High-Strength Motor Mount Security for Gen III Hemi

Engine movement is the enemy of performance. Keep your Mopar 5.7L or 6.1L Gen III Hemi firmly anchored to your chassis with this professional-grade motor mount bolt kit from Auto Racing Products (ARP). Designed for enthusiasts who demand the highest level of structural integrity, these 12-point bolts replace weak factory hardware with high-tensile 8740 chromoly steel.

Why Upgrade Your Motor Mount Bolts?

  • Superior Strength: Rated far higher than standard OEM fasteners
  • 12-Point Design: Provides better torque application and clearance
  • Corrosion Resistant: Finished in a durable black oxide coating
  • Precision Fit: Specifically engineered for Mopar 5.7L/6.1L Hemi applications
  • Set of 8: Complete kit for a hassle-free installation

Under heavy acceleration or aggressive driving, stock motor mount bolts can stretch or fatigue, leading to unwanted engine shift and potential drivetrain damage. This ARP kit eliminates those concerns by providing a rigid, secure connection between your engine block and the mounts. The 12-point head profile is not only aesthetically pleasing but also allows for more precise torquing in confined spaces. Whether you are building a street machine or a dedicated track car, these fasteners provide the reliability you need to push your Hemi to the limit. Trust your build to the industry-leading hardware available at GGCRACING.
