Complete MuscleRods LS Engine Swap Kit for Tri-Five Chevy
When installing an LS power plant into a Tri-Five Chevy, the 1955 through 1957 Chevy LS Conversion Kit tackles engine placement and driveline angle challenges in classic two-door Chevrolet models. Engineered by MuscleRods with precision frame mounts, engine mounts and a sturdy transmission crossmember, the kit accepts T56, 4L60E and 4L80E transmissions without altering the transmission tunnel. All components are made in the USA and configured to hold the correct driveline angle for a vibration free ride. Options for a high clearance oil pan or the LH8 design result in a hassle free installation that gets your build on the road fast.
Maintaining Precise Driveline Angle for Vibration-Free Operation
Achieving the correct driveline angle is critical when fitting an LS engine into a Tri-Five Chevy. The kit positions the engine and transmission at the factory recommended angle to minimize unwanted vibrations. By aligning the transmission output shaft with the rear axle pinion, the design ensures smooth power delivery under load. This alignment reduces stress on universal joints and extends the service life of related components. The result is a more comfortable ride and a lower likelihood of drivetrain noise or wear.
Comprehensive Compatibility with LS Engine Platforms and Transmissions
This conversion package supports a wide range of Gen III and Gen IV LS engines, including LS1, LS2 and LS3 variants, without requiring frame alterations. It accepts T56, 4L60E and 4L80E transmissions directly, so you avoid any modifications to the transmission tunnel. For applications that demand extra oil pan clearance, the kit works seamlessly with the LH8 GM oil pan and a low profile intake manifold to clear the stock hood opening. This versatility lets builders retain classic exterior lines while integrating modern powertrain technology.
American-Made Mounting Components for Robust Support
Every part in this conversion kit is manufactured in the United States to exacting standards, reflecting a dedication to quality and consistency. Precision frame brackets and engine mounts are formed from heavy-gauge steel to withstand the torque output of contemporary LS engines. A sturdy transmission crossmember paired with a polyurethane mount pack ensures reliable support under heavy acceleration. All necessary hardware-bolts, spacers and brackets-is included to streamline assembly and guarantee each mounting point meets the designed tolerances.
