Leveling kit and bigger tire advice

I have a 2008 F150 Super crew 60th anniversary. I'd like to level the front end and possibly install suspension blocks in the rear to keep it level when there is weight in the box. Then I'd like to put bigger tires on my stock 18" rims.

Here are my questions:

1. How many inches leveling kit will make it straight with the rear?
2. What brand of leveling kit is recommended?
3. What's the biggest tire size I can go?
4. I'm thinking Nitto Trail Grappler, any other suggestions?)
5. What should I do to offset the bigger tires for programming (so the transmission and speedo function properly?)

Any other advice?

Thanks

It all depends on how thick your wallet is. I'll give you what I run and why. 04 F150 FX4 Screw. Rancho Quick Lift Loaded on front. This is new strut assembly with new spring and all. Unbolt the old and install new assembly. Will give 2-2 1/2 inches. Each truck is different. I chose this setup because of the adjustable gas shocks. 9 different settings and you can program the ride. I also run Rancho 9000 series shocks on the rear for the same reason. On a couple of other trucks I just installed the spacers and found a harsher ride. I run BFG AT T/A's LT285/65R 18 on stock rims. About 33". You should be able to run 35's with no problem. The FX4 sits higher in the back anyway and I run Firestone airbags in the rear but that is more for my trailer. Once upon a time you could get the dealer to reprogram for tire size. Don't know if they still do or not. Other than that you will need to buy a programer. Just what I run and why. I'm sure their will be more opinions on here.

Such is life. Just passing through.

1. 2" for a level truck. 2.5" if your going to lift the rear as well. Don't go with a leveling kit bigger than 2.5" as it causes extra stress on front end components.
2. autospring or hellbent steel
3. 35's on stock wheels. I would personally go 33's
4. Do you need a mud tire? All terrains will have better road manners and last longer
5. A programmer with custom tunes such as a gryphon or an xcal3

VMP and 5-Star tuned no more

I have a 2 1/2" rough country lift on my 2010 F150 supercrew 4x4, and I am running 315/70/17 Duratrac's but not on stock rims. I am also running a SCT programer, check my thread and you will see how my truck looks.

Thanks for all the advice.

I'm not keen on buying a programer since i only really need it for the tire size calibration so i called the dealer to see if they could do it for me and they said they could for $50. They also said they would have to plug it in to see what options are available for tire size, and their programmer would only accept up to a maximum size but they won`t know until plugged in. The service guy doesn`t do it often enough to know off by heart. Can anybody comment on this? What's the maximum tire size allowable in the dealer programmer? He also mentioned if you use a programmer yourself, the warranty is void?

To find out what size of a leveling kit you need park your truck on a level surface and measure from the top of the fender to the ground on the front and back and see what the difference is. As others have said don't go over 2.5" for the sake of wear and tear on your suspension. As for the dealers tire size options, I have no idea.

If you really don't want a programmer, superchips offers a device that reprograms for tire size only. Unless a programmer causes something to fail, they cannot void your warranty

thanks for the super chips idea...

For my 2008 F150 Suprcrew with a 6.5 foot box, I want to put on some 295 70 R18 Nitto Trail Grapples and want my truck to sit level. Do I need a 2 or 2.5 inch leveling kit?

Thanks

My understanding is 2" will level and 2.5 will level if you have something heavy on the frontend, such as a aftermarket bumper..winch..etc.
