kits are precision machined to Japanese OEM specifications. Using low-expansion, low-friction piston alloy resulting in an extended life span of the piston. Our Teflon coated skirts uses a rolled-on application process which provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction, and help’s to eliminate cold seizures. Machined smooth heads helps to reflect combustion heat and reduces carbon buildup, protecting the top of the piston resulting in increased horsepower and fuel economy by up to 6%. Kit includes piston, rings, and circlips. Outlaw offers direct replacements for the original equipment as well as hi-compression and a variety of oversize’s to meet your ride's needs. Please note some product images may be a stock photo and the item you receive may be a different configuration than what is pictured, but we guarantee item will fit listed vehicles.
