Don’t waste time and money relocating existing coil packs, formed from black or polished CNC-machined aluminum, JEGS LS Coil Valve Cover Adapter Kits accept three different coil-pack configurations. The truly innovative way to add vintage 1958-1986 Small Block Chevy perimeter bolt valve covers to an LS engine, these adapters bolt to your engine while the coils bolt to the adapter plates. The coils can then be hidden by your valve covers. Once valve covers are installed the assembly will measure 5” tall from the bottom of the adapter to the top of the valve cover.
