Rear Motor Cover Bolt Kit Mopar 5.7/6.1L Hemi

The Rear Motor Cover Bolt Kit Mopar 5.7/6.1L Hemi from ARP is an essential fastener upgrade for builders and enthusiasts working on high-performance Chrysler, Dodge, and Jeep platforms equipped with legendary Hemi engines. This kit addresses a critical weak point in factory hardware—the rear motor cover bolts that secure the timing cover and oil gallery passages at the back of the engine block.

Whether you're performing a full rebuild, upgrading to forced induction, or simply running higher boost pressures and cylinder pressures, OEM fasteners can stretch and fail under sustained load, compromising seal integrity and risking catastrophic oil leaks. ARP bolts are manufactured from premium-grade alloy steel and feature precise thread rolling and hardening processes that deliver superior tensile strength compared to factory hardware.

The Rear Motor Cover Bolt Kit Mopar 5.7/6.1L Hemi utilizes ARP's proprietary fastening technology to eliminate bolt stretch, ensuring consistent clamp load across thermal cycles and high-rpm operation. This precision engineering prevents galling and seizing that often occurs with stainless or inadequate fasteners, making installation straightforward for any competent mechanic or DIY builder.
