Piston skirt expanders

[Brian T]

I see while searching here and see that some of you have come across piston skirt expanders, I have those old antique split skirt pistons that haven't been sold since who knows when, my #2 has a louder than I like slap, I have no blow by, and no problem with the cylinder walls.
I am biding time for other engine work, -- If .90 over pistons were available I would replace them, I have never seen these expanders for sale, if someone has 4 they do not want please let me know.
Thanks in advance.

Try Egge they make pistons in most any size or shape.

What kind are you looking for--one type needs the wristpin removed (take pistons out)

and there is another type like a big snapring that only needs the pan off

Thanks Kurt,
I am familiar with type that fit between the wrist pin bosses, its the big snap ring ones I believe would work, thanks for reply.

have you thought about having your current pistons knurled?

I got a set of the piston expanders that fit below the wrist pin on eBay a few years ago. This type expander could be installed without removing the piston.I installed a set in my september 29 and it expanded the pistons so well that I had to hone the bottoms of the cylinders for more clearance. This isn't a perfect fix but has worked and quietened piston slap for the past eight years. This is just a fun car that isn't used for primary transportation. The best bet would be new oversize pistons, It all depends... If you chose to use expanders, use them on all four pistons or balance will be way off .
