S/S Coil Bracket Bolt Kit - 12pt. LS1/LS2

The S/S Coil Bracket Bolt Kit for LS1/LS2 engines delivers the fastening reliability that serious engine builders demand when securing ignition coil packs to the cylinder head. Whether you're assembling a stock restoration, high-output street engine, or competition platform, these ARP 12-point bolts eliminate the risk of fastener failure under vibration, thermal cycling, and sustained boost conditions. Coil pack mounting security is non-negotiable—a loose bracket can cause intermittent spark delivery, misfire codes, and catastrophic engine damage in extreme applications.

ARP's stainless steel construction resists corrosion and heat degradation far longer than OEM zinc-plated fasteners, making this kit ideal for forced-induction builds, engine bays with custom headers, or vehicles stored in harsh climates. The 12-point head design prevents socket rounding and ensures repeatable torque values during installation and future service intervals. Stainless steel alloy provides superior tensile strength without the brittleness that can plague aftermarket fastener alternatives, maintaining clamp load even as engine temperatures fluctuate between idle and full throttle.

LS1 and LS2 owners upgrading to aftermarket coil-on-plug systems, or simply replacing worn factory hardware, will appreciate the precision engineering and longevity this kit provides. Installation is straightforward—remove original fasteners, clean the mounting surface, and install ARP bolts to factory torque specification using the 12-point socket included or sold separately. This kit is essential for any LS engine refresh, supercharger or turbo installation, or high-mileage restoration where reliability and corrosion resistance matter most.
