Your Foundation for a 1991-1996 Chevy Caprice/Impala LS Build with MuscleRods

Achieve a smooth, vibration free LS swap in your 1991-1996 B-Body thanks to precision engineered mounts and direct fit hardware designed for Caprice and Impala models. By eliminating transmission tunnel modifications and offering compatibility with T56, 4L60E and 4L80E transmissions along with LH8 oil pan options for extra ground clearance, this MuscleRods kit delivers a faster hassle free install and proven USA made durability.

MuscleRods LS Engine Swap Kit for 1991-1996 B-Body Caprice and Impala

Aiming to harness modern LS torque in a 1991-1996 B-Body often uncovers misaligned engine mounts and clearance hurdles. MuscleRods engineered this kit with engine mounts and a transmission crossmember that bolt directly to the original frame rails. Installation requires no modification to the transmission tunnel for T56, 4L60E, and 4L80E gearboxes and supports both high clearance or LH8 oil pan options. By preserving correct drivetrain angles and providing a direct fit for Caprice and Impala models, it cuts vibration and keeps even novice builders moving forward.

Optimal Drivetrain Alignment for Vibration Free Operation

The conversion kit maintains the factory engine tilt to deliver smooth power delivery without the shakes and buzz common to misaligned swaps. By preserving the original frame-rail mounting points, it ensures the driveshaft and transmission remain in precise alignment under load. This attention to geometry not only reduces noise and harshness in the cabin but also extends the life of universal joints and bearings by minimizing side loads. Whether forging through city streets or opening the throttle on the highway, you'll appreciate the refined ride quality that correct drivetrain angles provide.

Direct Fit Transmission Crossmember for Simplified Integration

The precision-engineered crossmember bolts straight to the B-Body frame rails, eliminating the need to reshape or cut into the transmission tunnel for T56, 4L60E, or 4L80E gearboxes. Its fixed mounting points guarantee consistent transmission height, which simplifies driveshaft matching and prevents binding under full articulation. Installers save hours of mock-up and testing, allowing even those with limited fabrication experience to achieve professional results. The outcome is a seamless fit that respects the car's unmodified interior while delivering modern gearbox performance.

Oil Pan Versatility for Ground Clearance and Fitment Control

Whether you require extra underbody room for rough roads or prefer a low-profile setup, the kit accommodates both high-clearance and LH8 oil pans. This dual-pan compatibility means you can specify the pan shape that suits your vehicle's use case-off-road excursions or show-car stance-without reengineering the mounts. Coupled with the correct intake for B-Body hood clearance, the system ensures adequate oil capacity and cooling efficiency under high-G cornering. The result is a tailored installation that adapts to your ride height and performance demands.

Complete Mounting Hardware Package for Issue Free Installation

Every necessary component arrives in one box, from two engine mounts and matching frame brackets to the transmission crossmember, crossmember brackets, secondary driver-side bracket, polyurethane transmission mount, and a comprehensive hardware pack. Each piece is laser-cut or CNC-formed in the USA to exact tolerances, ensuring repeatable fitment across all 1991-1996 Caprice and 1994-1996 Impala models. The polyurethane transmission mount dampens drivetrain shock, while the robust brackets anchor the engine and gearbox with minimal flex. By integrating these components into a unified system, the kit reduces part-hunting and removes guesswork, making for a headache-free swap process.
