Stainless split pins on trailer?

I have noticed the original roller split pins beginning to look a bit dodgy (badly corroded). There are 132 of them and I only want to replace them once! Any thoughts about going stainless? Should I just stick with the original cheapos?

+1

The galved ones will be electroplated and not hot dipped and the galv. will be gone in 6 months.

Thanks guys. I was a little concerned that s-s might effect the trailer, but hey! I hadn't considered replacing the washers, but I know it makes sense. There are 128 roller pins, all set in the concavity on the sides of the roller - abu@@erto work at. I only want to do this once

Any stainless in contact with galv will accelerate the corrosion of the galv. This is particularly worse when you chuck seawater into the mix. We go to great expense & effort to ensure stainless & galv never meet. Even stainless will corrode in seawater over time. You can fit stainless pins, but where they pass through the ends of the galved roller carriers will corrode. You can get hot dipped split pins.

Not wishing to start a fight here, Pikey, but I've found the opposite to be the case. There must be something different in the application....
