Dropmember in a 69 C10

[jimmydean]

Outstanding!

My friends '77 GMC step will be ready for a C4 setup very soon. I would like to do a full front and rear C4 if possible. Look forward to the updates.

Nathan,

I'm sure getting Horny for some new install pics and progress pics on the 69!
I'll need to work some overtime so I can buy the shock mounts and hood hinges at the same time!

We bought a dropmember for our shop truck. Looks great Nathan. Its mocked up in the truck now. With the Z ed frame we could lay on 24s at least. Think we're gonna ditch the drop spindles. I'll try and get some pics this weeekend. Unfortunatly the trucks not in the shop due to space shops full of customers stuff.

[pissonNOS]

rob I'd like to see those pics might give me an idea how low id be with just some stock spindles yet mind you im not Z'd but still pics are always nice

That highlights all the minor design changes that have been made.

I will be doing a Dropmember/KP six-link with watt's link combo on a 78 coming up here shortly... I will be posting install pics once completed.

I should also have some pics of the C4 back-half and the full C4 chassis for the 63-72 trucks posted up within the next week.

WOW is all that i can say still saveing money here

your work is amazing. cant wait to see the write up

[Frizzle Fry]

Has anyone told you that you do nice work? Outstanding!

[blaznhot_23]

Sweeeeet

[72CSTC5]

I have said it once and I will say it again, that piece is a work of art. Makes me want to get back on the blazer just to put that in there.

[pissonNOS]

would it be wrong of me to make a poster of your welds for inspiration haha

[BigShoe24]

I just ordered a X member from Porterbuilt!!! I cant wait untill it gets here, I will try to post some pics as soon as it gets here. My build thread is gone so I guess I'll try to post them were there are already some pics of another install.

Is this yours? http://67-72chevytrucks.com/vboard/s...d.php?t=235617

[BigShoe24]

DM310, yeah sure is. I looked forever and couldn't find it. I really appreciate it.

This crossmember is awesome along with some really good craftsmanship (hard to find these days) Also for the non fabricator it gives them something reliable that wont break, Ive been in the truck seen for a while in fact I used to have my own shop until some things fell through with a bad business partner and the hacked up stuff Ive seen makes me wonder how somethings dont fall apart above 10 mph. This is quality. For me the time it saves in fab and engineering is well worth the money plus this thing solves two problems I already have, one someone installed some aftermarket tube a arms on my truck around 8 years before I purchased it and the thing is so low the a arms bind on the mount for the lowers that replaced the crossshaft and u bolts, two is I installed a GMPP fuel pump (because it was laying around un used) and it was so big I had to cut the motor mount mounting plates to clear the pump and the inlet fitting. Again this thing is awesome keep up the goood work and sorry for ranting on!!!

[gringoloco]

I've searched around and can't seem to find what exactly must be done to the stock control arms when used with a dropmember. I know slight clearancing and some way to mount the bag, just looking for specifics.

PB- do you have a pic or a more detailed explanation of what is involved? Anyone else run into this yet?

btw- my truck is a '70 with an '84 crossmember/suspension if that makes any difference. I seem to remember something about the '73-up arms not needing clearancing...

Thanks -Chris

Chris-

I have a minor design change coming in the near future that will eliminate any clearance issues with the 63-72 lower control arms. I will see if I can get a pic within the next few days of the current "clearance issues" on the factory arms. Until then, I will do my best to explain the area of concern... The 63-72 factory lower arm design has a large u shape, at the edge where the cross-shaft mounts through it. If you look closely at the current lower control arm mounts on the dropmember, it is a large billet block, and very square. The lower edge of this mount will contact the back U portion of the lower control arm next to where the cross-shaft slides through. It is necessary to trim the lower control arm at this spot to allow it to swing through its range of travel without contacting the billet mounting block. The 73-87 lower control arms do not have this large arc, but are more squared off at the edges where the cross-shaft slides through, and thus do not need any trimming. The other mod, for all factory lower control arms, is going to be a plate for the lower bag mount or offset cup. The bag center will move outboard 1.25" from the factory crossmember location.

Clear as mud???

Crystal. Do you offer the offset cups as an add-on? How much?

Thanks a lot -Chris

[BigShoe24]

"large hump" How do we know if we have one, is it a noticable difference? Also, were can you find one? Thanks Nathan

[gringoloco]

Tall hump is bolt-in. Low hump is pressed as part of the floor. They came on 4wd and 2wd w/ the TH400 tranny. I got mine off the parts board here.

[watahyahknow]

i asked the guys from flaming river about that once they said they couldnt garantee there setup would work on a one ton dualy maiby 3/4 ton is borderline .
i would actually be a happy camper if there was a rack and pinion steering available for the one ton .
we have a l;ot of corners here in the netherlands and a yearly aproval system for cars and trucks that would force me to chainge balljoints every year because the endplay is too big , the rack and pinion would make it steer better and its designed with tighter tollerances too

[Sweet 85 C10]

Porterbuilt just bring this Topic back to the top for everyone! Happy Holidays!

[slammed1]

Porterbuilt,really nice craftsmanship,welding and fabrication. I was checking out the thread and looking at all the features of the Dropmember and wanted to see if you had a picture of one particular item. I was interested in seeing the rack & pinion c-nothc for the frame up in the front. I know you have addressed it and I seen somewhat of a picture showing it but I wanted to know if you had an inside frame rail shot of therack notch itself. Is there a plate for strengthening up that part of the frame along with the notch or is it just a notch to go in with no boxing of the frame in that area?? Great products,and ingenuity.

[gringoloco]

Look here for notch pics. There is no boxing, but I don't see why it would be necessary. You could box it in for peace of mind, I guess...
