DOes any one know what the metal that is used for the front i-beams is, cast steel, iron or forged... email me at sfigueiredoNo Email Addresses In Posts!,
I have a 91 chassis for my 66 f100 that I am in the process of making a new suspension from the ground up and I am going to have the ibeams welded for better angle etc.

Ned to identify axle code

My shop manual does not list an axle code 12. it lists a 13 as 4.11, a 14 as 3.00, a 16 as 3.50, a 17 as 2.47, a 18 as 3.08 and a 19 as 3.55.

I found listing that states a code 12 to be a 2.73 ratio. Not sure if this was a front or rear, or if it even makes a difference. 2.73 seems to be a bit low for a truck.

In my 1994 F-series owner's manual axle code 12 is listed as a rear axle 2.73:1 ratio,non-limited-slip.It should be a 8.8" Ford axle with a 3,800 lb. capacity rating.

2:73 with a Mazda 5 speed tranny? That cant be, you would be doing 60 in first gear. I geared up my truck from 3:55 to 3:08 do to rear end blowing out. I have to down shift damn near every hill i klimb. I run 60MPH at 1800 RPMS.

Ned to identify axle code

I find it hard to believe myself... i get to 2000 rpm at 10 mph and have to shift to 2 nd, now i put on 31' tires, like i can got up to 15 mph but I have a harder time to get to 65 mph, at 60 mph i get 2000 rpm on 5th.

What would be my best be to get great accelaration and higher top speed if i stick with 31's ??

thanks
