Hey Guys! I haven't posted to this thread in a long time due to school and work but have a week off for vacation and decided to install a lift for my commander since new tires are long overdue. But before I do this I just had a question. I am planning to get a 2 inch RRO lift, 1.5" Spidertrax spacers and 265-70-17 Wrangler Duratracts or Open Country II's (haven't decided on that part yet.) So my question is will this lift and these type of tires interfere with my speedometer or even my transmission? Could it potentially harm anything do do with the commander (engine,trans,suppression)? And if so are there steps I could take to prevent problems if I go thru with the lift and bigger tires?
