I'm not exactly sure how you would measure your approach angle Swanny.Blue,
I am wondering if you had ever documented your Approach Angle Before the Bumper change, as it looks LARGE !!! And that means Alot.
ANY 4WD. VEHICLE THAT HAS GROUND LIFT, AS IN DISTANCE FROM THE GROUND TO THE LOWEST OF POINT VEHICLE SUSPENSION IS KNOWN AS CLEARANCE, THAT AND TWIST MAKE THE FORMULA TO TRACTION, A NON SPINNING FORM OF MOVEMENT.
What I did measure (before and after) was the distance between the bottom of my fender flare and the top of my front tire and there was essentially 6 inches (give or take an 1/8 inch) between the bottom/center of my fender flare and the top of my front tire.
It was still 6 inches after the bumper was installed, so, there was virtually no change. Maybe it dropped 1/16th to 1/8th of an inch but nothing that was noticeable to the naked eye and nothing that will have any adverse effect on my clearance as far as I can tell.
It doesn't feel like it handles any differently either.
Keep in mind, most of my front suspension components have been upgraded. I have Bilstein HD B6 4600 front shock absorbers, JBA UCA's/balljoints and the 2 inch RC lift. The only thing upfront suspension wise, that is still stock are the springs.
I think that's why I had no noticeable drop when the bumper was installed.
I have heard other people have seen a measurable drop - some have reported up to 1 inch.
