8L90E Transmission Mount Adapter for LS and LT Engine Swaps
Installing a Gen V 8L90E transmission behind an LS or LT engine often means wrestling with misaligned tailshaft flanges and complex fitment work. The 8L90E Transmission Mount Adapter secures both 8L90E and 10L90E tailshaft housings directly to factory crossmember points with exact CNC tolerances to keep driveshaft alignment within OE specifications. By matching GM mounting patterns and removing the need for shims or extra brackets, this adapter streamlines installation without chassis modifications or guesswork. Installers will appreciate that all required hardware is included and that the aluminum construction resists corrosion under high torque loads, ensuring reliable service life across varied driving conditions.
Precision CNC Machining Ensures Factory Driveshaft Alignment
The adapter is produced with computer numeric control machining to hold 8L90E and 10L90E tailshaft housings at exact OEM angles. By maintaining driveshaft alignment within tight tolerances, vibration is minimized and joint wear is reduced during both steady cruising and rapid throttle transitions. Accurate positioning prevents premature spline and bearing fatigue, preserving smooth power delivery in high torque applications. Installers benefit from an exact bolt pattern match to LS and LT engine blocks, removing the need for trial fitting or shims and saving valuable workshop time.
6061 T6 Aluminum Construction Delivers Rigidity and Corrosion Resistance
Manufactured from premium 6061 T6 billet aluminum, this adapter offers an excellent strength to weight ratio that resists deformation under heavy loads. Its innate corrosion resistance maintains structural integrity in wet or dusty environments, ensuring reliable performance over extended service intervals. The material’s thermal conductivity around high friction zones helps dissipate heat and reduce fatigue in areas exposed to continuous torque. Users will notice that the adapter holds its geometry under aggressive acceleration or towing, preserving alignment and part life.
Direct Fit to Factory Crossmember Simplifies Installation
Designed to mirror GM mounting patterns for LS and LT engines, the adapter bolts directly to existing transmission crossmembers without extra brackets or shims. This direct fit maintains factory driveshaft length and engine setback, preserving the vehicle’s designed handling characteristics and reducing the need for custom fabrication. Builders can reuse stock hardware and standard tools, cutting mockup time and complexity. The streamlined installation process allows focus on wiring and plumbing instead of fitment issues, delivering consistent results across various swap platforms.
Included Fastener Set Optimizes Assembly Reliability
The kit includes mounting screws that are precisely matched to thread pitches and housing wall thickness for both 8L90E and 10L90E cases. Each fastener meets specified torque guidelines, reducing the chance of loosening under vibration and load cycles. Detailed instructions outline the correct sequence for tightening with common hand tools, preventing misalignment and overtightening concerns. By supplying hardware engineered for this application, the adapter eliminates uncertainty over compatible parts and ensures a dependable installation from day one.
Trust in the precision fit and durable construction of this adapter for reliable driveshaft alignment.
