Q&A

What's the difference between this and the standard LS Flexplate Adapter (81110)?
This spacer works with either a flat or dished flexplate, making it more versatile than TSP's standard LS Flexplate Adapter (SKU 81110), which requires a dished flexplate specifically. The two can generally be used in place of one another — choose based on which flexplate style your build uses.

What transmissions does this work with?
Pre-1997 GM automatic transmissions: TH350, TH400, 700R4, 4L60, 4L60E, and 4L85E.

Will this fit an LQ4 engine?
No — this spacer will not fit LQ4 engines.

Does this come with mounting hardware?
Yes — mounting hardware is included.

What's this spacer made of?
Steel.
