Lead Time - All LS PCM conversion kits have a lead time estimate of 2-3+ weeks.
The Torqhead Corvette Essentials Kit gives you all the core components needed to modernize your 1994–1996 C4 LT1/LT4 Corvette with LS Gen 3 PCM control while keeping your factory LCD cluster and controls functional. This package is perfect for those who already have or want to source their own ignition coils, brackets, coil harness, and plug wires.
Now featuring the Gen 2 LCD/CCM Controller (Aug 2024), the Essentials Kit allows your factory gauges to remain active and, when equipped, displays enhanced parameters such as intake air temp, MAP, RPM, ignition advance, and commanded AFR. The PCM mounts in the factory location using the included C4 bracket, while our billet crank hub, sensors, and 24xLink technology deliver a clean, reliable, and performance-proven install.
