Description
Bellhousing bolts endure extreme forces during acceleration and gear changes—stock fasteners can stretch or fail under sustained power, risking catastrophic drivetrain separation. ARP’s 129-0901 kit replaces those vulnerable OEM bolts with 4140 chromoly fasteners engineered for durability and reliability in high-performance applications. Whether you’re running naturally aspirated or forced induction, these bolts deliver the clamping force your transmission needs to stay secure.
