I believe that the Cranks have 5" backspacing and 0 offset. Will I be okay with the lift with these wheels and tires or will I need spacers? I am totally new at this lift kit thing and appreciate the great advice that is available from forum members - Thanks!
You should have no issues rubbing lock to lock or rubbing your swaybar. You are basically running close to a 33x11.5 tire with your 5" BS rims. If you add a 1.5 spacer to your already 5" BS rim will put your tires well beyond your stock flares and you may have issues with the POPO about wheel coverage as well it will put more strain on your balljoints having 3.5 BS
With the lift just be mindful of where your axles shifted as the rim may sit a little closer to the suspension components on the one side where they may rub on your Rear swaybar links or front swaybar. However, hopefully your kit came with Adj Track bars to get your axle centered again.
If you do have some minor rubbing on your front swaybar a simple fix for that is to adjust your steering stops which can take away some of your turning radius, but it's a simple adjustment
and tools you require
9/16 Socket and Wrench
(2) 3/8 washers (at minimum)
The steer stop bolt is located on your front left and right steering knuckles. Using a 9/16" socket, remove your Jeep JK Wrangler’s steer stop bolts. Start with (1) 3/8" washer in each side. Retighten bolt. Then test.
Add more if needed if you are still rubbing.
