jimoshel Posted April 17, 2015 Posted April 17, 2015 Isn't the piston and rod the same for all 4.0's ? Or was the '88-91 different?
sinkrun Posted April 17, 2015 Author Posted April 17, 2015 I think from what I have seen and read there different on the early ones.
jimoshel Posted April 18, 2015 Posted April 18, 2015 I've got a '88 and a '94 sitting side by side. I could just go drop the pans, pull the heads and compare them, but that's a lot of bother just for a little knowledge.
sinkrun Posted April 18, 2015 Author Posted April 18, 2015 When I look at new online they list 96 and up the same not sure about the lower years I will have to do some looking. Also I may have a line on one from A local jeeper so don't take anything apart yet.
jimoshel Posted April 18, 2015 Posted April 18, 2015 Belay that. I have a 1995 piston and rod. It appears they are different from the 96. I can't find any info on them. Maybe you can. Jim
HOrnbrod Posted April 21, 2015 Posted April 21, 2015 Correct, the 95 and 96 pistons carry different part numbers. These are the standard piston assemblies available for the 96 engine: 19964798329, 6, "B" Size, 3.87424798330, 6, "C" Size, 3.87464798331, 6, "D" Size, 3,87504798332, 6, "E" Size, 3.87544798333, 6, "F" Size, 3.8758 The rods are all the same.
