When installing a Th350, Th400, Powerglide behind a LS engine while using a curved flywheel you'll need this adapter spacer. The spacer will center the nose of the converter to the curved flexplate.
- Perfect for LS Swaps: Enables the proper flexplate-to-crankshaft spacing required when pairing a GM LS engine with a TH350, TH400, or 700R4 transmission in swap applications.
- Accurate Crankshaft Alignment: Corrects the distance between the crankshaft flange and the flexplate to ensure proper input engagement without excessive preload or misalignment.
- Wide Engine Compatibility: Designed to work with popular GM LS engines, including 4.8L, 5.3L, 5.7L (LS1, LS6), 6.0L (LQ4, LS2), 6.2L (LS3), and 7.0L (LS7) platforms.
- Durable Steel Construction: Machined from high-strength steel to provide long-lasting durability, even under high-load or performance driving conditions.
- Hassle-Free Installation: No fabrication or cutting needed. Simply install the spacer between the crankshaft and flexplate when using the factory curved LS flexplate.
