Get Your 1958-1964 Chevy Impala B-Body LS-Ready with MuscleRods

Achieve precise chassis geometry for your LS swap with tailored mounts and F-Body oil pan compatibility to eliminate transmission tunnel modifications. MuscleRods Engine Swap Kit delivers a seamless fit to your 1958-1964 Chevy Impala B-Body with T56, 4L60E or 4L80E transmission compatibility and all hardware made in the USA for dependable, vibration free driving.

MuscleRods LS Engine Swap Kit for 1958-1964 Chevy Impala B-Body

Installing an LS motor into a 1958-1964 Chevy Impala can be complicated by misaligned engine rails and time-consuming bracket fabrication. This conversion kit secures your LS engine and transmission crossmember directly to the factory frame rails and removes the need for major tunnel modifications or aftermarket brackets. Matching the driveline angle to factory specification prevents excessive vibration feedback through the chassis and preserves universal joint and bearing life. Support for T56, 4L60E and 4L80E transmissions and compatibility with common LS oil pan designs let you focus on wiring and plumbing instead of custom clearancing.

Precision Drivetrain Geometry for Smooth LS Integration

The conversion kit holds your LS engine and transmission at factory specified angles to minimize driveshaft windup and vibration feedback. By preserving correct drivetrain geometry, it also reduces wear on universal joints and transmission bearings, extending component life under load. Drivers will notice crisper shifts and a more refined feel on both city streets and open roads. This attention to angle alignment makes a direct impact on long term reliability and ride comfort.

Preformed Mounts Simplify Impala Engine Bay Installation

Each motor mount and frame bracket is laser cut and welded to bolt directly into the factory frame rails of a 1958 to 1964 Chevy Impala without cutting or welding the floor structure. This preformed approach eliminates hours of mockup and custom bracket fabrication, letting you focus on wiring and plumbing tasks instead of metal shaping. The snug fit under the hood also ensures proper clearance with the factory firewall and steering components. Builders appreciate how the system snaps into place with minimal trial and error.

Versatile Transmission and Engine Pairing

Support for T56, 4L60E and 4L80E transmissions gives you freedom to choose your preferred gearbox without major modifications. The crossmember and mount pack accept common bolt patterns while keeping the driveline angle within factory tolerances. Compatibility extends to most Gen III and Gen IV LS engines when used with a recommended oil pan design for hood clearance. This flexibility reduces the need for adapter plates or custom spacers when swapping popular powerplants into the Impala frame.

United States Production Delivers Consistent Quality

All components are manufactured in the United States under strict quality control to ensure precise bracket geometry and repeatable fitment. Domestic production enables tighter tolerances and faster feedback loops with fabricators, resulting in durable brackets that resist fatigue under daily driving or spirited runs. By sourcing locally you also benefit from a stable supply chain for replacement parts and future upgrades. The end result is a dependable mounting solution you can trust on every drive.
