handle the demands of today's high-horsepower LT platforms.
Whether you're building a mild street car or a four-digit horsepower race vehicle, this is cheap insurance that helps keep your drivetrain together when it matters most.
Go Faster. Stay Cooler. Build It Right.
