I've been debating going bigger on the lift on my truck.

I currently have the Skyjacker D25 springs up front.

Would like to add a 2" spacer and make it a 4.5. Then add the 2" add-a-leaf in the back. Thats the cheap $150 in parts

The other part is track bar and control arm lengths.

I see DT makes arms that are a 1/2" longer longer. Is that enough for that big of a lift? Doesn't seem like it. Using some basic geometry and the triangle rule, it seems like an 1" longer, give or take would be more inline.

I priced a BDS link kit(arms) for their 5" kit and it was $600. Seems a little spendy.

Obviously I can get the nice DT track bar. Not worried about that.

Worried about getting the control arms. I see Solid Steel has adjustable arms, but are they adjustable length wise?

Anyone else make arms? Can you get just the arms from Tuff Country?

How much longer would the arms need to be to work with a 4.5" lift?

Thanks guys

 

I have the DT 1/2" longer arms with 4.5" of lift.
Seems to be just fine.
Call DT for more info.

Do you have any pictures?

Are you running 315s? Any rubbings?

I don't rub now, except on the lower control arms at full lock, but its close.

I am putting on 16x8 wheels with 4.25 backspacing and I'm interested to see if it rubs or not.

And, it would be nice to put the DTs on now. Then still be able to use them if I go bigger.

 

I run the Hummer wheels with the BFG 315's that came with them.
I don't have any rubbing.
I think the Hummer wheels have more back spacing than your 4.5
I don't know why they don't rub?
Maybe it's my 4.5 lift?
Maybe it's the longer arms?
I dunno....

what does dt stand for? I want to look them up and pick up a set for me.

 

DT actually stands for David Turbyfill, the guy that runs it. His site is dtprofab.com.


The 1/2 longer arms will work great with 4.5". I've set up several custom suspensions using these CA's, they're as close to bombproof as you can get. If you want to go higher than that, you'll need to do long arms anyhow. I was going to do these on my truck until David talked me into test bedding his radius arms....now I wouldn't go back to 4 link on a bet.



The RA's are spendy though and you have to cut off the lower CA mounts.

At 4.5" you'll need a track bar drop bracket or an aftermarket track bar.

 

Hey cowhand, why would you not go back to a 4 link? Even a long arm 4 link?
