Im wanting to put H2 wheels on with 35x12.50x16 tires on. I just bought a 01 2500HD 4x4.

Will this work with no problems:
-Cognito 2-3" front leveling system
-Cranked torsion bars
-Longer pro comp front shocks
-Cognito Pitman/Idler Upgrade

And do I need torsion bar keys in addition to get it higher than that?
Doing it this way is a 1/4 of the cost of a Cognito 4"-6" full lift.

And then a block setup in the rear to bring the rear up to right height. I believe I have read I need a 1" Rear block, where do you recommend getting it and how much is it?


Any suggestions/input is appreciated.

I'm assuming you meant 17" tires, because the H2's are 17's. And yes that setup should work. The actual 35" tires might be a little larger than the 315/70/17 but it should still work. Try cranking your t-bars first. Most don't need green keys. You might not need a block at all in the rear. Check my garage, my 03 has a 1" and my 07 has none.

The H2 wheels will not work with the Cognito arms, unless you get spacers. I think mine are 1/4 inch. The wheels hit the arms at full turn. Other than that they work fine.
But if I had to do it again I would have left the stock arms added green keys and Bilstien 5100 only. I can't get the alignment perfect with the Cognito arms unless I add a 1" block to the rear and crank the frt more.

edinning,
Not saying your wrong but how long ago did you buy your Cognito UCA's? The new ones don't need spacers. 100% spacers not needed. I just did a install here for a DP member w/ H2's on 315's. Yes you can make the tires fit.

AidanN20,
PM me if you want all the parts needed shipped to you to make this work. I have kits instock.

Most people that try to run 35's run into trimming issues, rubbing and premature wear on the front end. I would do a search on this and you will find some topics. There are a few people that have run 35's on here and have had to do extensive work to the fenders, bumper and valence to get them to fit properly without issues. Good luck.

 

[AidanN20]

Extensive work for trimming/rubbing??

Is that even with the leveling kit in the front and the torsion bars cranked up or just the torsion bars. I really dont want it to rub so its hard to get a clear answer. Some say it will work, other say no.

Also did you just use the Cognito leveling kit and crank the torsions or did you have to use keys?

Your truck is a 01, I would say you will need keys. Yes we cut the plastic to make them fit. How much trimming is something that you will need to be open to if you are going to start this project. Alot or a little of cutting is all different per who you ask and what they are ok with them selfs.

Will they fit with no problems? No
Will you need to trim? Yes
Can it be done? Yes

I run 33's on my truck and I just used keys, 35's are too big.

 

[jschmid]

What about gearing down? I see a lot of folks using the H2 wheels but those seem pretty tall for the stock 3.73 differential gears. I was looking at going to 4.11 with the 315s. On the highway 3.73 would be fine. I don't tow, but even in sand the engine and tranny seem to be working pretty hard with the 3.73. Seems like with the 315s it would be a killer.

Another question. What about wheel travel with the Cognito leveling kit and
H2/315s? Any issues with this when offroading? Do they hit the wheel well, reducing travel?

Invoice date 6-8-06. I told the guy that I was using H2 Wheels and tires. Part#LK100007
I used green keys,Bilstein 5100 shocks.

I called Cognito today. There has been a revised arm. They sold be the old stock. The new arm is rounded on the end and not square like the 1 shown on there web site. I have also had 2 alignments done and the alignments isn't to OEM. They said today to adjust the Caster to 4.5-6 and the Camber should go to 0. Time for 3rd alignment a $100 ea.

The money spent on the arms isn't worth it to level the truck.

edinning,

Where did you buy your Cognito parts from??

 

[edinning]

edinning,

Where did you buy your Cognito parts from??

Direct from Cognito.
My thoughts were I would get the best advise and service buying direct. I had the alignment shop talk to them the first time the alignment was completed. They said that the alignment would go back to OEM. Today they tell me that the Caster needs to be set out of spec and the camber will adjust.

Can I ask why it matters where the products were bought from? I don't understand that line of questioning.

I agree, when you need something go direct to the source/maker and you will get everything you need and in some cases you get the perks of free stuff, that is if they will sell direct to public instead of through a middleman for a terrible mark up. I buy from directs and skip the mark up. Always smart.

 

[edinning]

It cost me more buying direct. But the service on the back side is usually better if needed. This is very true of Banks. If you buy from Banks you pay more but the service and warranty is a little better,I have not seen this of Cognito. I don't think the service would be any different had I bought the kit from norcaltrucks. In fact the pictures and info are better on the norcaltrucks site. By looking at there pictures I am going to re-route the ABS line. If you buy from them you pay more but the service and warranty may be better.

 

[AidanN20]

Cognito is literally 4 miles from my house and across the street from them is Shocker Motorsports....

I think I will go by and talk to them in person and get the skinny on the alignment issues with the leveling kit arms.

 

[edinning]

I would let them do the install and alignment if they are that close.

Well it looks like I did a truck that worked and he went direct and his didn't work.... where are those perks again?

Nor-Cal Truck does not mark up Cognito pricing.... So you would not be wasting your money going threw us.

Now you tell me.
norcaltrucks.com has better photos and a better site than Cognito.
Had I known I would not have bought the old style arms as I don't like using a 1/4" spacer.

 

[jla]

if are so set on running H2 wheels and tires, you should have just bought an H2.
