No, I haven't done any trails so I can't comment on that. When I had 35" KM3's (on stocl suspension) they would rub on the front mudflaps at full lock going up a hill or over curbs. I removed the mudflaps and the 37's with lift haven't rubbed on anything so far.
Is there any chance you could have bumped a wire going to the transmission? One of the older GM trucks I had the previous owner had a line going to the trans rub and scrape off the insulation and ground out causing really firm shifts. The oil change doesn't really make sense in terms of...
You may want to look into aftermarket wheels which will give you the better offset (+12 to -6 works well) and reduce the weight compared to the stock Sas wheels by 7-9 lbs and that helps offset the tire weight increase. I have 17x9 with -6 offset and BFG KO2 37's C rated which run a little...
I would never consider putting a thin wheel spacer like 5mm between the hub and wheel, it's like a washer that can work it's way loose. I believe you are overthinking it especially when you're hoping for 200K+ miles on a vehicle. At that mileage you will have already replaced most of the...
I went with the wheels that were priced decently, were in stock at the time and they had a 10% off coupon. I needed them right away as I had someone buying my stock Sas wheels/tires and the polished wheels met all the criteria. Heck, I didn't get the Bronco in the color I wanted back in early...
Are you talking about wheel spacers to push the wheel/tire out or a spacer lift to gain 2" of height? I don't think you don't want 2" wheel spacers to push the wheel/tire out that far. I'm not sure if the Big Bend wheels are wide enough for 315's, the stock Sas wheels are 8.5" wide and I think...
You may want to look at some adjustble coilovers so you can dial in the height the way you want it. I went with the ProComp adj coilovers when there were some good sales going on. I did not end up needing UCA's to get aligned but I'm sure it would have helped. The stock Sas wheels will most...
Yes, you can leave the shutters on with the Mishimoto intercooler. I chose to remove them and tuck the motor up into the frame rail out of the way so I don't get any codes.
