TSP Gen 5 LT1, LT4, & L86 376 CID Balanced Rotating Assembly

Texas Speed & Performance rotating assemblies offer the best durability with the best pricing available! Bearings are not included in the base price but can be added to your rotating assembly package. Give us a call, and we will be happy to spec out a rotating assembly that will match your needs!

If you select a GM crankshaft, you will have to run the GM main bearings.  The chamfer is different on the journals for a GM crank vs. all of the aftermarket cranks, so the narrowed aftermarket bearings will not work with the GM crankshafts.  You WILL use the Clevite connecting rod bearings since you will be running aftermarket connecting rods.  Please make the appropriate bearing selection for the crankshaft you're selecting.

**Clevite does not currently offer a gen 5 LT1-specific main bearing set. The Clevite main bearing set used for all of the LSx engines will work, but it will require minor modification to the engine block for the center thrust bearing. If this could be an issue with your machine shop, please verify that they can perform the work properly! This is one of the things that will automatically be done if you purchase your engine from Texas Speed & Performance!
