Hi everyone! I wondering what the purpose of the "frame horn extension" is, and if there are any issues with removing it to run a larger tire (I have a 2005, so should just be able to remove the bolts, if I'm correct about this). Thanks for any input you may have to this issue.

 

The frame horn is weird....I have 32" tires on my 2005 and the horns are no issue for me. Others have had to remove them or even cut off the welded ones.

 

I'm looking to run 265/70r18 BFG ATs (32.6") with the 2.5/3" Johnson Rod lift, and wondering if they'll fit without rubbing.

 

idk...it'll be close. The FWD end of the rear wheel arch may be an issue if you haven't already flattened that body-join flange. My Coopers are 275/65R18....that's typically 32.1" OD but back then Cooper's website cited them at 32.6" so idk....

 

Rods do NOT prevent rubbing. In fact, toss those 99 cent things in the trash and do a proper lift which included recalibration AND strut tower spacers. Because at that size you will rub and if you drop to factory bump stops, you will not move at all. If you have rear HVAC, you will have to move/relocate the cooling lines in the right rear wheel well. And best to move the front left sensor hardness out of the way since a tire could rip it.

I run 275/65/18 Bridgestone Dueler Revo II, which is pretty much the limit for "not rubbing" and even I have some very slight rubbing of the well liners. Horns are no issue. Rear cooling lines also not an issue. I did move the harness up front, but it was no needed.

 

So, the "best" way to lift it is with the off-road SYA kit and reprogramming via IID tool? I'm waiting for my Gap IID BT to be delivered next week. Just picked up the truck last weekend and trying to figure this all out to get it trail worthy!

Thanks everyone for all the advice!

 

Yeah... if we are talking SYA kits that is by far the best way to get mechanical lift, prevent larger tires from binding in the wells all when combined with GAP or rods for actual height adjustment. This is because the kit, I think, prevents things from going too far down and therefor rods may be okay to use since the sensors will not be pushed out of range.

And for the record, its already trail worthy. In fact what you are doing may add some clearance but it will increase center of gravity and increase wear on half shafts. I am sitting at 1.5" above factory height with just a sensor recalibration via GAP since this is as far as I want to push the hardware. No issue with going to off-road, access height or even going into extended, super extended heights.

 

So, I ended up just going with 265/65 r18 BFG KO2s... They fit no problem, no rubbing whatsoever... If I ever decide I need more clearance, I'll go with the spacers, but, for now, this seems to be working very well!
