Features: Machined from Wiseco sleeve forgings to offer the same toughness as Wiseco's forged pistons. Hard anodized and PTFE coated for low friction and prolonged wear resistance. Sleeves have a smooth radius that tapers down to the specific bore size. Compresses the piston rings smoothly and evenly. Greatly reduces the difficulty with installing thin high-performance oil rings. Available in a WIDE array of bore sizes.  Order the ring compressor for your exact bore size, after any over-boring, of course.   A few common sizes:   85mm - a stock Zetec 2.0 found in Focus, Contour, ZX2, etc is 84.8.  When overbored .007", this brings the bore to 85mm 85.5 - Zetec bore to .027" oversize 87.5mm - Duratec / MZR and Ecoboost 4 cyl engines, 2.0 and 2.3 L.  Stock bore 88mm - Duratec and Ecoboost 4 cyl engines, 2.0 and 2.3 L over bored .5mm or .03937" - might be stated ".040" over" nominal.  Typically, overboring this amount would require the block to be resleeved. 88.5 - Duratec and Ecoboost
