...the only real reason to do it is to fit bigger tires.
Are you guys (Allodial and Trynian) referring to using the rod-mod in general?...or are you referring to going beyond a 2" lift to a 2.5" lift?
I'm a part-timer on the lift (install before "gameday") and I don't see a down-side to using it as needed. ...but what the hell do I know? I think "time will tell" is the key phrase here indeed.
Referring mostly to using it full time. Some, especially on the UK boards seem to think it will cause problems.
I don't know either way. It probably has no issues using it the way you do. I just personally see no reason for me to use it when I can get that extra lift anytime I need it via super extended.
Some like it so they can go over 30 in offroad height, I have no need to do that either, if I need that level of clearance I would not be traveling at 30+.
Some like it for using oversized tires, if you get a fault and go to the stops you are in a much worse situation then if you stick with 31.5" or less tires.
I have done most all of the most advanced trails in SoCal with no issue with 31.5" BFG's. Some that even have claims of being impossible without larger tires.
Plus, I don't want to be switching it out at the trail as I do not care to drive to the trails in offroad height.
It is just my personal preferance.
