Coil Bracket Bolt Kit 6pt Mopar 5.7/6.1L Hemi

The ARP Coil Bracket Bolt Kit 6pt Mopar 5.7/6.1L Hemi is engineered for engine builders and performance mechanics who demand reliability in high-stress applications. If you're upgrading a third-generation Hemi engine with custom heads, turbo kits, or supercharger systems, factory fasteners simply won't cut it—they lack the tensile strength and preload consistency needed under extreme combustion pressures. This 16-piece chromoly bolt set replaces OEM coil bracket hardware with premium ARP fasteners that maintain clamp load through thermal cycling and vibration.

ARP's proprietary chromoly steel construction delivers superior strength-to-weight ratio compared to standard steel, allowing consistent preload retention that prevents coil pack shifting and electrical failures. Each bolt is finished in black oxide for corrosion resistance and aesthetic consistency with modern engine bays. The 6-point head design distributes load evenly across the socket, eliminating the stripping issues common with 12-point fasteners under high torque. Precision tolerances throughout the set ensure repeatability across all 16 fasteners—critical when bolt preload variation causes uneven coil mounting and potential misfire conditions.

This kit is essential for 5.7L and 6.1L Hemi engines in Dodge and Jeep platforms experiencing high-RPM duty, turbocharging, or custom tuning. Street performance builds, drag racing applications, and engine swaps all benefit from fastener upgrade; even mild boosted applications see reliability gains. Installation requires standard hex socket tools and adherence to ARP's torque specifications—consult your engine manual or ARP's technical documentation for Hemi-specific preload values. The complete 16-piece set ensures you have all brackets covered without mixing fastener types or grades.
