What is the primary benefit of installing this stroker kit?

The primary benefit is increasing the engine's displacement from its stock size to 2.1 liters. This fundamental change allows for greater potential in power and torque output, especially when combined with other performance modifications and tuning.

What components are typically included in this full kit?

A full stroker kit like this generally includes specially designed pistons, connecting rods, and often a crankshaft or other components necessary to achieve the increased displacement. The goal is to provide a matched set of parts engineered to work together.

What are the implications of this kit not being CARB approved?

This means the kit does not meet California Air Resources Board emissions standards. Consequently, it cannot be legally sold or installed on vehicles registered in California.
