Smooth LS Install for 1991-1996 Caprice Impala by MuscleRods

Engineered for precise fit in your B-Body, the LS Conversion Kit delivers smooth, vibration free performance thanks to precision mounts and optimized drivetrain angle. Eliminating transmission tunnel modifications and supporting T56, 4L60E or 4L80E transmissions plus LH8 oil pan options for extra ground clearance, MuscleRods streamlines installation while ensuring proven USA made durability.

MuscleRods LS Engine Swap Kit for 1991-1996 Caprice and 1994-1996 Impala B-Body

If you are planning to install an LS in your 1991 to 1996 Caprice or Impala, this kit addresses the common challenge of misaligned mounts and tight clearances by providing mounts and a crossmember that bolt directly to the factory frame rails. The components preserve the factory engine tilt and eliminate transmission tunnel mods for T56, 4L60E, or 4L80E gearboxes. Installation is further simplified with support for both standard and LH8 oil pans and a complete hardware pack of USA-made brackets and fasteners that ensures a straightforward swap even for those new to LS conversions.

Maintaining Factory Engine Tilt for Smooth Power Delivery

By preserving the original engine tilt, this kit keeps the driveshaft and transmission in precise alignment, reducing vibration and NVH in the cabin. Correct geometry under load minimizes stress on universal joints and bearings, extending their service life and lowering maintenance costs. Whether accelerating from a stoplight or cruising on the highway, the balanced drivetrain orientation delivers predictable throttle response and a refined driving experience. This attention to factory angles ensures that your LS swap feels as natural as the original installation.

Direct Fit Transmission Crossmember for Quick Installation

The precision-engineered crossmember bolts directly to the 1991–1996 B-Body frame rails, eliminating the need to reshape or cut into the transmission tunnel for T56, 4L60E, or 4L80E gearboxes. Fixed mounting points guarantee consistent transmission height, making driveshaft matching straightforward and preventing binding under full articulation. Installers benefit from reduced mock-up time and fewer measurement checks, so even those with limited fabrication experience achieve factory-level results. This streamlined approach gets your LS project back on the road faster and with minimal guesswork.

Oil Pan Flexibility for Ride Height and Clearance

The kit supports both high-clearance and LH8 oil pans, allowing you to tailor underbody clearance without modifying mounts or brackets. Off-road enthusiasts gain extra room for rough terrain, while show-car builders can opt for a low-profile pan that compliments a dropped stance. Combined with the correct intake design for hood clearance, the system maintains optimal oil capacity and cooling efficiency during high-G cornering. This versatility lets you adapt the swap to diverse use cases without compromising engine protection.

Comprehensive USA-Made Hardware Set for Hassle Free Assembly

All necessary mounting brackets, motor mounts, crossmember hardware and a polyurethane transmission mount arrive together in one kit, each component laser-cut or CNC-formed in the USA to exact tolerances. The polyurethane mount absorbs shock and reduces drivetrain harshness, while precise bracket fitment prevents unwanted flex under torque. By consolidating every piece into a single package, this kit eliminates part-hunting and coordination headaches, delivering a cohesive solution for Caprice and Impala B-Bodies. Even novice builders can achieve a professional-grade installation with confidence.
