What gives a stroker longer travel?



The crank is modified, the big end bearings (where the rods connect/mount onto the crank) are offset welded and ground to basically push the distance from the center of the crank to the center of the con rod big end bearing out farther. It gives the piston more up/down distance to travel, increases the speed the piston travels, and also increases the leverage the piston's force (combustion) while at the same time increasing displacement (engine size).

In short, a stroker is an engine with a crank modified to increase the size and power of the engine.

Expensive, but very effective.
