8L90E Transmission Mount Adapter for LS and LT Swaps
The 8L90E Transmission Mount Adapter tackles one of the biggest obstacles in LS and LT engine swaps by allowing direct bolt up of 8L90E and 10L90E tailshaft housings to standard mounts. Crafted from precision CNC billet aluminum, it positions the transmission at factory angles to maintain driveshaft alignment under all driving conditions. Installation is simplified thanks to compatibility with common crossmembers and inclusion of all required fasteners. Builders will appreciate reduced mockup time and consistent torque delivery without extra spacers or shims.
Precision CNC Machining for Exact Driveshaft Alignment
The 8L90E Transmission Mount Adapter is machined from billet aluminum using precision CNC equipment to hold the transmission at factory specified angles. This exacting process ensures driveshaft alignment is preserved under both steady cruising and rapid throttle changes, reducing vibration and stress on universal joints. By maintaining alignment within tight tolerances, power delivery remains smooth and consistent, preventing premature wear on splines and bearings. Builders benefit from predictable performance as the adapter mirrors the bolt pattern of LS and LT engine blocks without the need for shims. The result is reliable driveline geometry that safeguards related components over thousands of miles of operation.
High Grade Aluminum Construction for Torque Resilience
Crafted from aircraft grade billet aluminum, this adapter offers an exceptional strength to weight ratio that stands up to the torsional forces of large displacement V8 powerplants. The material's natural corrosion resistance ensures the adapter retains its integrity in varied environments, from humid street conditions to dusty off road trails. Its ability to dissipate heat away from high friction zones reduces thermal stress during extended use, helping to avoid metal fatigue. The robust design resists deformation under high torque loads, delivering consistent support throughout hard launches and sustained pulls. Owners can rely on this durable solution to maintain alignment and structural stability in demanding applications.
Direct Bolt Up Design for Simplified Crossmember Integration
Engineered to work with 8L90E and 10L90E tailshaft housings, the adapter bolts directly to traditional transmission mounts without the need for spacers or custom brackets. It matches the mounting pattern on GM LS and LT engine blocks, allowing installers to use existing crossmember mounting points and hardware. This plug in approach slashes mockup time by eliminating fabrication steps, so builders can focus on wiring and plumbing rather than trial fitting. With the adapter in place, factory driveshaft length and engine setback remain unchanged, preserving original vehicle dynamics. Whether fitting into a muscle car or a classic pickup, installers will appreciate the straightforward, reliable fit.
Complete Fastener Kit for Accurate Torque Assembly
The adapter ships with a full set of mounting screws that are precisely matched to the thread pitches and material thicknesses of both the 8L90E and 10L90E housings. Each fastener meets specific torque values to ensure uniform clamp load across all attachment points, reducing the risk of loosening under vibration. Clear instructions guide correct torque application using common hand tools, preventing over tightening or misalignment during assembly. By providing hardware that is engineered for the application, the kit removes the guesswork of sourcing compatible parts. This all inclusive approach delivers peace of mind for builders aiming to achieve reliable performance on both street and track.
This adapter ensures precise fit and dependable performance for LS and LT engine swaps.
