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 machined to the standard 90.5/92mm size, so they'll slip right in.  This is an excellent choice for cases with 10mm studs, as the case will retain maximum case strength from not being opened so much it exposes the case savers.

Head size: 94mm

Case size: 90.5mm
