I regeared to 4.56 and notice on the highway going up fairly steep hills (elevation ~5000 ft above sea level) I still lose speed even though RPM is 2800-2900. This happened on Hwy 80 from Evanston WY to Cheyenne, for those who know this road. Is this normal with 5.5" lift and 32x11.50 tires? That is, does it cause enough drag to slow my XJ down to 55 MPH? How about you Easterners who drove to Moab...how was it going through some of the passes for you? For me, it feels like the brakes are dragging, even though I know they're not. My buddy had no problem driving the same highway in his stock Dodge w/ 6 cyl engine. Actually, his tires are slightly larger than stock. I'm wondering if I have a tranny problem. I mean, it feels like I have stock gears again, tho' the RPM gauge shows otherwise.
Also, for those who regeared and run ~2600-2800 RPM on the highway, did you notice your engine heats up higher than before the regear? Mine stays between 2/3 and 3/4 on the gauge, which is too high for me. Everything in the cooling system was replaced, so I'm thinking a plugged radiator. Looking for input from similar setups on what you're getting on temp gauge. Hope this made sense.....I'm in a hurray. Thanks for any input you can provide.
