Get Your 1991-1996 Chevy Caprice Impala LS Swap Ready with MuscleRods

Delivering direct fit and optimized driveline angle for 1991-1996 Chevy Caprice and 1994-1996 Impala, the MuscleRods 1991-1996 B-Body LS Conversion Kit ensures vibration-free power transfer without transmission tunnel modifications. Proudly engineered in the USA from durable steel, it includes precision mounts, weld tabs and all hardware for T56, 4L60E or 4L80E installations while supporting LH8 oil pan options and offering extra ground clearance.

Complete MuscleRods LS Engine Swap Kit for 1991-1996 Chevy Caprice/Impala B-Body

If you are fitting an LS powerplant into a B-Body Caprice or Impala from 1991 through 1996 the 1991-1996 B-Body LS Conversion Kit offers a turnkey approach to maintain factory tilt and eliminate vibration. It uses precision machined steel mounts and a bolt on crossmember that aligns LS engines with T56 4L60E and 4L80E transmissions without altering the tunnel. Compatibility with both standard and LH8 oil pans gives extra underbody clearance while exact centerline alignment protects universal joints and transmission bearings from stress under load. Backed by MuscleRods this Engine Swap Kit includes all brackets and hardware for a streamlined installation.

Adaptive Fit for Diverse LS Engine Configurations

This kit accommodates most Gen III and IV LS engines, such as LS1, LS2, LS3, 5.3L and 6.0L powerplants, when paired with a high clearance or cast aluminum retro style oil pan and the correct intake for hood clearance. By engineering each mount interface to match both standard and LH8 pan profiles, the system preserves underbody space without compromising pickup placement for reliable oil scavenging. This versatility means builders can choose the LS variant that meets their performance goals without fabricating custom brackets or altering the frame rail geometry. The adaptable design also maintains the factory driveline angle, ensuring smooth power delivery and extending service life of universal joints and transmission bearings.

Preserving Chassis Integrity with Non Intrusive Mounting

The bolt on crossmember and matching frame brackets attach directly to the original 1991–1996 Caprice and Impala rails, eliminating the need for transmission tunnel modification. By retaining the stock floor structure and avoiding cuts or patches, coolant and brake lines remain undisturbed, reducing the risk of leaks or corrosion over time. Precision machining guarantees that the engine and transmission align to factory specifications from the first fit, removing trial and error trimming steps. Installers experience a straightforward process that minimizes downtime, tooling requirements and potential damage to the original chassis. This approach also simplifies future restoration or powertrain swaps by preserving the factory mounting points.

Resilient Steel Construction and Polyurethane Vibration Control

All motor mounts, frame brackets and the crossmember are fabricated from high grade American steel and CNC formed to exact tolerances for uniform strength across mounting surfaces. Weld joints are carefully executed to maintain rigidity under repeated torque loads, ensuring consistent driveline angle and centerline alignment throughout suspension travel. The included polyurethane transmission mount cushions driveline shock and dampens gear rattle, reducing noise under acceleration and during light throttle modulation. By combining durable steel components with targeted vibration control, the system enhances driver comfort while protecting universal joints and transmission bearings from premature wear.
