spi pistons

[custom polaris 600]

I am wondering if any one has run these pistons, and if so how did they run compaired to weisco and oem pistons. Blew the piston skirt on my 800 and need new ones. Found a complete kit for 185 plus shipping for 2 pistons and rings and the complete top end gasket kit. Needing some advice on these pistons. Thanks

I run them in all my sleds. They have worked flawlessly for me. Many on here run them. I used to run only oem but have found these to work well for me. I've had Wiseco's and oem fail me, but havent had SPI's let me down yet. Just be sure to check the ring end gaps and adjust accordingly. Some will say not to use them, but if you change them out every 3 or 4 seasons depending on the miles, I think you'll be happy with them! Sprocket.

I have run them many times with zero piston fail issues.

Ditto what everyone else has said, I have never had one fail.
