Holley SE2-GMG-LSX-M G-Body Level LS Swap Essentials Kit Manual Transmission - 2

The Holley SE2-GMG-LSX-M is a Level 2 LS Swap Essentials Package designed for 1978–1988 GM G-Body vehicles equipped with a manual transmission (T-56, T-56 Magnum, or Tremec TKX). This bundled kit takes the guesswork out of sourcing the right components for an LS or LT engine swap, combining engine mounts, transmission mounts, and an LS-specific oil pan into a single, engineered solution that delivers factory-style fitment.

As a Level 2 package, this kit builds on the foundation of the Level 1 mount set by adding an LS-swap-specific oil pan, ensuring maximum crossmember clearance for guaranteed fitment in the G-Body chassis. All mounting geometry is designed in CAD to optimize driveline angles, reducing vibration and maximizing power transfer to the wheels.

Key Features:

• Complete Level 2 LS/LT swap mounting package for 1978–1988 GM G-Body platforms
• Compatible with T-56, T-56 Magnum, and Tremec TKX manual transmissions
• LS-swap oil pan included for maximum crossmember clearance and guaranteed fitment
• CAD-engineered mounts to optimize driveline angles and reduce drivetrain vibration

• Bundle savings compared to purchasing individual swap components separately

Holley's tiered Swap Essentials lineup allows builders to choose the level of completeness that fits their budget and build goals, with each higher level adding more hardware and greater savings. The SE2-GMG-LSX-M is the ideal starting point for builders who want a complete mount and oil pan solution for their G-Body LS swap with a manual gearbox.
