Jeepspeed Crate Race Motor (4.0L)

Race proven! 

When you purchase a Jeepspeed Crate Race Engine you will receive the highest quality engine available. We maintain ISO/TS16949 Certification, which is the highest level offered. Each engine is hand assembled by our professional craftsmen using the highest quality equipment, process and parts available.  The initial process begins with the engine being completely disassembled and cleaned via baking, blasting and washing. Then the block, cylinder head, crankshaft and connecting rods are re-machined to conform to the original manufacturer's specifications. Once these processes are completed, numerous tests are performed to verify sizes, finishes, and part integrity. The engine is then re-assembled using new pistons, rings, bearings, timing components, oil pump, and gaskets. Finally, the engine is tested again under its own power. This is called POWER TEST. This is to verify compression, oil flow and pressure.
