These stroker 92mm pistons and cylinders are truly a great value:  Super nice, and at a great price. The super thick walls are more resistant to warping with heat, making them especially durable for extreme use, heavy loads, or high miles.  They require your cylinder heads to be machined to the size normally used for 94mm cylinders. The engine case is also machined to the standard size for 94mm cylinders.

Head size: 94mm
