Hello everyone, I'd like to know who to talk to get some top guided piston pin spacers. Who makes these? I'd like to get some quotes for my engine build. Thanks!

Assume you are talking about piston guided rods and the spacers for end play at piston. We just made our own on the lathe but you might try CP or Gibtech maybe they offer something?

Thats correct Al, thanks

I have never seen them for sale.

I have assumed they were made for each application.

The one engine I had with piston guided rods the guy I got the pistons and rods from made them.

I think this idea came from NASCAR, I don't know if they still use these or not. However you might check with some of the NASCAR engine shops.

Let us know what you find out.

Id certainly call whoever made the pistons, as they should have been "correct" for the application from the get go. They are such a custom thing I am not sure anyone does the couple times we needed some we just made them .They MUST be made from a dissimilar material, bronze is usually the go to
