: H2’s and Rancho 4" lift

Would putting 3/4" or 1" spacers on the front be a bad thing?


Here's my delimia. Have Rancho 4" lift. Have a set of BF KO 315-70R17 tires that have 5K miles on them which I took off months ago when I abandoned my Weld Evo Renegades due to chrome plating defects on 2 sets and went with 16x8 wheels. Now I want to go back to the 315's but need 17" wheels. I would like to run the H2 chrome wheels which I beleive are 5.5" backspacing. In order to do this with the lift I would need to get the H2 wheels out about 3/4"...which brings me to my question.


Thoughts?

Buy a spacer............


They make them for the rear axle to line up the wheels front to back.


Someone here posted it.........


Do a search.

I did do a search and read all the info on spacers on the "rear" but didn't find anything about spacers on the front...not sure if there would be any difference. I've also sent email to wheeladapters.com asking his opinion and pricing. IIRC I think I also read something where spacers may be required on the rear to fit H2's with lifted truck...I need to get this all straight before pulling the trigger on some H2's I have a bead on.

Talked to wheeladapter.com. Sounds like my plan won't work. 3/4" spacer would work fine but then I'd have issues with the wheels studs being too short and he said he didn't know anyone who makes longer studs for our trucks ...they'd have to be pressed out/in, etc. Sounds like it would be a big hassle. Darn.

i originally planned to do the same. adviced not to put any on the front. front gets a lot more impact driving. plus, short spacers require cutting oem studs.


H2 wheels not recommended for off roading since they are made of soft alloy. low load limit. if you have a lift with replacement knuckles (Fabtech, Ranchoo, etc.) backspacing is too great. . . .

Deadeye,


What is this statement based on?


"H2 wheels not recommended for off roading since they are made of soft alloy. low load limit."


I have not heard of anyone damaging a H2 wheel or breaking one while off road, have you?

No I have not. But think about the load rating of your stock wheels and the weight of your truck. The H2 wheels are made for a vehicle that is for show not for tow, haulin, or off roadin. The load limit, IIRC is less that 2K which is like load range B or C. Our trucks are intended for Load Range E.


Off roadin can trash wheels easily if slide off a road, into a rock, etc. I think the H2 wheels are ok for every day drivin but I, personnaly, would not risk my life or my costly vehicle using an under rated wheel (or tire).


One of the reasons I went with my EVOs is because of this.

I think the H2's capabilites are often overlooked because of the type of people that buy them and how they use them. The truck is fairly capable off road, how many trucks or SUVs come stock with 35" tires? Not sure what you meant by IIRC load range B or C, but the H2 comes on load range D tires, load range E tires are very limited in that size and on/off road tread. The wheel centers have to be pretty strong to handle the leverage a 35" tire can put on it, and that is what they are designed to have, I would be more concerned putting a large tire on a wheel that was not specifically designed to run such a large tire.

H2 is more capable off road than an H1. Seen it proven many times on ride trips during development.


Also, the load rating for the H2 tire alone is more than that of the standard OEM tire on the 2500HDs.


HTH.

BS - wrong on both accounts. H2 has the same suspension as our trucks. H1 has a very good independent suspension front and rear and is used by the MIL. Check some other threads on this subject.


H2 wheels are made from cast alloy they are soft.

IIRC the H2's are rated a little bit less than our oem's. But, a hummer is rated at 8600 gvwr. Not much lower. I have yet to see anyone bend or break H2 wheels.

I'll bet you my next military paycheck that I can go through stuff with a Mil POS hummer that a H2 wouldn't be able to follow through.


If I can find out if they're compatible, I'm going to buy a set of H1 rims. I plan on getting the rims beadblasted and then clearcoated so they look somewhat nice, and I'll be running on 37's with runflats then. Big deal about not being able to balance them.. lolEdited by: SpoolinTurbo
