Dropmember in a 69 C10 - Page 13 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I had to go to a pine... the balsa proved to be too fragile. I thought all evidence of that build had been destroyed!

Nathan, great to talk to you today. I will be in touch with you soon about getting mine ordered. One question I forgot to ask you: I'm running a 2-piece drive shaft, even w/ that will one piece still have to be lengthened? And if so, I guess it would be the front half? Also, if the motor is moved, what does that do to core support and fan shroud tolerances?

I think you will be "pioneering" the two-piece drive-shaft and Dropmember combo. I am assuming the front shaft will need to be lengthened, and the carrier may need to be shimmed???... I don't know which trailing arm crossmember you're running.

The core support does not need to be moved (I am unsure why moving the 'radiator placement' was referenced in the Classic Truck's article... The radiator and core support are un-touched and un-altered. The shroud may need to be modified... I know a stock shroud will have interefrence issues with the fan after the install.

67Fleet · 01-16-2007, 01:36 PM

I'm running the stock crossmember but will be going to the ECE drop crossmember for clearance reasons. For 200 bucks it's worth it for me just to buy theirs than spend my time modifying my existing one.

Not sure why the carrier bearing assembly would need to be shimmed. Can you elaborate?

PBFAB.COM · 01-16-2007, 02:21 PM

For pinion angles... The trans will be moving upward, thus changing the pinion angle, if the carrier is left at the same height. There are great references to information about pinion angle that SlammedDime has posted in other threads. It should help you in finalizing your pinion angles.

Im running a Late model Lt1 engine in my truck, would this setup have any effect on the pulley setup? Im not running any AC Just a AC delet.

*Shane* · 02-08-2007, 11:50 PM

No offense, but what is that "thing" over the rear seat area ... reminds me of a Porsche 914.

jlaird · 02-09-2007, 11:50 AM

Is that car on bags? If not, I personally think the wheels look too big. They need to be tucked more. IMO

That engine looks sick!

Lated · 02-09-2007, 06:43 PM

Is it possible to use Coil springs instead of bags with the Dropmember? Does the Dropmember itself lower the ride height of the truck or does the lower ride height come from the drop spindles?

The 'Dropmember' raises all of the control arm pivot points vs the stock crossmember so it does "lower the ride height of the truck". To lower it even more, drop spindles can be used.

Porterbuilt had mentioned the possibility of manufacturing a Dropmember for use w/stock coil springs but I don't thinks it's a 'sure-thing' yet.

PBFAB.COM · 02-10-2007, 01:01 AM

I am still looking into making the Dropmember with a coil spring option... only obstacle is the lower control arm... maybe I will have to start building tubular arms as well....

If I were to use the stock control arms would I be able to use coils?

Currently steel coil springs are not able to be used with the Dropmember. The mounting location for the steel spring in the Lower Control Arm would put it too far inboard. I will be building control arms in the not so distant future, and will design them to be used with either a bag, coil-over, or steel coil spring.
Your stock suspension components will work fine with the Dropmember (control arms, spindles and brakes). You will however, need to trim a little off the back of the lower control arm for clearance at the billet mounting block on the Dropmember. Feel free to ask any and all questions.

watahyahknow · 02-10-2007, 03:56 AM

would be nice .... you could make them custom size too

Lated · 02-10-2007, 05:42 PM

Would the Dropmember still allow me to use the stock drum brakes?

I'd have to scrape the money together just to buy the DM, so cash wise doing a drum to disk conversion is pretty much out of the question right now which is why I asked about the coil springs earlier. On the same note, I know the steering shaft would have to be replace but can the original steering column be saved? One more question and I think I'm done, at least for now.

My truck came with a three on the tree so it has the small tranny hump. Anyone know where I can find one of the bolt in tall humps, or do I have to fab one myself? A lot of questions I know, but I'm still somewhat new to all this the most involved project I've done so far is replacing the window regulators.

They should be fairly easy to hunt down, either on the parts board or at a wrecking yard. I'd expect to pay $15-30 for one. If it comes out of a TH400 truck, it'll save you from having to deal with the holes that'll be in the middle of it if it's a 4-speed truck.

watahyahknow · 02-10-2007, 05:48 PM

you can mount stock spindles so i guess the drumbrakes will fit too

hammered65 · 02-11-2007, 04:35 PM

Nathan, have you or any of your customers installed the dropmember with a big block in a 64-66? I am curious to see if this will work.

PBFAB.COM · 02-12-2007, 12:26 AM

Hammered 65-
The Dropmember will work with a Big Block... the fit is a little tighter, but is do-able. I should have the motor mounts for the Big Block done by the end of the week. I am not aware of any BBC/Dromember combos in a 64-66... yet. There have been several in the 67-72s.

The Dropmember Back-half will be making its debue soon. Expect some pics in the next week or so.

64shortc10 · 02-12-2007, 12:52 AM

Nathan,

I wanted to order my power rack and all the stuff need to hook my steering shaft up to the rack tommorrow. Do you now how much?

Sweet. Thanks for the reply back Nathan. Look forward to seeing the rear setup you have in the works. Would you happen to have any pics of the big block combo in the 67-72 trucks?

I am currently mocking up the big block so I can get the motor mounts done. I will throw a cab on the chassis Friday and snap some pics. The big block does have to move up a bit more than the small block (about 1/2 to 1"), to clear the rack and oil pan. I will be seeing if the trans tunnel will need to be modified... it will be close!

jasonpickett · 02-12-2007, 01:28 AM

I was wondering if the performance online upper and lower control arms will work on the dropmember.

Jason-
It doesn't look like those arms would work. The reason that a steel coil spring will not work is because the Dropmember narrows the track width. It would be necessary to move the spring mount outboard. I will be building tubular control arms in the future, and intend to provide the Dropmember with a steel coil spring option.

How will the price of your arms compare to the Strong Arms? Would the "package" price of the dropmember be comparable with yours vs. the Strong Arms? If it's close (or better yet, the same or better), I might just hold off an get the complete package then.

Hey Nathan, just bundle up the Dropmember, Arms, and back half, I'll send you a frame to attach them to so it's easier to ship, ok?
