4wd conversion

I am in the planning stages of a 4WD straight axle conversion for my 1995 Chevrolet fullsize 2wd pickup. I have everything figured out except for a few measuremnets I need. I need the front spring pad center to center width of the springs in an older model chevy 86 below straight axle truck and the distance from center of front spring hanger to center of rear spring hanger in the front. This is so I know where to place my spring hangers. I already have the center line marked on my frame. Just need to know where to stick the hangers. Also, any suggestions you may have on this project would be greatly appreciated. Also, in stock form on the older straight axle trucks, are the front and rear spring hangers on the front of the truck level front to back with each other or is one higher than the other and if so how many inches?

Re: 4wd conversion

When are you planing on doing this project? and do you have any idea how long its going to take you?

Like Mike said, someday I to am planing on doing the conversion but my truck will probably be the 90 2wd truck I have right now. I am more than likly going to be going with a GM Dana60 front and 14-bolt FF rear. 205 T-case, TH400/475 transmission and a big block to make the power. Lift wise I will only be running 35's and there will be about 6"+ in the rear and no lift up front. There won't be a front bumper so I won't have to worry about that rubbing and there will be some chopping of the fenders too. The back will be a SUPER HEAVY DUTY leaf spring pack that will handle tons of wieght and up front will be coils.


Well, thats most of what I am going to be doing with the truck, any more questions feel free to ask...Ryan

Re: 4wd conversion

Well, I am goinng to take plenty of pics. Probably start it around christmas since I will be on a 4 week break from college. Around December 15'th or so. I have everything planned out except the measurements I need which I posted on my orgional post. I plan on using GM Dana 60 front, Corp 14 bolt FF rear, ARB in front and Detroit in rear, NP205 and a 4L80E transmission. I was origionally planning n 5 link front and rear but figured I would loose to much ground clearance with the center secion in the frame that the links would tie into. I am using 4 inch springs in the front with Revolver shackle and 4 inch rear springs with shackle reversal and with Revolvers. With shackle reversal and 4 inch springs I will have 8" in rear. My front spring hangers will be 4 inches lower than rear so I will have a total of 8" in front and be able to use softer 4 inch spring to achieve the 8". I am getting all drivetrain equipment from Boyce Equipment. If you are going with no lift in front you will be having a major problem with the engine crossmember coming into contact with center section of Dana. With 8" lift I will have approx. 8 inches in between of dana and factory crossmember but I am going to build a tubular crossmember that is much shorter.

Re: 4wd conversion

ummmmm, havn't seen or heard of that problem in any of the other setups that I have seen like this. By the way, this truck will be for pulling and will see nothing other than a 300' track about 8-10 times a year. Im even considering running a spool in the rear and a locker up front, who know's maybe even a spool up front too seeing I will always be going straight anyway.

Good luck on the conversion though....Ryan

Re: 4wd conversion

You mentioned you were going to use coils in the front. How are you going to attach your dana 60? Link setup?

Re: 4wd conversion

Im not totaly sure yet on how it all will work and I am probably going to be having someone else that has done alot of conversions do the work. This guy has built 3 trucks and he is pulling in all 3 classes and is on top of the Ontario circut, he know's what he is doing.

Re: 4wd conversion

Thanks for all the replies and information so far but no one has answered my question about the measurements I need. Also, I was origionally planning on using revolver shackles in the rear along with my lift springs but I have started hearing bad things about them specifically about hill climbing. So, what can I use to increase the front and rear articulation of my truck. I will be using BDS 6" lift springs front and rear.

Re: 4wd conversion

Also, on an older style non-lifted straight axle truck, what is the distance between the center section of the front axle and the closest thing on top of it that it could possibly hit? I figure with the planned lift I will have 6 inches above my dana 60. Is this sufficient?
