ARP Main Stud Kit for Mopar 318 340 360 2 Bolt 140-5401

ARP Main Stud Kit for Mopar 318 340 360 2 Bolt 140-5401

The ARP Main Stud Kit for Mopar 318, 340, and 360 engines is engineered to provide superior strength and reliability for your high-performance applications. Unlike traditional main bolts, this stud kit replaces the factory main bolts with heavy-duty studs that ensure optimal clamping force and stability. This is critical for maintaining the integrity of the engine block under high-stress conditions, especially during rigorous racing and tuning activities.

Constructed from high-grade materials, the ARP main studs offer enhanced tensile strength and resistance to elongation. This results in a more secure fit and helps prevent issues such as stud stretch, which can jeopardize the engine's performance. The precision-machined threads ensure a perfect fit, allowing for uniform torque distribution across all main caps, which is essential for achieving maximum power and efficiency.

By using ARP's advanced technology, this main stud kit contributes significantly to increased engine durability and reliability. The use of studs over bolts also facilitates easier installation and removal, allowing for quick engine disassembly when needed without compromising the stud’s integrity. This feature proves advantageous for builders and tuners who frequently access the engine for modifications or maintenance.

FITMENT: Compatible with Mopar 318, 340, and 360 engines utilizing a 2-bolt main configuration.
