These do not come assembled. We can arrange to have the kit assembled before shipment for additional charge, however, this kit is designed for the customer who is planning to have the block assembled themselves.

This rotating assembly includes everything you will need to build your existing EJ257 block or a pair of our blank case halves. Save money and time by buying all the parts together from one place!

Kit includes:

  • OEM Heat-Treated EJ257 Crankshaft
  • ACL STD Race Bearings
  • Eagle Rods or Manley H-Beam Rodas
  • Your choice of either CP, JE, Mahle, Manley, or Wiseco pistons, with Rings

Please note the new lay-out below. The basic Rotating assembly will be as listed above. If you want to up-grade any items, just add them to your cart after you have selected the base rotating assembly.
