Hey guys,
As the weather is getting some what nicer.. I will be thinking of putting a dana 60 under the front.
I am stuck to if I should slap some leaf springs up front or just get some 9" Coils...
How much fab work would it be to put leaf springs up front?
Cheers

All you need to hear is, USE COILS, FUCK LEAFS.

coils, build extended radius arms and new mounts and beef up the panhard

what year D60 do you have?
we have an 88 that we are doing extended radius arms on, we used the portaband to trim the cast housing back a bit to make more room for the weld on wedges
frame area around the panhard needs help, tie it to the far rail as best you can

9" coils are off the shelf items, cheap too.
got mine from broncograveyard

Hey mj I was thinking about bronco. How are the coils holding up. Are they heavy duty? How much was shipping.

I was also thinking of doing a 4 link set up with coils. Any thoughts?

you would have to do a parallel 4 link and pan hard.
If you do a triangulated 4 link, you will have bump steer.

personnaly i'd to a 3 link up front.

It would do a paralleal 4 link. Its a big debate as I'm not that good in the designing department. Think 10inch coils woud be kinda cool. In all 4 corners.

check out my dana 60 that is coil sprung with stock radius arm style :)

I dont have a truck on the road now
I really liked the 9" coils, not too soft but way softer then the 6" that were in it when I bought it. they were rated at 460#
only used the 9" springs for a year or so and it was a hack install :)

:confused: how do you figure? unless its not built right or 10 feet in the air i dont see why bump steer would be an issue

a properly triangulated 4link moves up and down and not in an arc.
when it moved up and down correctly your drag link will essentially get shorter during down travel and longer during up travel, creating bump steer.

if you can get your drag link perfectly level to the ground it will be minimal, but its hard to do.

you get bump steer with leaves too

Seems like you get a bump steer with just about everything in away....

depends on how its set up

that is an accurate statement
if it isnt from the linkage it will be from the wheelbase changing as the axle moves
just come down to getting it as low as you can with the parts you choose to use
