Gen III / LS-Series Engine Mount Kit

The Advance Adapters GM Gen III Vortec Engine into Jeep TJ Mount Kit is a weld-in solution engineered for integrating GM Gen III / LS-Series V8 engines into Jeep TJ Wranglers manufactured between 1997 and 2008. This kit facilitates the simultaneous installation of the engine and compatible automatic transmissions such as the TH350, 700R, 4L60, and 4L60E, making it an excellent choice for GM automatic swaps. The complete kit includes all necessary components for a robust installation: custom weld-in frame perches, genuine stock GM engine rubber mount cushions, and all required fastening hardware. Comprehensive installation instructions are also provided to guide you through the process. It is important to note that when retaining the stock AX15 or NV3550 transmission, the transmission must be moved forward to properly couple with the engine. This ensures optimal drivetrain alignment and function after the swap.
