Dominator EFI Kit - LS2/LS3 Late Truck

The Dominator EFI Kit - LS2/LS3 Late Truck is a complete, bolt-on fuel injection system designed for late-model LS-platform trucks that require modern EFI control without the complexity of a full engine rebuild. Manufactured by Holley, a leader in performance fuel systems, this kit offers the reliability of sequential fuel injection along with the tuning flexibility that LS enthusiasts seek.

This system features a self-contained ECU that is factory pre-calibrated for LS2 and LS3 engines, simplifying installation and reducing tuning time. With pre-mapped injector staging, spark timing, and idle control, the kit is designed for optimized combustion efficiency and emission compliance. The compact design, weighing 12.7 lbs and measuring 15.3 × 9.9 × 26.8 inches, allows for easy fitment in late-truck engine bays.

Truck builders and LS swappers will find this kit particularly beneficial when installing engines into vehicles that originally lacked modern EFI architecture. It bridges the gap between raw LS power and dependable daily driving, making it an ideal choice for those upgrading from carbureted systems or transitioning crate motors into late-truck platforms.
