WISECO - K2788 - Piston Kit - 3.875” - 103 Cubic Inch | 96 Cubic Inch Bored to 103 Cubic Inch - Twin Cam
A piston that fits loose burns oil and loses compression. One that fits tight seizes under heat. The WISECO K2788 is built for your 3.875” / 103 Cubic Inch | 96 Cubic Inch Bored to 103 Cubic Inch / Twin Cam engine with the kind of precise dimensional control that sits exactly where it should — delivering clean combustion sealing and smooth cylinder wall contact from the first fire-up. Wiseco's high-tech manufacturing ensures greater operating strength and lower expansion at high temperatures. Kits include forged pistons with ArmorGlide™ coated skirts, rings, retainer clips, and chrome piston pins. Engine Type: 4-Stroke. Every serious rebuild deserves components engineered to this standard, and the K2788 delivers it.
