A 4.6L stroker in a TJ makes for a big performance boost, both on the street and the trail. The owner of this Jeep was relatively happy with his 4.0L's stock performance until he added big tires. Even properly geared, street performance deteriorated, and being a red-blooded, power-mad American male, he wanted more. Other than a supercharger, the stroker offers the biggest single boost in torque and power you can buy ... and all the other smaller enhancements out there just build those numbers higher.
