leaf or coil?

Post by OCD4B2 »

I went with coils and was seriously considering doing coils in the rear too. Coils is a much easier setup in B2s since the buckets are already there. I even had a Dana 44 HD that was out of a F-250 and was originally leaf sprung. I just bought the weld on C-wedges from James Duff and welded on it to be able to use F-150 radius arms. Depending on how high you want it and how tall of springs you use you can use the stock B2 radius arm mount moved back to accomodate the longer radius arms, or if it isn't sitting quite so high you use the mounts from the F-150.

Go about 1/2 way down the page and look for the axle wedges.

Those are the one's I used. Just welded them right onto the D44 that I got from a 79 F-250. Worked out great.

Well the coils bolt to the radius arms. If you dont have the radius arms and buckets goto a junk yard and find some. Or you can probably make your own if you know what they look like.

if you get radius arms get the perches along with them......there are two different types of perch. one set has the bolt holes closer then the other, but other then that they are identicle.

Srry i realize this is a little off topic, but would it be any more difficult swappin a D44 from an 87 F250 into my bronco II as opposed to the late 70's D44's that others seem to be using?

if you do any rock or steep tail running at all you will be so much happier with a sas hp d44 than a ttb d44 from a later f150. (btw most f250s ran d50s not d44s) Considering the amount of work and welding involved I would say it would take less work to get a sa d44 in there than a d50. less complicated, simpler steering, and much better flex at the end. I have a d44 from a 87 f150 if you really want to go that route, but I would highly recommend that you look into the sas d44 first.

for a d44 get one from a 76-79 f150 or a 76,77 bronco(lp) 78,79 bronco (hp)
the f150 is high pinon

for a d60 get one from a 77-79 f250 camper special or f350
they are all high pinion

also for d44s early 80s jeep wagoneers work well too.

thanks very much thats exaclty what i was looking for, however are the wheels the same pattern between the F-Series truck and bronco, so i would be able to mix and match the front and rear? other than that im assuming they are all the same width give or take

The high and low pinion are what position the pinion are coming out of the diff. A high pinion makes for better angles, as the driveshaft does have to drop as far from the transfer case.

Some say the high pinion is stringer then low but I have no knowledge of this, as I just barely have experience w/ a d44.
