Pistons ? quick question

[amceaglesx4]

Are all jeep 4.0 pistons the same ? On my build its a 99 block bored 60 over using the 258 crank and stock rods. Does it matter what 4.0 piston I use that's 60 over ? Thanks

Some of the advantages of ordering a custom piston is that you're no longer required to deck your block to maintain a quench area.
The ICON KB Piston requires a block to be decked about .045, and is priced about the same as a custom.
So if you figure the cost of decking a block, my custom piston is actually a smokin deal.
