Hello,
I have done a quick search on here, but most posts lead to leaf TTB setups..
I am looking at the options of fitting 35" tyres to my F100.
Its a 85 model, twin shock and coil front end. Dana 44, with a F250 Dana 60 rear.
Currently have a 3" body lift and 33" muds.. but really want to go bigger.
Would like to get away with not having to cut my guards as I just resprayed it.
Has anyone here lifted their trucks of this configuration to fit 35"s? Any pics or info about?
Thanks heaps in advance.

 

These trucks have been around awhile now, really the only way to lift it by the suspension is to buy a kit. This is true for the leaf sprung suspensions as well as the coils like yours.

Your front suspension is a twin i beam design. It's attached to the frame in the middle and in the back on the frame under the doors. These attachment points have to be lowered and then taller springs installed. This then throws out the steering linkage out of wack, so a dropped pitman arm for the steering box is needed. Then longer shocks. You can put simple blocks with longer u-bolts in the back.

Wait a minute; I see you are from Australia. I am assuming you have the same suspension setup that we use over here, but you may need to take a picture so we can verify what you have.

 

Thanks for the reply Franklin!
I can never remember what the difference between twin i beam or TTB is??? I ended up assuming they are the same thing?
Your description sounds like what I have.. I will take some photos of my setup after work and upload them..
Would you recommend a kit or supplier? I imagine that I will have to purchase from the states... Which is no biggy as everything is stupidly overpriced here anyway.
I'm happy to do welding, but would prefer a bolt on kit that would cover all components of the kit to get proper drops/angles to avoid bad camber or excess stress on the gear.

 

Yes, I'm thinking he has 4WD on that thing.

 

Yes definitely is 4wd

 

Twin I Beam is the 2WD suspension. It uses solid beams with an "I" cross-section, hence the name.

Twin Traction Beam is the 4WD version. It works much the same as Twin I Beam, but instead of solid I beams it has stamped steel channels that provide a place to mount the diff and run axle shafts.

 

Perfect explanation NS.
Out of all my readings, that description is the most informative and helpful I have come across.. thank you

 

Do some research and find the kit that has all the pieces at the cheapest price. I have no recommendations, I have never bought one my truck already came with a lift under it. just make sure you are getting;

The drop brackets for the center pivot mounts.

The drop brackets for the radius arm mounts under each door

Dropped pitman arm for the steering box

Longer shocks.

Your best bang for the buck is going to be a 4 inch lift. 6 inches is usually a little to high for most uses.

Some kits will have longer brake lines, but if you re-mount your brackets and bend the hard lines a little bit, you can get by with the stock brake lines.

Most of the cheaper kits will give you blocks and u-bolts to lift the rear. These work fine, you may notice a little axle wrap but you can live with it. You can get lift springs for the rear but they are more expensive and the ride can be a little stiff.

 

Thanks for that Franklin
I 'll have more of a look around.
Cheers
