Mike. I went out and crawled under the three various dmax trucks we have here at the shop.. Crew short was 8 hole hanger, sclb was 10 hole, cclb is 10 hole also.. It's mg understanding the short bed trucks use the 8 hole and long use the 10 hole

That would be correct. But there are 3 hanger types. I think the long bed has two variations. Whereas the short bed are the same regardless of cab config

When you guys research the McGaughys front leaf hangers the CCSB and the SCLB trucks use the 6 bolt hangers the CCLB 2500HD 3500HD and ECLB 2500HD use the 10 bolt hanger.

I have a set of McGaughy's drop spindles (picked them up for less than 1/2 price on craigslist) and will be purchasing the front leaf hangars in a month or so and the truck will be down for about week. Leaf spring bushings, UCA, LCA bushings and the previous items mentioned using this to remove the bushings, already tried it on set spare set of leaf springs...

This was the best lubricant I could find to keep the threads from galling. After I removed one bushing full power with my 1/2" impact the threads were barely warm..

Missed one set for the front leaf hangers, Wisconsin Hick has 6 bolt FRONT set on his truck, so yes there are 3 different hangers for the FRONT 6-8 and 10, they only count the ones that bolt to the frame.

The first one is a 2500 non HD and my ECLB has the 10 bolt hanger

woh woh now guys, im not implying he set it up wrong. just asking cause i couldnt remember if it was 2wd or 4wd and had some more questions. :D

Eric, what was happening when you had the rear end setup really soft? i think you and i talked about this in one of our convos before but i cant remember.

We did but my issues was up and down movement as well as side to side. I also couldn't get enough pressure on the leafs with the Caltracs to stop the hopping off the line. I was going to try 3 leafs but didn't want to deal with pulling them and adding the 4th if needed so I said heck with it I'll run 4.

Yes there are a few options I called them if I remember correctly. It took about a month to be sure I had the right ones.

Yes the ass end sets good. Still have some fine tuning on the shocks. I think I have the rebound set correctly just need to work on the compression. I think it needs a little more to slow the settling in off the launch. I wish I could get someone to video my launch from outside the truck to see what it's doing.

I'm sure I will.. Mine won't be at your power level but it'll be good to have the setup if it ever makes it there

I know the feeling of a soft 2 leaf rear that's what I run now. Doesn't hop alot in 2wd just spins on the street on st2s. Do u think the hopping could be from your more level spring angle you have with the drop hangers? I know the softness was probably the root cause but I wonder if that helped or hurt u changing the angle of the leaves?

Eric, I have access to a Torchmate, could you measure the horizontal and vertical dimensions of the Caltrac pivot at the front leaf and post them or anyone with a set of Caltracs....

I can this weekend if that works? I would two jobs so not much time other than to shower and sleep Monday - Friday.

Last year when I had the 2 leafs it just had the drop shackles. Not sure if changing the front hanger height would have helped or hurt that issue. I had to crank my Caltracs down pretty good to keep it from bouncing this year also. With my ST2 and my now 420's I could spin on the street just fine but when I put the slicks on it's a whole nother ball game with the bouncing.

Have u tried running one of the higher holes in the caltrac brackets?
