8L90E Transmission Mount Adapter for LS and LT Engines
When you mate an 8L90E transmission with an LS or LT engine you often find yourself battling misaligned mounts and custom adaptations. This 8L90E Transmission Mount Adapter lets both 8L90E and 10L90E tailshaft housings bolt straight to standard transmission mounts without spacers. Precision CNC machining from aircraft grade aluminum ensures the unit sits at factory specified angles and preserves driveshaft alignment for consistent torque delivery. Finally it matches GM LS and LT block patterns, fits off the shelf crossmembers and ships complete with all mounting hardware to remove guesswork.
Precision CNC Machining for Factory Spec Alignment
The adapter is CNC machined from aircraft grade aluminum to hold the transmission at exact angles specified in factory settings. This precision ensures that the driveshaft remains aligned across all operating conditions, which reduces vibration and eliminates undue stress on universal joints and splines. Consistent alignment also preserves power delivery responsiveness and helps prevent premature wear on related components. Builders will notice a smooth feel under both rapid acceleration and sustained loads as a result of this engineered accuracy. It also precisely mirrors the bolt pattern of GM LS and LT engine blocks, ensuring seamless mating without additional shims or spacers.
Aircraft Grade Aluminum Construction for Stress Resistance
Constructed from a premium grade aluminum alloy, this adapter offers an optimal strength to weight ratio that withstands high torque loads without adding unnecessary mass to the drivetrain. The corrosion resistant nature of the material ensures long term durability in a range of environments, from daily driving to track competition. By combining a robust design with material resilience, the unit resists deformation and maintains its performance even under repeated heat cycles. The metal also conducts heat away from high friction zones, helping to preserve material integrity during extended runs. Owners benefit from reliable support and reduced likelihood of fatigue or cracking over time.
Crossmember Compatible Design for Streamlined Installation
Engineered to match standard transmission mount locations, the adapter integrates directly with crossmembers without requiring spacers or custom brackets. This eliminates guess work and complex fabrication steps during installation, allowing builders to secure the transmission using existing mounting hardware. The result is a faster setup process that cuts down labor and reduces the chance of fitment errors. Whether working in a garage or on the track, installers will appreciate the plug and play nature of the design. The adapter also retains factory driveshaft length and engine setback to maintain original vehicle dynamics.
Complete Mounting Hardware for Accurate Assembly
All necessary screws and fasteners are provided with the adapter to meet the specific thread pitches and torque values of both the 8L90E and 10L90E tailshaft housings. This eliminates the need to source compatible parts and ensures that the clamp load remains consistent across thousands of miles of operation. Clear instructions accompany the kit to guide correct torque application with basic hand tools, preventing common mistakes that can lead to loosening or misalignment. Each fastener is precision matched to thread size and material thickness for consistent clamp load across thousands of cycles. This all inclusive approach offers peace of mind for builders targeting both street and track use.
Engineered to ensure precise alignment and dependable performance in every LS or LT application.
