LT Engine Series Conversion Kits

These engine kits have been designed for the new LT Series of engines that GM has been producing since 2014. They work with the LT1 and  LT4 6.2 liter Corvette and crate engines as well as the L83 5.3 and L86 6.2 truck engines. They are a bolt-in design with frame brackets that replace the originals and include polyurethane bushings that have a lifetime warranty. These kits position the engine so there is no steering interference, and have crossmembers that support all late model transmissions while maintaining proper drive-line angles. They provide clearance for the factory AC box, power brake booster, and aftermarket suspension components. The following combined parts offer an easy, strong, and clean installation of your LT engine.
