Rear Motor Cover Bolt Kit - 12pt. LS1/LS2

The Rear Motor Cover Bolt Kit – 12pt. LS1/LS2 by ARP is designed for LS engine builders and enthusiasts who prioritize reliability and precision in their engine assembly. This fastener kit replaces the stock rear motor cover bolts on GM's LS1 and LS2 engines, addressing concerns about bolt stretch, corrosion, and potential fastener failure during high-rpm operation.

Manufactured from proprietary alloy steel, ARP fasteners feature 12-point heads that enhance grip and minimize cam-out risk compared to standard six-point bolts. The 12-point design ensures even distribution of clamping force across the fastener head, which is crucial when adhering to torque specifications on precision aluminum LS engine blocks. Each bolt is pre-lubricated with ARP's anti-seize compound, facilitating consistent tension during installation.

This kit is ideal for street performance builds, racing applications, and engine rebuilds, ensuring that the rear cover remains secure under various conditions. Both professionals and home mechanics trust ARP fasteners for their durability and performance, preventing catastrophic failures that could compromise engine integrity.
