- See our LS/LT Crankshaft and Flexplate guide to determine where to place your crankshaft hub adapter
- Made in Wichita, Kansas from USA produced steel
- Compatible with all LS and LT series engines Gen 3, 4, 5 (except 99-00' 6.0L does not require this.)
- Includes: 1 adapter ring (inserts into rear of crankshaft)
***if installing a 6.0L engine from a 1999 or 2000 model then this part is not required. All other engines and years must use a crank adapter for any transmission that did not come factory behind an LS engine. Also a flex plate will be required due to the bolt pattern being different (use 551356, 551346, or re-drill your flex plate for the correct torque converter pattern)
