Mopar Flex Plate Bolts

MR. GASKET Mopar Flex Plate Bolts are precision-engineered fasteners designed for high-performance Mopar engines where durability and secure torque retention are non-negotiable. The flex plate—that critical component between your engine and transmission—demands bolts that won't loosen under thermal cycling, vibration, and repeated load reversals. This kit addresses a common pain point for Mopar enthusiasts: OEM flex plate bolts that fail to maintain clamp load, leading to transmission slippage, noise, and potential catastrophic drivetrain damage. Whether you're building a street engine, restoring a classic Dodge or Plymouth, or upgrading a performance platform, quality flex plate bolts are foundational to reliability.

These MR. GASKET bolts are manufactured to exacting standards with improved material composition and thread geometry that resists galling and ensures consistent torque values across multiple tightening cycles. The precision finish and dimensional accuracy prevent the common issue of bolt stretch and preload loss that plagues inferior aftermarket fasteners. MR. GASKET's decades of engine gasket and fastener expertise mean these bolts are engineered specifically for Mopar flex plate applications, accounting for the unique bolt patterns and torque specifications of Chrysler, Dodge, and Plymouth powerplants. The compact kit (4.6 x 0.85 x 7.3 inches) ships ready for installation—no sorting or measuring required.

Mopar flex plate bolt replacement is essential for any engine rebuild, transmission service, or performance upgrade on classic and modern Chrysler-platform vehicles. Mechanics and DIY builders alike rely on MR. GASKET fasteners to eliminate comebacks caused by loose flex plates and associated vibration complaints. Installation is straightforward—remove the old bolts, clean the flex plate and crankshaft flange thoroughly to remove debris and old loctite residue, then install the new fasteners with a torque wrench set to manufacturer specifications (typically 55–65 lb-ft for most Mopar applications). Always use a thread-locking compound (medium-strength preferred) and verify torque after 50 miles of driving to confirm preload retention.
