Indy Dan SOS.... in 2017 you said you use the 2015 pistons in most motors... I have a 2017 axys, which pistons do you recommend?? 2018+? or 2015?

I have a machine shop making the highest quality Ti 17 titanium with dlc. Been proven in race cars for years with valves, wrist pins, etc..
Stronger then the steel that's used stock and lighter. Plus the dlc coating is wear resistant. So it's all good. Been using titanium since 2002 in two stroke motors with great advantages.
Pm me for pricing please .

Ratchit, I don't have permission to PM you. But I would like to inquire on a set of TI wrist pins. How can I contact you?

Dan, rebuilt m 2018 SKS 155 last fall. I had one cylinder down 6 PSI from the other. I did not hone or touch the cylinders. I installed SPI direct replacement pistons. I figured for the price I get them at I could rebuild it 3 times for the price of the OEM. I hope I didn't make a mistake. Oh and both cylinders check out the same after rebuild. Ran great last season.
