Facilitate seamless integration between your Gen III/IV LS engine and earlier GM automatic transmissions with the Michigan Motorsports LS Crankshaft Adapter Flexplate Spacer. This precision-machined steel spacer ensures proper alignment and engagement between the crankshaft and torque converter, addressing the spacing discrepancies that arise when mating LS engines to transmissions like the TH350, TH400, 700R4, 4L60, 4L60E, 4L80, and 4L80E. The adapter is designed to be used either between the crankshaft and a flat flexplate or between a dished flexplate and the torque converter, depending on your specific setup. Its durable construction and black oxide finish provide corrosion resistance and longevity, making it an essential component for LS engine swaps and transmission conversions. Please note that the use of this spacer requires longer flexplate bolts; ARP Kit #244-2902 is recommended for optimal installation.

  • Ensures Proper Torque Converter Engagement: Corrects spacing issues when connecting LS engines to non-LS GM automatic transmissions, ensuring reliable power transfer.
  • Versatile Compatibility: Designed for use with TH350, TH400, 700R4, 4L60, 4L60E, 4L80, and 4L80E transmissions, making it ideal for a wide range of LS engine swap applications.
  • Durable Steel Construction: Manufactured from high-quality steel with a black oxide finish for enhanced strength and corrosion resistance.
  • Flexible Installation Options: Can be installed between the crankshaft and a flat flexplate or between a dished flexplate and the torque converter, depending on your specific setup.
  • Essential for LS Engine Swaps: Addresses common alignment issues in LS engine conversions, ensuring a smooth and reliable drivetrain integration.
