ARP GM LS 12pt Bellhousing Bolt Kit

When building or upgrading a GM LS engine, securing the bellhousing with confidence is critical for drivetrain integrity and alignment. This ARP Bellhousing Bolt Kit provides the necessary strength and precision to fasten your transmission to the engine block, outperforming factory hardware under demanding conditions.

ARP (Automotive Racing Products) fasteners are renowned for their superior tensile strength and fatigue resistance, making them a preferred choice for high-performance and race applications. These premium bolts prevent bellhousing flex and ensure a secure, long-lasting connection, critical for proper transmission operation and reducing stress on other drivetrain components. The 12-point head design offers increased wrench engagement compared to traditional hex heads, allowing for higher, more consistent torque values without rounding off the fastener. Each bolt is precision-machined from a proprietary ARP alloy, heat-treated, and threads rolled after heat treatment for maximum strength and durability. This kit is designed for optimal fit and reliable performance across various GM LS engine and transmission combinations.
