PISTON RINGS



Lindsey Racing carries Genuine Porsche, Aftermarket (Goetze) and their own Lindsey Racing custom ring packs for the 100-104mm 4 cylinder engines. If you do not see what you're looking for here, contact us.

Genuine Porsche 100.5mm rings are no longer available!

Lindsey Racing uses a custom ring pack on their 100.5mm J&E and Mahle pistons but they are not sold on this web page. They do not fit pistons with stock ring groove thickness. If you have these pistons, you can contact us and get a replacement set.

* NEW * Our Lindsey Racing 100mm rings (shown below) are a custom ring pack we designed for 100mm Alusil bores that fit from stock 100mm bores up to .008" oversize if you're running a slightly larger custom piston or a skirt coated piston. They "REQUIRE" file fitting the end gaps and will allow you to achieve .015" end gaps on the top and 2nd ring and .025" on the oil ring on bores up to 100mm + .008". The chrome faced stainless steel top ring makes this a step above the genuine Porsche rings and you can get the gaps you want at a fraction of the price.



This allows you to take your stock pistons, skirt coat them up to .002" thick, hone the block accordingly, and have a ring pack that will still gap properly.
