LT Engine Series

These kits are made specifically for each model car or truck and with the new LT Series engine.

No "universal" parts here. Every component was developed on actual project vehicles to ensure optimum placement and fit.

LT Engine Series Conversion Kits

In 2014 GM introduced the Gen 5 LT-series engines - representing a major redesign of the Gen 3 and 4 LS-series. With high-tech features like direct fuel injection the LT-series is setting new standards in power and efficiency. Once again Muscle Rods is leading the industry by developing kits to install the Gen 5 LT engines into your classic vehicles. The kits include new mounts and frame brackets that replace the originals, which means your LT engine will bolt in place no matter what type of engine was originally installed in the vehicle. Extensive R&D went into the engine placement resulting in great fit of all other components. Each kit includes a trans crossmember that maintains the proper drive-line angle and we support all late-model transmissions. The engine position provides clearance for the factory AC box, power brake booster, steering linkage and aftermarket suspension components. There is simply no other conversion kit on the market that offers such an easy, strong, and clean installation of your LT engine.

Our oil pans use OEM filters in the original location - no remote filters are needed. The billet front section has integrated pickup tube and o-ring like the originals. The 3/8" flange maintains proper rigidity. GM recommends using Permatex Ultra Grey Rigid High-Torque RTV Silicone to seal without a gasket.

LT front accessory brackets

We are also in development of LT front accessory bracket kits. The kits that have high mount AC compressor and also a power steering pump to use with traditional steering boxes. The OE brackets do not have power steering pumps because all of the cars and trucks that get LT engines from the factory have electric assist rack and pinion steering.
