Like the LS platform, GM's Gen V LT engine family can be identified using the 8th digit of your VIN. This is the quickest and most reliable method when the original engine is still in the vehicle.
LT ENGINE VIN CODES (8TH DIGIT): G = LT1 (6.2L, Corvette/Camaro/Trucks) R = LT4 (6.2L supercharged, high-performance) S = LT2 (6.2L, C8 Corvette mid-engine)
TRUCK LT VARIANTS (8TH DIGIT): G = L82 (5.3L aluminum block, some truck applications) J = L87 (5.3L, newer truck variant) T = LT1 (6.2L truck, in certain year/model combinations)
Note: The truck LT variants share some VIN codes with car applications, and the exact code-to-engine mapping can vary by model year and vehicle line. The same 8th digit may point to different engines depending on whether you have a car or truck.
VIN DECODER RECOMMENDATION: For full confirmation, use a GM VIN decoder or contact us directly. We can look up the full build sheet for your VIN and confirm the exact engine.

IMPORTANT: The VIN reflects the factory-installed engine. If the vehicle has had an engine swap, the VIN code will not match the current engine. In that case, identify the engine visually using the casting number on the block.
