* Specific trim level: Different Suburban trims might have slightly different ground clearances due to suspension or tire size options.
* Modifications: Aftermarket modifications like lift kits significantly alter the angle of approach.
To find the angle of approach, you would need to consult the 2002 Chevrolet Suburban's owner's manual or a reliable automotive specifications website which might list these figures for different trims. Even then, these are often manufacturer-stated ideal conditions and real-world angles might vary slightly.
