LS Coil D585

The LS Coil D585 from Allstar Performance is a high-output direct-fit ignition coil pack engineered specifically for GM LS-series engines. This black coil pack replaces OEM ignition components and delivers the reliable spark delivery modern LS powerplants demand, whether you're running a stock engine, a modified street build, or a track-focused application. Designed for technicians and enthusiasts who need a proven drop-in solution, the D585 eliminates guesswork in ignition system upgrades.

The LS Coil D585 uses a high-output design that improves spark strength and ionization efficiency compared to original equipment, resulting in better cold-start performance and more consistent combustion across the RPM range. The coil's direct-fit configuration means no adapter harnesses or custom wiring—it seats directly into the factory coil pack location on LS cylinder heads. Quality construction and durable materials ensure long-term reliability in high-heat engine bay environments, making it suitable for street, strip, and competition use without premature failure or voltage dropout.

This coil pack is ideal for LS engine owners upgrading ignition systems, troubleshooting weak spark issues, or performing routine maintenance on vehicles ranging from third-generation Camaros and Corvettes to modern Silverados and Trailblazers. Installation is straightforward—simply remove the old coil pack and insert the D585 into the same cavity. Technicians and DIY builders trust Allstar Performance's LS components for their accuracy and fit, making the D585 a reliable choice for anyone committed to maximizing LS-series engine performance.
