I'm looking to buy 4.125 high comp. flat top pistons for a 170. I'd like to find a kit with all the gaskets and bearings. Where is the best place to buy them at. Not having much luck with finding any, thanks. Zeb

Zeb - look at the top right page and click [Parts, etc.]. Look for Jim Danforth/OK Tractor - I know he sells the 4 1/8 hi-comp kits. Be sure though that the exact compression ratio is documented by the manufacturer before you buy. Standard 4 1/8 kits are usually only 6.5:1 (WD45 style). I look at Jim's kits a couple years ago but then we couldn't get a straight answer from the maker on the CR (suspect it was 8:1) so I went with a 4" AGCO 175 kit (8.25:1) for my D17. Mike
