Complete MuscleRods LT Engine Swap Kit for 1991-1996 B-Body Impala/Caprice
If you're swapping an LT engine into a 1991-1996 Chevy Impala or Caprice chassis the 1991-1996 B-Body LT Conversion Kit addresses the tight clearances and misaligned engine mounts that often stall B-Body projects. It preserves correct drivetrain geometry by aligning the transmission tailshaft and pinion angle within factory tolerance to keep vibration under control and maintain cabin comfort. MuscleRods engineered the engine mount brackets and transmission crossmember to GM mounting points for seamless plug and play integration with 4L60E and 4L80E setups.
Precision Fit Components for Seamless LT Engine Integration
This kit delivers engine and frame mounts plus a transmission crossmember machined to exact GM mounting points, eliminating hours of trial alignment. Each bracket is laser cut and jig welded to maintain consistent locating surfaces so the Gen V LT engine drops directly into the B-Body frame. By preserving firewall and chassis clearances, the installation requires no tunnel trimming or custom fabrication, allowing technicians and enthusiasts to secure the engine and transmission with confidence and speed.
Maintaining Drivetrain Angles to Minimize Vibration
Retaining factory geometry is critical to prevent harmonic imbalance and harsh driveline vibration. The kit holds the pinion angle and tailshaft alignment within stock tolerances, eliminating the need for shims or spacers after assembly. The result is a smoother ride with reduced driveline windup under acceleration, ensuring cabin comfort during both city driving and high-speed cruising.
Compatibility with Extended Sump Oil Pan for Reliable Lubrication
High-output LT engines demand consistent oil control even under lateral G-forces, and this package clears deeper sump oil pans without interference. The crossmember and frame mounts are positioned to preserve steering shaft geometry and structural stiffness while accommodating an extended pan profile. Builders benefit from direct compatibility that keeps the oil pickup submerged during hard cornering, protecting bearings and prolonging engine life.
American Made Construction for Consistent Quality and Durability
All components are proudly manufactured in the USA from high-grade steel with rigorous quality checks at every stage. The robust material selection and precise fabrication methods deliver long-term reliability in demanding conditions. This commitment to domestic production ensures each kit meets stringent standards for strength and fit, giving users confidence in their investment.
