Product Description
Michigan Motorsports 8-Bolt Crankshaft Flange Spacer Adapter with Bolts
Fits 2009–2015 LSA Engines & 2014–Newer Gen V LT Engines | Includes Spacer + 8 High-Strength Bolts
This Michigan Motorsports 8-Bolt Crankshaft Flange Spacer Adapter allows you to run an earlier non-LS/LT torque converter behind your LSA or Gen V LT-series engine. Whether you're performing a swap or adapting older GM transmissions, this spacer ensures proper flexplate spacing, torque converter alignment, and full snout engagement. Precision-machined from high-quality steel with a black oxide finish, it delivers the durability required for high-performance builds.
Key Features
- Perfect Converter Adaptation: Allows earlier non-LS/LT torque converters to be used with LSA or Gen V LT engines, solving spacing and alignment issues during swaps.
- Correct Flexplate Spacing: With flat flexplates, the spacer installs between the crankshaft and flexplate. With dished flexplates, it installs between the flexplate and torque converter for proper snout engagement.
- Premium Construction: CNC-machined from high-quality steel and finished with durable black oxide for long-term corrosion resistance and strength.
- Complete Installation Hardware: Includes 8 extended-length, high-strength flexplate bolts required for proper installation and torque retention.
- Transmission Compatibility: Designed for TH350, TH400, 700R4, 4L60, 4L60E, 4L80, 4L80E, and 4L85E transmissions commonly used in swap applications.
Key Fitments
- Engines: LSA (2009–2015) and 2014–Newer Gen V LT engines including LT1, LT4, L83, L82, L84, L86, L87, L8B, L8T in 5.3L, 6.2L, and 6.6L configurations.
- Platforms: Compatible with GM performance cars, trucks, SUVs, and all LS/LT swap platforms utilizing earlier GM transmissions such as TH350, TH400, 700R4, 4L60/4L60E, 4L80/4L80E, and 4L85E.
- Notes: Includes required longer flexplate bolts. Torque bolts to 85 ft-lbs using a criss-cross pattern with blue threadlocker. Not required when using LS/LT-specific torque converters with dished flexplates.
