LS Coil D585

The LS Coil D585 from Allstar Performance is a high-output direct-fit ignition coil pack designed specifically for GM LS-series engines. This coil pack replaces OEM ignition components and provides the reliable spark delivery that modern LS powerplants require, whether for stock engines, modified street builds, or track-focused applications.

Engineered for both technicians and enthusiasts, the D585 offers a drop-in solution that eliminates guesswork in ignition system upgrades. Its high-output design enhances spark strength and ionization efficiency compared to original equipment, leading to improved cold-start performance and consistent combustion across the RPM range. The coil's direct-fit configuration allows for easy installation without the need for adapter harnesses or custom wiring.

Ideal for LS engine owners looking to upgrade their ignition systems or troubleshoot weak spark issues, this coil pack is compatible with a range of vehicles, including third-generation Camaros, Corvettes, modern Silverados, and Trailblazers. The straightforward installation process involves simply removing the old coil pack and inserting the D585 into the same cavity, making it a trusted choice for both technicians and DIY builders.
