Frame-Sparing 8L90E Adapter for LS and LT Setups

Maximize installation speed and reliability in LS and LT setups with a robust adapter built from high grade aluminum that mounts 8L90E and 10L90E transmissions to standard crossmembers. Its user focused design eliminates complex frame alterations and delivers smooth high torque performance for dependable long term operation.

8L90E Transmission Mount Adapter for LS and LT Engines

When fitting an 8L90E behind an LS or LT engine the factory mounts rarely line up without heavy modification. This 8L90E Transmission Mount Adapter addresses that gap by allowing both 8L90E and 10L90E tailshaft housings to bolt directly to standard transmission mounts. Made from CNC machined aluminum it stands up to sustained torque while keeping installation simple with no cutting or welding required. The adapter joins with compatible transmission crossmembers and installs in minutes using basic hand tools for a secure and dependable setup.

Exact Transmission Positioning for LS LT Setups

The 8L90E Transmission Mount Adapter delivers precise alignment between 8L90E or 10L90E tailshaft housings and factory mounting points on LS and LT engines. By maintaining correct geometry, it minimizes stress on driveshaft splines and universal joints, resulting in smoother power transfer and less vibration under load. This precision fit also helps prevent premature wear on drivetrain components by keeping torsional forces evenly distributed throughout the system.

High Grade Aluminum Design for Torque Resistance

Constructed from premium grade aluminum, the adapter balances exceptional strength with minimal added mass. The alloy's natural corrosion resistance and thermal stability stand up to sustained engine heat and repeated torque spikes without deforming. Its rigid structure ensures the connection between transmission and chassis remains rock solid, delivering lasting reliability in demanding swap applications.

Installation That Requires No Cutting or Welding

With this adapter, you can complete the installation in minutes using basic hand tools-no frame modifications or special fabrication are needed. It integrates directly with compatible transmission crossmembers, and the supplied hardware locks the unit in place for a secure fit. This simplified process reduces labor time and eliminates common fitment headaches, making it ideal for both first-time builders and seasoned pros.

Engineered for precise alignment and lasting performance in LS and LT swap projects.
