Upgrade your LS engine swap with these premium Truck Side Bolt Ignition Coil Brackets, designed to securely mount your D585 heat sink-style ignition coils on valve covers. These brackets are a direct replacement for factory components, ideal for LSX swaps, engine rebuilds, and performance builds.

These brackets are precision-engineered to fit radiator-style (D585) heat sink coils, compatible with 5.3L LS engines including LM7, LR4, LQ4, LQ9, LY2, LY5, LY6, LC9, LC8, LMG, LH6, L59, L76, L92, L96, and L98. They provide a secure, factory-style mounting solution to keep your ignition coils firmly in place, eliminating misalignment issues that can cause performance problems.

Crafted from high-quality billet aluminum alloy with a durable, corrosion-resistant finish, these brackets offer excellent heat resistance and long-lasting reliability, even under high engine temperatures and harsh operating conditions. CNC-machined to tight OEM-level tolerances, they ensure perfect coil alignment for consistent spark delivery, while the vibration-resistant design prevents coil movement during engine operation. The complete kit includes all necessary mounting hardware for a quick, bolt-on installation with no modifications required.
