Head Hoggers Tapered Ring Compressor M8 4.250 bore

Our patented tapered ring compressors absolutely PERFECT the piston installation process. The days of that ridiculous spring loaded plier contraption are over! Just line up your rings, pop the compressor onto the base of the cylinder and drop it onto the piston! It really is that easy, and you'll never catch a ring again!

(Each compressor will do up to .010" over the labeled bore size.)
