Kinda looks like you have all of the information that you need. Since there is a carrier break for the D44, you will need another carrier if you chose to use the lower 4.10 gear. Oh yeah, 4.10 is considered a lower gear than the 3.55:1, even though it is numerically higher.
The 9 inch does not have a carrier break, so the new gears will bolt up to the existing carrier.

You don't have to throw the baby out with the bathwater. You only need a new carrier for the front axle. They run about $60.00 to $100.00 (US) for an open unit.
m78:
The D60 carrier breaks are 4.10, and 4.56.
If your 60's already have 4.10's, they will accept 3.54 gears.

Gear ratio
Hi:
Want to know how to increase the turning ratio for a 1973 4X4 F-100. I bought already lifted to 4" or 6" hight but the gear ratio was reduced because they didn't change the bars I think. Want to know the items or components needed to compensate for the 4 or 6 inches lifted. If someone can help.
Thanks

The question you are asking is a little vague and I am having a bit of difficulty understanding it.
Would you please try to re-word your question and perhaps be a little more specific. I am not sure if you are talking about gear ratios or steering, or radius arms.
Should also create a completely new thread. Never too polite to hi-jack an existing one, and you will recieve much better exposure for your specific question.

bars?? there yellow? my kit had drop pitman arm dorp radius brakes, new c bushings and blocks and add leafs and shosks, so bars i am lost on. but if you are wanting to lower the gear ratio the same as me you need to know what ratio you have now. i know the taller the tire it makes your gear ratio higher. i think 4wheelparts.com has a chart on that issue you are talking about in the tire section.

Steering radius
Hello all:
I think I'm in the wromg forum. Sorry for being an intruder in this "gear" forum. (English is not my native language and confused "gear" with "steering") The problem I have with my F-100 is related with steering vs lifting. The problem is on the front steering bar that are short for the hight the vehicle was lifted. Because the previous owner lifted and remain with the same bars, the steering capabilities was reduced. The pick up need more area to make a "U" turn. I'll continue to looking on this web page to find a forum related with this situation with my "new" 73' F-100 4X4. anyway if someone with more experience in this forum knows which is the one to participate I will be glad to know. Thanks for your attention and patience.

You are alright, we can help. Just needed to know clarify a little. The steering linkage you are refering to is the Drag link. Your truck should be a coil sprung front suspension with an inverted "T" steering design.
Couple of things you can do. Drop the drag link down by adding a drop pitman arm. This will allow the drag link to work at less of an angle and it will not be so short, so your turning radius will return.
Do watch the angle of the trac bar. The angles of the drag link and the track bar will also have to remain the same, (may need to add a trac bar drop bracket) or serious bumpsteer will occur.

Hi 75F350:
Thanks for your advice. But because this specific forum is not about steering, how can we continue this comunication? Don't want to deviate the original theme. You can also send me a private message.
I think the pitman arm is short for the hight lifted. Need to identify which part is the drag link. Where do we find a picture of the front of the 4X4 axle?
Please open a new forum to continue this comunication.
Thankyou,
Yellow Ford

75F350 and any other may help:
I move my concern to "Steering" forum. It is more related to the problem I have with my 73' F-100 4X4. Please go there to continue explaining how to increase the steering radius after lifted 6".
