Can you buy wrist / gudgeon pins seperately from pistons?

[TERRA Operative]

I'm rebuilding my 4AGE Silvertop, and want to replace the wrist pins. I'm replacing the small end bearings, and the current wrist pins are a little bit matted off here and there at the contact point.
The pistons are fine to reuse, so I don't want to have to fork out for a whole set of pistons and pins.

Where can I get just the pins? Toyota only sell them with pistons....
Or, does anyone have a set of blacktop or aftermarket (lightweight) pins they could sell?

what dia and length do you need? i have a set from arias 3s pistons i think around

I need 20mm dia x 61mm long.
If they match up with what you've got, PM me!

i got some stronger and lighter ones fitted. i had a machine shop do it for me, they supplied them also, so i dont know what, where and who.
call up a few machine shops, they'll have something.

Sorry, mine are 22x60.

I did the wrist pin up grade on my 4AGE. The 18mm diameter pins mass is about 88-89 grams, I found some that were 64 grams. Many places offer pins, but 22mm x 61 is not specific enough. you will need to know down to the hundredth of a mm to get a nice fit.

I'm in the USA and I had to buy 8 pins since they had to be custom made. I delt with 4 companies... Wiseco, Ross Pistons, Precision(Precision Products Performance Center...building the future of performance racing!), and Trend (Trend Performance) Wiseco and Ross both turned out to be a waste of time, while my conversations with the other two helped CONSIDERABLY.

I spoke on the phone to Deb @ Precision(Precision Products Performance Center...building the future of performance racing! ), and Leif @ Trend (Trend Performance)

Precision has C-350 pin(steel), it was the pin I spoke about above that was 55 grams and $110 each. Precision ALSO has Titanium pins! They would have been only 44 grams, or HALF the mass of the originals!!! The titanium pins were also "only" $110 each.

Trend has the C13 pins(steel), their mass is 64 grams, and their pins are "only" $30 each... BUT I'm required to buy 8.

After nearly an hour discussion with Deb @ Precision... with her recommendation... I went with the Trend pins... and here is why... the C350 and titanium pins REQUIRE a DLH coating. This coating can wear off(say in 30k to 100k miles). This would likely cause a minor piston to pin noise, or might cause piston galling once the coating is gone. Since my purpose in this engine is to build a stout street engine, but to keep MAXIMUM reliability, the coated parts are not as reliable as the none coated one.

Awesome info!

Buying 8 isn't ideal, but it's not a deal breaker, I'll have a 4AGZE to rebuild soon too.

I'll shoot off a few emails.



Just measured my pins:
0.784" dia x 2.4" length
19.90mm dia x 60.90mm length

u need to measure the diameter with a micrometer to be sure.

That's what I did.
