Duratec stroker kits: more cubic inches, explained

By Esslinger Engineering - 22/10/2026 - 0 comments
More stroke means more displacement. Here are the Duratec stroker options we sell and what goes into each.
A stroker kit replaces the crankshaft with one that has a longer stroke, then matches pistons to suit. Longer stroke, more displacement. These are the options in our catalog.
2.0L to 2.3L
The 2L to 2.3L Duratec stroker kit is the common route to extra displacement. We also build finished versions: the 2264cc 2.0L stroker shortblock and the 12:1 2264cc stroker shortblock. If you are building it yourself, there are 2.0L Duratec stroker pistons in 87.5mm, 87.578mm and 88mm bore sizes.
2.5L to 2.7L
The 2.5L - 2.7L Duratec stroker kit goes further. The billet 2.5/2.6L stroker crank is available on its own for EcoBoost, DISI and turbocharged Duratec builds.
The 2.4L option
Our 12:1 2.4L long rod Duratec shortblock comes ready to bolt together. Or build with the 2.4L Duratec long rod and piston kit, in 9.5:1 to 14.5:1 compression.
