Flywheel Bolt Kit Bert / Brinn

The Quarter Master Flywheel Bolt Kit for Bert/Brinn high-performance flexplates is engineered for serious enthusiasts and engine builders who demand reliability in extreme rotating assembly applications. Whether you're assembling a race engine, upgrading a street performance build, or restoring a classic muscle car, this fastener kit addresses one of the most critical stress points in any drivetrain—the connection between the flywheel and crankshaft. Proper fastening at this interface is non-negotiable; any loosening or failure here risks catastrophic engine damage and potential safety hazards.

This bolt kit is specifically engineered to work with Bert and Brinn aluminum flexplate designs, which are popular in bracket racing, street rod, and high-horsepower street applications due to their lightweight construction and strength-to-weight ratio. Quarter Master fasteners are manufactured to exacting tolerances and typically feature premium materials that resist corrosion, fatigue, and the repeated stress cycles inherent to high-rpm operation. The kit's compact footprint (3.95 x 0.85 x 6.35 inches) and lightweight design (0.43 lbs) ensure that nothing unnecessary adds rotational mass, preserving the efficiency gains your flexplate upgrade provides.

This flywheel bolt kit is ideal for builders working with late-model small-block and big-block engines, particularly those converting to automatic transmissions with billet flexplates. Installation is straightforward for anyone with basic mechanical knowledge and a torque wrench—critical for achieving the proper clamping load without over-tightening. Whether you're prepping for the drag strip, building a street performance engine, or restoring a high-powered restomod, using factory-grade fasteners from a trusted manufacturer like Quarter Master ensures your rotating assembly stays together under the most demanding conditions.
