Achieving more output and reducing fuel consumption are the two of the most important goals in the world of engines. The achievement of this goal has seen several different design concepts being pursued. The working mechanism behind engines has been revolutionized through the invention of stroker engines. The working mechanism behind stroker kits is increasing the distance the piston has to travel when the engine is operational.

In other terms, increasing the stroke in an engine refers to increasing the distance the piston travels. The reason for increasing the distance covered by the engine is making the crankshaft rotate faster. The increase in the rotation of the crankshaft leads to the generation of more torque, leading to improved acceleration in the vehicle. All these lead to faster rotation of the wheels.

When torque is very high in a car, it translates into lesser time needed for it to reach its top speed. However, this does not mean that the power/top speed will be improved because that is never the case. This implies that even though a car with greater torque is able to accelerate faster, its top speed remains unaltered.

The distance from the top dead center to the bottom dead center of the cylinder that is covered by the piston is what is referred to as the stroke. Increasing the distance to be covered by the piston is known as stroking. There are three main ways to increase the stroke of the engine. Increasing the height of the block deck or increasing the cavity of the cylinder is one way to achieve this. This can be done by acquiring a customized block deck designed for stroked engine.

The second method of stroking an engine is to extend the length of the rod that is connected to the piston to make the piston rotate across a bigger diameter. However, this approach carries the risk of the rod colliding with the cylinder head. Avoiding this involves using aftermarket pistons that come with extended rods that are connected higher inside the piston itself

In the third way, one can buy a stroker kit from aftermarket stores. One can even have the kit assembled for them by the store in some cases. These kits are made of pistons, connecting rods, crankshaft, main bearings, rod bearings, and piston rings and pins. When installed, the kits increase torque substantially.

Stroked engines come with several advantages that make them worthwhile. The first advantage is related to the production of more torque and higher displacement. The second advantage is that they increase acceleration and attainment of top speed. Lastly, down shift is not needed when accelerating from lower velocities because the engine is stroked.

There are a few shortcomings that are associated with stroked engines that make them not suitable in all cases. The first disadvantage is that they cause accelerated failure and wearing out of the piston. In a stroked engine, the piston has to cover a longer distance within the same time as in an engine that is not stroked. This results in the piston being overworked, hence causing faster failure. Faster wearing also occurs in tires.
