8L90E Transmission Mount Adapter for LS and LT Engine Swaps
The 8L90E Transmission Mount Adapter tackles the fitment headache when mating a Gen V transmission to LS and LT engine platforms. With a precision CNC design it bolts the 8L90E and 10L90E tailshaft housings directly to factory mounts without shims or extra brackets. It aligns the transmission at OE angles to preserve driveshaft alignment under load and minimize vibration throughout the driveline. Installers will value its compatibility with familiar crossmember mounting points and the inclusion of all required hardware, while the aluminum construction resists torque forces and environmental corrosion for reliable service life.
Precision CNC Machining for Exact Driveshaft Alignment
The 8L90E Transmission Mount Adapter is crafted through computer numeric control machining to hold 8L90E and 10L90E tailshaft housings at factory specified angles. By maintaining driveshaft alignment within tight tolerances, this adapter minimizes vibration and reduces stress on universal joints during both steady cruising and rapid throttle transitions. Accurate positioning prevents premature wear of splines and bearings, ensuring smooth power delivery over thousands of miles. Installers benefit from an exact bolt pattern match to LS and LT engine blocks, eliminating the need for trial fitting or shims. The result is a reliable driveline geometry that preserves vehicle dynamics under load.
Aircraft Grade Aluminum Construction for Lasting Durability
Manufactured from premium 6061 T6 billet aluminum, the adapter offers an ideal strength to weight ratio that stands up to the torsional forces of large displacement V8 powerplants. Its innate corrosion resistance maintains structural integrity in diverse conditions, from wet city streets to dusty off road terrain. The material's thermal conductivity helps dissipate heat around high friction zones, reducing metal fatigue during extended operation. With resistance to deformation under torque loads, the adapter retains precise alignment during aggressive acceleration and towing. This robust construction delivers long service life without compromising performance.
Plug and Play Integration with Factory Crossmembers
Designed to integrate seamlessly with common transmission crossmembers, the adapter bolts directly to traditional mounts without custom brackets or extra spacers. It mirrors GM's mounting pattern for LS and LT engines, allowing installers to reuse existing hardware and avoid fabrication work. By preserving factory driveshaft length and maintaining original engine setback, the adapter sustains the vehicle's designed handling characteristics. The simplified installation process cuts mockup time significantly, so builders can focus on wiring and plumbing rather than fitment issues. This straightforward approach ensures consistent results across a wide range of swap applications.
Engineered Fastener Kit for Consistent Assembly
Included mounting screws are precisely matched to the thread pitches and material thickness of both the 8L90E and 10L90E housings, ensuring uniform clamp load across all attachment points. Each fastener meets specified torque values, which reduces the likelihood of loosening under vibration and load. Detailed instructions guide installers through the correct torque sequence with common hand tools, preventing misalignment and over tightening. By supplying hardware optimized for this application, the kit removes the uncertainty of sourcing compatible parts. This all inclusive solution provides confidence and reliability from initial installation to high mileage use.
