Dropmember in a 69 C10

[watahyahknow]

hmmmm made me get an idea : if you make the backhalf out of boxsection you could use it to dump the exaustgasses behind the rearaxle without the usual problems getting pipes over the rearaxle and past the gastank (just an idea prolly not possible because of vibrations and stuff )

I wouldn't be concerned with vibration. However, from a practical standpoint, I wouldn't want to run exhaust through the frame channels because of the condensation inherent in exhaust systems. That condensation is what eats through exhaust systems... which is not something you want happening to your frame.

It could be pretty trick to do something like this, but like XXL mentioned, moisture is the enemy! The inside of the frame rails could be coated and sealed to prevent any moisture from damaging the integrity of the frame rails.

will this back half be set-up for a corvette IRS?

There will be a C4 version available shortly. The previous pics are for the straight axle version. The differences between the two variations are: the C4 back-half will not kick up as high as the straight axle version, the locating links will be a bit different, and the air suspension will be set-up with a rocker-arm and push-rod assembly on the C4 version.

Any new pics of the rear setup? What type of bag setup will it be? Does a 4 link setup work better or ride any better than a 2 link? Any idea how much?
Also started working on my dropmember install, I never got instructions so I used the Classic Trucks tech article! Any word on my rack? Rack notches- Heims? Thanks for all your help Nathan!

I just pick up an the new issue of classic truck. I see the the dropmember made it in the tech section.

would that crossmember raise the engine enough to run long tube headers and still lay?

I don't think so. How far below the framerails do the long tube headers set on a stock crossmember?

The Big Block mounts are done. I shipped the first Dropmember BBC combo out this week. The motor mount tabs for the BBC set up 3/4" higher than the SBC and the mounts themselves are all the same. I am yet to mock it all up in a cab to see exactly where the fit issues lie. I am assuming some slight mods to trans tunnel where it meets the firewall will be needed (maybe 1/2" of clearance trimming) it might fit without slight trimming, but I am uncertain yet.

that back half is sweet

i got one question does a 5.3 with a whipple charger fit with the drop member with stock hood?

There should be no hood clearance issues with this combo. You will however need to ditch the truck oil pan and get an F-body pan and pick-up tube.

Nathan,

What are my options as far as control arms? Should I order Djm's and have you modify or do you have another solution? The tire I want is a 285-35-22 which I beleive is close to 30"

thanks

Don't buy the DJM's ... I will do some thinking and see what would be best.

That's a pretty wide tire to run up front.

PB,

Please allow me to ride the coattails of this discussion and ask if either of those vendors (UniSteer or RockAuto) can provide a rack-and-pinion for my '72 Suburban?

At this point, I'm leaning towards a C4 Dropmember with BBC mounts, but due to the weight of the vehicle, the rack and pinion unit is still an unresolved issue......

I don't have accurate corner weights (yet), but I know that the overall weight of the 'Burb is right around 5200Lbs, with probably 60% of that over the front tires.

Ideas?

The C4 rack would be the solution. It is a beefier unit than the MII and I wouldn't hesitate putting it on your BBC Burb.

I wouldn't worry too much about the MII set-up either... I just have to follow along with the manufacturer's specifications.

<<<<<<< perks up would it work on a dualie too ?

[64shortc10]

Any new pics or updates on the 69? I should be ready for my control arms soon and those new upper bag mounts! Any idea if a 05 C-6 rear end will work with the back half setup you have? My brother in law came up on a disc to disc rear end that a customer was complaining was making noise. After installing a new rear end the corvette still had the noise so there was nothing wrong with the old rear end. So free rear end for me if I want it. Let me now if it will work

Looks like I am moving to Chandler, so I think I will bring the ole 67 in for a front and rear suspension!! Can you PM when you get a chance to talk about some prices. thanks

[SantanaCustoms]

any new pictures of the rear sections

[Dizzy]

WOW... I feel like I just read a book! Very good stuff here, I just might have to get me a C4 Dropmember now. I am also looking forward to the finished pics of the back half.

[PBFAB.COM]

Finally have some updated pics of the upper shock mount to be used in conjunction with Air Ride's Strong Arms (new design: shock tab located on top of lower control arm). The inner frame brace for the shock mount is tubular in the pic, but will incorporate plate gussets similar to the inner frame plate of the Dropmember.

On another note: Due to some difficulties in coordinating with outside vendors on steering components, I will no longer be offering the Dropmember with steering components. I will happily assist in providing customers with part numbers and contact information fo the steering components. I will however, be able to provide the Dropmember with Air Ride Technologies components, and Slam Specialties Air springs.

This may sound dumb, but why are they so big?

And are these your shock mounts or air rides?

That is as small as I could make them and still have them work! Maybe the camera has added a few inches? These are MY mounts to be used in conjunction with the new design Strong Arms.
