Question Custom rear susp. mounts???

Hey everyone,

I was wondering if anyone had some input...we are building a Disko for the Outback Challenge and on the rear suspension I am trying to decide if I should go with the HD RoverTym upper mounts and lower loop adaptors or If I should take the shocks from the axle up at and angle to where the wholes for the self leveling unit mount on the center of the frame. I was just going to make my own upper and lower brackets with some plate and grade 8 hardware.

Can anyone comment on this giving more/less flex or a better/worse ride? I would appreciate some opinons.

BTW, we are running 14" SB Billsteins.

Thanks!

You mean like this? If you do it rocks. It provides a much better ride than the standard shock location by fighting body roll. It will give you more travel too. Mine is limited by the retained springs. The way the factory and the aftermarket mounts the shocks in the rear is odd, it does nothing for body roll or for load control, they should angle backward to accomplish anything. Good luck on the 14in shocks in that configuration though, I have a 3in lift back there and can barely fit 11in travel shocks. It doesn't matter, at that ange every inch of travel in the shock turns into about 1.8in at the tires. I have over 18in of truely useable travel. I had a custom crossmember made, I suggest you do as well instead of mounting to an existing structure. Also, this gets rid of the retarded lower shock mounts, also known as rock anchors.

Talking

David I think we were talking on Pirate about this YES? Could you forward me some more pics and possible details on that cross member? I had planned on doing exactly what you have done.

Thanks!

David that setup looks a bit like what I just bought from Matt... NSO rear shock mounts (I know yours are custom).

My buddy cliff sports them, you can sort of see it here:

KC Carpenter, http://www.neversummeroffroad.com He might be who you were talking to jason, I think he's on Pirate.

There's an old link to the page, but I can't get the pictures to load:

KC built mine too! He just had to make them a little differently due to the military chassis and the custom gas tank. NSO is no longer selling any products last time I spoke with him.

BTW Dave, you talking about all that flex is making me happy I got them. What shocks to you run? I was told the Rancho 9114 works well, I think that's like a ~ 9" travel shock. I was thinking of using Bilstien 5150's though.

I have the rear 9in though so I can't really tell you what to run as far as shock lenth. I have ranchos, don't even know what kind. The system is good, I can droop about two inches below the bottom of the sliders, which hang 1in below the stock sills, with 37's. I still want to get the SG type spring drops, for a few more inches. But I am waiting for someone else to make them so I don't feel like a whore. Hint hint rovertrax.

I have the same mount made by the same person, yes it is the Rancho 9114. As David said a 14" travel shock isn't necessary and won't fit in this configuration. I had to turn the shock valving to it's stiffest setup to get to ride like it did before. Also put the studs or bolts on the upper mount in double shear, I've bent both studs on my upper mount in single shear. You will also have to loose the stock exhaust from the muffler back.

Tis,

What is double shear or single shear? Different bolt strengths? It came with two uppers, although I've got to get rear studs. How different is the exhaust routing? I've already got a flowmaster with new pipe back and I'm worried I'm going to have to replace it again.

thanks,
Dave

I mean there's the homepage but nothing clicky.

Once upon a time I remember there was a working pic section and other stuff...?

Or it's just me that I'm dreaming as usual...?

There is no more NSO. KC runs a LineX shop now. He only does stuff for friends I think.

Dave-

Double shear relates to the way in which the mounting bracket distributes the force applied to the bolt holding the shock in place. In this case you have the mount with a bolt welded to one end of the bracket and the shock mounting perpedicularly to that bolt. As the suspension compresses all of that force is transferred to the point where the mount and the bolt holding the shock meet, singe shear. If the mount had a C-type bracket with a tab for the bolt to pass through on the other side, it would take some of the load, double shear. Another way to visualize this is imagine the shock mount eye with a tab from the mount coming down on either side of the eye so that the mounting bolt could pass through one tab, through the bushing, out through the other tab and fastened with a nut.

As for your muffler setup all you will need to do is cut off the exhaust pipe just past the muffler. You may want to turn the tip of the pipe down like David's picture above.

You have two uppers because one set is for the shocks and the other set is for limit straps if you choose to run them.

Tis

Hi David,

Any chance of dropping those pics on the forum. I'd be most interested too as it will complement my 3 link system.

Cheers,
Andy
