does the xmember mount on top of the top frame rail??? i know you said its designed to have a 1/8" clearence, between the cab and top most point of the xmember, and putting the xmember on-top of the frame rail, vs. on bottom (of the top frame rail) would take up that 1/8".... does that make sence? nate, you have a install pic?

All others go under the rails just like factory.... I would assume PB's do as well.

correct, it sandwhichs the frame-rails, meaning the xmember goes between the top and bottom frame rails... PB xmember doesnt sandwhich the rails like this. it either has to mount on TOP of BOTH the top and bottom frame-rails, or mount on the BOTTOM of BOTH frame-rails..... and when talking to him he said it was designed to have the 1/8" clearence, so if it was mounted on the BOTTOM (when designing), and i mount it on top, then i would be realllly close (if not hitting)....

Don-

No drama worries!

Yours mounts just like you have it in your build thread pics. The top mount will be on top of the rail, and the bottom mount will be on top of the bottom rail. I have been experimenting a little! With this mount design, you could gain a little additional clearance IF needed by mounting the x-member mounting tabs under the top rail, and under the bottom rail... Hope I made sense.

Nate, those look great. I have seen your products around but I did not know you were on this site. I am on a similar path of R&D as you were, but not for production more for personal use. I am putting the whole suspension system on a ford 9" rear and would have to tweak every thing you've made, other wise I would be in line for a set myself.

As long as the axle brackets are the truck-arm type, PB's stuff won't know whether it's a 12-bolt, 9", or Dana. What else are you 'tweaking'?

[Dinos63]

you almost ready for the panel?

[panhandler62]

A pair of heim joints arrived over the weekend... I'm ancious to see the rest. lol Poor thing has been sitting out there so long doing an impression of a garden sculpture that I am super jacked to get things going on it finaly.

It was a busy weekend getting some home repair/upgrade issues sorted out, but I did manage to get one a-arm cleaned up. Gotta love the smell of oven cleaner when you get too close hosing the things down. lol

While waiting for the rest of the suspension parts... Here is what $40 will get you o eBay if you hunt around enough:

That's a big intake for a C20 (heavy) truck. What's the intended RPM operating range? What CID?

I am running Bilstein coil overs behind the axle. So no spring perch, and no bend.

Yeah.. it is pretty big.

She has a 350 with a 4sp (3 +1) and a fairly low rear. Before taking it all down I never used 1st gear. I do know I'll sacrifice some off-idle but with all the gears available it won't be hard to keep her up over 2k.

The biggest issue is that I will probably need a vacume can if I want to run power brakes.

Let me know if you need some help on rounding up some parts. The spherical joints I am running would be perfect. I can get you the joints, bungs, and machined spacers if you need them.

[Mike Bradbury]

Nate,
Well shoot, I just ordered the Del-sphere joints today. But they don't come with the spacers, or the bushings. I was just going to machine them, if you can get me a set it will save me some time. What do you charge for a set? PM will do if you don't want to talk prices over the air.
Thanks
Mike

OK, bear with me here. I have a leaf spring truck, so this is why I'm asking. How low will this setup go with the 3'' TA's? I know about the TA's hitting the frame, but I don't think I've ever seen just how low a trailing arm setup really goes. I would really like to do this setup vs. a rear DM. Laying frame is not a priority, nor is running 24''s. Just nice and low on my 15''s. I already have a notch big enough to clear anything, so that is not an issue.

[SCOTI]

I know the PB arms will offer greater drop vs. OE arms because of the smaller diameter tubing vs. the OE's squared I-beam style of contruction. I can't offer how much more drop is available because of this difference in construction. Nate hasn't mentioned it in our discussions, but maybe he's looked into this & can share the difference.

[Rochlow]

I think I got some of those Heims joints this weekend too..

[lowdownstar]

Anyone done installing the trailing arms yet? I am having a little trouble with clearence, i only have an inch of suspension travel before i hit the frame. It has a small notch but i think i need to go bigger on the notch. I guess what i am asking is, can i go with a bigger notch and keep everything else the same?
If anyone has some pic's of how thier project is coming out that would be great as well.


Thanks for your help


Ray

[lolife99]

Ray,...
Do you have any pics?
I think some people have used a step notch. (either at full height or cut down a little)
Either way,... the location where the frame crosses over the top of the trailing arm,... is the limiting factor.

hey Panhandler62

OMG I hate those Rivets!!!!! i had to get my off with the bed and cab still on the truck and me on the floor. I used everything i had to get them off, grinder drill and air chisel

Hey Keith sorry no i don't have any pic's but i will take some tomorrow. The thing i was worried about is if i go with a taller notch am i going to screw up where the shocks mount or the bags? I don't care to lay frame but with the drop member up front i can't leave it to high, It would look stupid.

Thanks Ray

[lolife99]

Can you say,... Dropmember #2?
That would make your truck!

[lowdownstar]

LOL thanks Keith Can you say pour man! empty pockets. I should of left it stock!!!! LOL



Thanks Ray
