Twin I Beam Leveling kit

94 F-150 2WD with twin I Beam suspension
So I’ve been wanting to level the front on the truck for a while to put slightly larger tires on it. While researching this I’ve been getting conflicting information.

all the leveling kits that are essentially 2 inch blocks to put under the springs, say except 2wd twin I beam etc. why is that? I know that I will have to replace the camber bushings with adjustable, and that’s all fine good. Is there any other reason why I can’t do this??

as far as tires I’m not trying to go crazy by any means. 31x11.5 on 15’s . And yes I am aware that under load the rear will sag. However the rear is fitted with airbags so It can be raised up.

thank you!!

I am not sure about that, the 4wd and 2wd springs are the same.

You could do what I did to my son's '95 F150 when he wanted a leveling kit - I put F250 460 springs in it.

I have installed 1 1/2" blocks (spacers) on two 2wd F150's and one 2wd
​​​​​​F250. I have never had an install issue. Sandy
I am adding that the max camber for 2 wd is 2*. 4wd is 4* I think. I don't know if you adding larger tires will cause a camber setting that you can't achieve. I use stock tires.

Twin I Beam is the front suspension. Therefore, if the leveling kit includes blocks in the back, it’s a lift kit, not a leveling kit. To level the front end, f250 springs are fine. Anything over 2 inches, and drop brackets for your I-Beams, make it much easier to align, as they help to correct the geometry of your front suspension and steering. I wanted to level my 2wd, so I got the f250 Moog 822 springs. It did lift it about 1.5 inches. It wasn’t enough. I went with the Rough Country 2.5 suspension lift, and I’m happy with it. Here are pics from stock, then f250 springs, then 2.5 RC with 33x10.50 BFGs.

Stock on 255/70r15

Moog 822 f250 springs, still with 255/70r15s

You can do F250 springs like was mentioned. I have used Superlift leveling coils on 3 different trucks. The part number is 117. You can only lift the front about 2 inches max before having alignment issues.

It wasn't enough because the 822 is for 351W. IMO you would have gotten about 1/2" more if you used the 844 which is for the 460.

I really like how that sits. I have thought about lifting my truck a tad more and going from 31 10.50 to 32 11.50 after I get around to swapping the motor. I'm curious of something though. If the front is lifted 2.5 inches, how is it that the rear has 2 inch blocks and it sits nearly level. If it was actually only raised 1/2 inch different in the front it would still be nose down. Are you sure the rear blocks are 2 inches thick? Usually I remember a 4 inch lift being 4 front and 2 rear. Do you a part number or link for the kit you have?

Here is mine with Superlift 117 that raise the front approximately 1.5 inches or so and 31 10.50s.

Thanks, Texas. Yours looks nice too.

So I’ll explain how the lift gives 2.5, per your questions. The rear blocks are 2in and the front springs provide 3in of lift, for an overall average, of 2.5 inches. 4in lifts typically come with 3in blocks for the rear, and springs that give you 4in of lift in the front.

I too had considered 32x11.50, but 11.50 is a little wider than recommended for the stock 7.5in rim. I love the bullet hole stock rims. I think it’s the best looking rim Ford ever put out. Another thing is that BFGs tend to run small. For example; the 31x10.5/15 measures anywhere from 30-30.5 installed. The 32x11.50 is 31-31.5. I wanted the 10.50 width, and a true 32in height. BFG are what I wanted to stick with, so I went with the 33x10.5/15.

The 33 10.50 is a cool size. My buddy put some on a restored J10 a few years ago.

Did you have to go with different shocks or change anything else with these?

Nope. I'm running Monroe Gas Magnum for a stock truck. I have always run stock shocks on 3 different trucks and so have a couple of my friends that did the same thing. With these or with the Moog F250 springs you will need adjustable camber eccentrics for the upper ball joints to get the alignment correct.

Someone mentioned that tire size 33 x 10.50 x 15 will work on stock height. No level kit or lift kit required. Is this true?

Depends what you have. I have 33x11.5 and only slightly longer springs in my 91. Rubs, but plenty drivable.
