Overview

Meet the ARP 2442901 Pro Series Flexplate Bolt Kit, a premium-grade fastener set designed to meet the demands of Gen II/LS small block Chevrolet builds. These bolts are forged from aerospace-grade alloy and undergo heat treatment before thread rolling and precision machining, delivering a blend of toughness and accuracy that matters when you are assembling a high-performance drivetrain.

Key design advantages

Key features work together to provide robust, reliable mounting without adding unnecessary weight. The exclusive flat 12-point head design offers a broader contact area for improved wrench engagement, while a larger-than-stock shank diameter increases strength and helps maintain precise register between flexplate and crank.

  • aerospace-grade alloy forging for a high strength-to-weight ratio
  • heat-treated before thread rolling and machining for uniform hardening
  • flat 12-point head design for secure wrenching and even torque distribution
  • increased shank diameter to bolster strength and register accuracy

Specifications at a glance

  • Part number: ARP 244-2901
  • Thread size: M11 x 1.5
  • Wrenching size: 3/4 inch

What this means in real use

For builders, this kit offers peace of mind during installation and on the dyno. The combination of materials and machining practices is designed to resist galling and wear under torque and vibration, helping you maintain proper alignment over time. While results depend on the overall build and driving conditions, upgrading to Pro Series bolts can contribute to more consistent, predictable mounting behavior in many Gen II/LS configurations.

Installation considerations

Always verify fitment for your specific crank and flexplate, and follow ARP’s torque specs and lubrication recommendations. As with any high-performance fastener set, professional installation is recommended to maximize preload consistency and service life.
