Simplify Your 1958-1964 Impala B-Body LS Build with MuscleRods

Engineered to eliminate drivetrain misalignment on your 1958 to 1964 Chevy Impala B Body, MuscleRods Engine Swap Kit features precision engineered mounts, integrated F Body oil pan clearance and correct drivetrain angle for seamless LS installation. It delivers a snug, direct fit for T56, 4L60E or 4L80E transmissions without transmission tunnel modifications, reduces install time and provides a vibration-free driving experience with premium hardware made in the USA.

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

Fitting a modern LS motor under the hood of a 1958 to 1964 Chevy Impala on a B Body frame often stalls at the mounting stage; the 1958 to 1964 B Body LS Conversion Kit secures the engine and transmission crossmember to the factory frame rails without altering the tunnel. It holds the powertrain at factory specified angles to prevent excessive vibration and protect universal joints and transmission bearings for a refined ride. MuscleRods built each laser cut bracket and mount pack to bolt directly into the original rails while offering support for T56, 4L60E and 4L80E transmissions. By integrating with common LS oil pan designs it also ensures proper hood clearance and simplifies plumbing and wiring tasks so builders can move on to final assembly without trimming inner structure.

Precision Drivetrain Geometry for LS Powertrains

The conversion kit holds the LS engine and transmission at factory specified angles to minimize driveshaft twist and vibration feedback through the chassis. By preserving correct alignment, universal joint wear and bearing stress are reduced under load, extending service life of critical parts. It uses laser cut brackets and calibrated spacers to achieve these angles without complex trial fitting, so builders avoid multiple mockup sessions. This precision pays off in crisper shift feel and a refined ride, enhancing both low speed maneuvering and open road cruising.

Streamlined Frame Rail Integration with Laser Cut Brackets

The motor mounts and frame brackets are laser cut from high strength steel and welded to exacting tolerances so they bolt directly into the original side rails of the 1958-1964 B Body frame. This approach eliminates hours of metal shaping and measurement checks common with custom bracket fabrication. Because the crossmember aligns with the stock transmission tunnel, installers avoid trimming or modifying the floor structure for clearance. The preformed components also position the LS oil pan under standard hood profiles used by F Body engines, simplifying plumbing and wiring runs. Every kit includes a hardware pack with grade 8 fasteners sized for each mount, ensuring reliable joint integrity.

Broad Transmission and Engine Compatibility for Impala Swaps

With built in support for T56, 4L60E and 4L80E transmissions, this kit offers flexibility for both performance builds and stock feel installations. It accepts common bolt patterns on most third and fourth generation LS engines when paired with a recommended style oil pan, removing the need for adapter plates in many cases. By matching driveline geometry within factory tolerances, the system maintains efficient power flow and reduces vibration regardless of gearbox choice. Swap builders can pair popular GM small block or truck style LS powerplants with confidence, backed by a solution engineered specifically for the Chevy Impala B Body platform.
