Yeah I've got the same gears, (03 rubi) and curious how that would hold up. My daily commute is about 8 miles, so I really only drive around town and trails. Why did you decide on 4.88 instead of 5.13?
The antirock fits through the frame hole that is parallel to the front bumper. You may be able to get by depending on bu.per. but my warn curves too much to allow a solid strike with a hammer when placing the antirock's support system, they fit very tight into the frame.
Because I still want to run the jeep 75 down the highway without screaming, 4.88 puts the 5th gear cruising revs just over stock ratio; 5.13s would put on another 150-200 RPM.
All the bumpers I am looking at shouldn't prevent a BFH from installing the antirock, they hug the frame rail and have cut outs around the tube area. I figured that was it, just wanted to make sure there wasn't something else I had overlooked (you never know)! haha.
Just waiting on all of my Metalcloak gear to show! It was between them and Currie for the lift.
