If you are craving more power from your vehicle, engine modifications are great place to find it. Rebuilding a motor with a few go fast parts is fine for modest improvements, but if you want some serious grunt there is no replacement for displacement. Complete Infiniti Qx4 stroker kits are one of the best ways to increase displacement and power. With complete Infiniti Qx4 stroker kits you will have stump pulling torque and tire squealing horsepower that will blow the competition out of the water. We have a good selection of Infiniti Qx4 stroker kits at Andy's, so you can pick the perfect one for your application and get ready for a drastic transformation.

The theory behind a stroker kit is quite simple. An engine's power is largely determined by the volume of air it moves in and out. The stroke of the crankshaft determines how far up and down the piston travels, and thus controls the volume of air moved. By increasing the stroke of the crankshaft you increase the overall displacement of the motor and the volume of air that it can move. This means more power. Stroking is not just a hot rodding technique; it has been used frequently by OEM manufacturers to utilize the same motor for applications that require a little more power. Tried and true, Infiniti Qx4 stroker kits are a great way to maximize engine performance.
