Key Features

ARP's Flexplate Bolt Kit features several advanced design elements and materials that set it apart from standard OEM hardware:

• Forged Aerospace Alloy Construction: Crafted from high-strength aerospace-grade steel, these bolts are forged and heat-treated to withstand extreme engine loads and vibrations, reducing the risk of bolt failure under stress.
• Flat 12-Point Head Design: The unique head shape allows for increased torque application and easier installation in tight engine bays, providing a secure grip and reducing the risk of stripping or cam-out during tightening.
• Enhanced Shank Diameter: The larger-than-stock shank diameter improves the fastener's shear strength and register, ensuring a more robust connection between the flexplate and crankshaft.
• Black Oxide Finish: The durable black oxide coating offers excellent corrosion resistance, maintaining the fasteners' integrity over time, even in harsh environments.
• Precision Thread Rolling and Machining: The bolts undergo a meticulous manufacturing process that ensures consistent thread quality and optimal fitment, reducing installation issues and promoting long-term reliability.
• Compatibility: Designed to fit multiple Jeep models with 4.0L Inline 6-cylinder engines, these bolts are a versatile upgrade for various applications, including rebuilds and performance modifications.

Construction & Design

The ARP Flexplate Bolt Kit is engineered with a focus on strength, durability, and ease of installation. The aerospace alloy steel used in these fasteners provides a significant upgrade over OEM hardware, offering increased shear and tensile strength. The flat 12-point head design not only facilitates better torque application but also ensures a secure fit in confined spaces, reducing the risk of stripping during installation.

Each bolt is heat-treated and precision-machined to exact specifications, ensuring a perfect fit and consistent performance. The black oxide finish enhances corrosion resistance, making these bolts suitable for off-road use, exposure to moisture, and other challenging conditions. Overall, the design choices made by ARP result in a fastener that maintains its integrity under demanding engine loads, helping to prevent flexplate failures and ensuring smooth operation.

Performance & Reliability

While these bolts are not rated with specific horsepower or torque gains, their primary benefit lies in their superior strength and reliability. By replacing OEM flexplate bolts with ARP's Pro Series fasteners, you reduce the risk of bolt stretch, fatigue, or failure, especially during high-stress driving conditions. This upgrade supports the overall integrity of your engine's rotating assembly, contributing to consistent performance and peace of mind during demanding driving scenarios.

Installation & Fitment

The ARP Flexplate Bolt Kit is designed for straightforward, bolt-on installation. These fasteners are compatible with a range of Jeep models equipped with 4.0L Inline 6-cylinder engines. No special tools beyond standard socket sets are required, and the flat 12-point head design simplifies tightening in tight spaces. It is recommended to follow ARP's torque specifications during installation to ensure proper clamping force and to prevent over-tightening. Always inspect the bolts for proper thread engagement and cleanliness before installation.
