This is a complete set of YCP Brand Suzuki Vitara Pistons. These are sold to install into any D-Series block for turbo/forced induction applications. Each piston set includes: - 4 YCP Pistons,Pins, and Clips - Complete Ring Set Available in 75mm, 75.5mm, and 76mm Engine Bore Sizes. We have pushed the limits of these pistons on our own engines. We currently hold the world record for horsepower on these pistons in a stock sleeved D16Z6. We have used these in countless street engines that produced over 400HP on a streetable pump gas setup. - YCP pistons are made from a much stronger casting than OEM pistons (AC8A Grade) - 19mm floating wristpins fit aftermarket D16 forged connecting rods. - T-6 Heat treated for greater strength. - Highly resistant to heat. - Dual oil holes provide superior wristpin lubrication - Teflon coating provides increased piston life, improves cylinder sealing for less blow by and frees up more power from reduced friction. *NOTE: We recommend installing pistons with the arrows pointing towards the flywheel side of the engine for correct valve relief orientation and piston pin offset.
