040 Bore: 3.538''/. 040 Stroke: 4.250'' Displacement: 1369cc Valve Reliefs/Dome: Valve pocket depths are measured from deck height.Dome Volume: -1.5cc Int. 178'' / Dia: 2.000'' Ext.
178'' / Dia: 2.000'' Compression: 9.5:1 Compression Ratio / Flat Top Features: ArmorGlide skirt coated. If these pistons are used without the Screamin Eagle heads then compression ratio becomes 8.5:1. Assuming no other parts have been changed or altered that might affect compression ratio as well. Kit Includes: 2 forged pistons, 2 ring sets, 2 wrist pins and 2 pairs of wrist pin clips.
Dedicated forgings used for superior strength to weight ratio utilizing aerospace alloy. Horizontal slot-pin oiling reduces friction and provides scuff resistance, along with a pressure seal groove for maximum ring seal. The skirt shape (barrel/cam) is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. An optimally designed skirt shape provides stability which is important for proper ring seal and reduced friction.
