This one-piece ring compressor will work with 81mm (3.188") cylinder bores including the Formula Ford 1600 Kent engine (standard size bores). No adjustment or setup is needed, just place on top of the block and drop the piston in. The gently radiused taper makes installation easy and minimizes the chance of damage to the rings.
Machined from 6061-T6 billet and Type 3 black anodized for long life. The bore size is also engraved in bright numbers 3/4" high -- a big help if you build more than one type of engine!
