I'll have the body lift on this weekend (with the break in the rain, maybe even tonight?). I have no rubbing in normal driving at the moment aside from a small amount of rub in reverse at 3/4 lock to the right, none anywhere else. I am looking at steering rack upgrades like the Mayhem kit or the Outfitter Design kit to remove the slop in the steering so I don't brake a rack. The tires are just as wide as a 35, but a little heavier so it will eventually need to be done. If your crossmember bushing is worn, now would be a good time to replace that too so the front doesn't move around and stress the differential housing and gears.

I have a custom made cross member with heavy duty bushing. I also custom installed a Chevy 2500 HD steering rack in my H3 so pushing 37" tires around shouldn't be an issue. I will cut off the rear triangles this weekend to make room in the rear. I should have this project done by end of next month. ** I also used the Ultimatepowersteering bushing kit to hold everything in place. I would suggest using their bushings. I have absolutely no movement in the front end and nothing has broken even at full tilt power rock crawling.

What is the weight on those? I found the power hit on my 37" MT/R's with the I5 and 5 speed to feel like the I5/auto on 35's due to the lower final drive and peppier around town because of the better/more ratios. Here's mine before the BL and waiting on the slider's paint to dry.
Can you reach full flex? I wanna know if this is viable

More hard like Delrin but the texture itself feels almost oily like a rubber... sorry that doesn't sound clear but maybe I can say it like this: Hard as in holds it's shape and would brake if you tried to super twist it but soft like a knife would cut right into it easily... I do think its great though and it is holding my rack solid in place which is the best I can ask for.

From what I understand and have researched so far as a person going down this road currently you have to have the 1" daystar body lift if you want full flex. If you are ok with 70% flex and don't hard core off road then nope you don't have to have a body lift. You do have some limited turning and rubbing without the 1" body lift. With the lift you are pretty clear at all corners from what I know so far?
It is like GreatDaneHummer said above. However, the problem is that each tire is a slightly different size (in diameter and for side biter size), and it really depends on what rim you are using. There are also some slight variations from vehicle to vehicle for tolerances that might be able to be adjusted for when the body is lifted up and moved around for the lift. Using the stock 16" rim is really the best option for keeping the tires tucked in and light weight but tire sizes are somewhat limited. I think there are about 5 tires TOTAL that fit a 16" rim. The stock rim is also really light at 23 lbs (I saw one reference to a 20 lb shipping weight before packaging, but I don't think it was right). As far as the flex question goes, I watched a friend in an H3 with 35's and no shackles come down hard off an obstacle and rip the rear inner fender liner out. On mine, I've seen 35's kiss the inside of the fender well regularly. You need, at a minimum, 1" more lift to get the 37's (one inch larger in radius than the 35) to clear when fully flexed out and if wheeling very hard it may not be enough just like with those 35's.
Thanks, that is a good description. It's strange, but it does make sense. I think I will put one on my wife's H3 that needs the bushings replaced and one of the others on mine and do a long term comparison between them.

The problem that we will all have is we are going under the notion that all 35" tires and 37" tires are "actually" their perspective size. Cooper tires run smaller for example: Discover STT Pro in a 315x75x16 is 34.53" in height. Under weight on the H3 it actually measures 33.81 at 35psi. This is the same way the Mickey Thompson Baja Claw TTC's are but take a look at Pitbull Rocker Radials and they are rated at 35.13" and measured at 35psi they are 34.73 larger than the Cooper tire not mounted....
My point is some 37" tires will fit while many of the larger size ones like Pitbull have no chance of fitting without major work.

A very viable option to maximize performance is running a larger 35" like the Pitbull Rockers but do the 1" body lift with it to get maximum flex and off road performance. Still do the trimming to get lots of clearance... Just an idea.

What do they measure with weight on them now??What is the weight on those? I found the power hit on my 37" MT/R's with the I5 and 5 speed to feel like the I5/auto on 35's due to the lower final drive and peppier around town because of the better/more ratios.

I dunno. I seriously don't worry about it or I might never air down off road.

After doing the 1" body lift maybe even with the 37" tires I can lower down the torsion keys a little to get the ride back to being decent without ridding like a Jeep lol.

I got in my first wheel to check fitment but I can't upload photos still... I will have the rest of the tires showing up over the next 3 weeks.
