Dropmember C4
Here's the latest version of the Dropmember... The DropmemberC4. It utilizes C4 Corvette suspension and steering components. The main advantage of the DropmemberC4 is performance, but other plusses include overall appearance and of course, EGO enhancement. It uses either a coil-over or Shockwave (PN SKW1030). It is offered with a ride height of 5" or 6" with a 27" tall tire. When used with the Shockwave, the 5" ride height will put the frame on the ground (with 27" tall tire), and the 6" ride height leaves the framerails an inch from touchdown.

![]() The pros are: Bolt-in; C4 components; rack and pinion; improved suspension geometry and thus performance; suspension system designed specifically for the C-10 chassis; decrease in unsprung weight; fabricated crossmember... not stamped; added crossmember to ground clearance; quality product. Cons: trans tunnel may need to be modified for bell-housing clearance (needs the "large-hump" floor), motor moves up and forward slightly and would necessitate exhaust, drive-shaft, and other hoses/lines/ linkage mods and or changes. That's all I can think of right now... if I come up with more I will definitely share.

Re: DropmemberC4
Nathan,
My Dad's got a 55 Cameo and looking to ditch the straight axle front end. Do you make a bolt-in dropmember for the 55-57 chevy trucks? He's not a big fan of layin frame either, so I guess some type of coil over in place of the shockwaves?

Re: DropmemberC4
I am working on a Dropmember for the 55-59 chassis, and the 47-54 chassis as well. They will bolt-in, and will be offered to use either C-10 suspension components, or Corvette C4 components. I anticipate the 55-59 Dropmember to be available in or near the end of March. A coilover will be an option.

Re: DropmemberC4
Yours is an IFS. Other IFS systems are IFS. In that regard, I don't see any difference. I do like the Corvette base over the typical MII stuff... though there are LOTS of parts available for the latter, something about having Ford running gear just doesn't appeal to me. Was that the "loaded" part?
I'm all set for front suspension but I wouldn't hesitate to go with the PB setup if I were putting together a new truck that utilized a stock or stock-ish frame.

The effort involved in setting it up this way would cost me more than a Shockwave would.

Re: DropmemberC4
Nathan, I may have missed another thread you've posted, but I think what AesC10s might be getting at (because I was wondering myself) is do you offer a dropmember that doesn't require using all the C4 components and does not need the rack? I'd be interested in going that route and still being able to use my stock arms (could go tubular if necessary), and current front bag setup.

What are the concerns with the rack? I have had a lot of people ask if they could use the stock box. I always assumed it was cost... is that correct?

Have you seen the original Dropmember? It sounds a lot like what you're referring to. It can use your stock arms and bag set-up you currently have, but the rack is a must... You can find a MII manual rack for $160 rebuilt... who knows what one on E-bay would go for. As for budget, I know exactly what you mean... that's why I currently drive a 1995 Silverado with 18's and no suspension mods! Turns out that there isn't much left over after the mortgage and expenses for the wife and kids get taken care of! (I've been dumping the majority of revenues back into my business. Tools and equipment aren't cheap in this industry!) Hopefully I will get my own sick ride done in the next year or two!

Re: DropmemberC4
It definitely can be. The deciding factors on where ride height would be are tire diameter and then coil-over selection. With a 26-27" tall tire and the proper coil-over it will set about where you want it. My main purpose in building this piece was performance, I just made it capable of using a Shockwave so it could cover a broader market. Best of both worlds... performance guys get theirs, and the go low guys get theirs.

Re: DropmemberC4
Nathan, you would be correct in your assumption of price, at least from my perspective. Not that I don't think it is worth it because it clearly is IMO. I'm just on a tight budget, and right now it isn't in my budget unfortunately. I am building my truck to be a weekend cruiser and my needs are not really performance oriented anymore, (I'm getting older...) though it must perform better than stock, be as safe or safer than stock, and be able to get low. I think my best option would be to section the existing x-member I have, but it sure would be nice to have the money to buy that piece of art that you have developed.

Re: DropmemberC4
what kind of cost is there for a complete setup? rack, arms, shockwaves, spindles, etc?
Do you see any issues with using larger tires? like in the 29-30" range. |

Re: DropmemberC4

Rebuilt C4 Rack and Pinion- $350 DropmemberC4 Basic Kit- $1500 (Includes Dropmember and C4 Rack and Pinion) Spindles/Brakes/upper and lower control arms (used from salvage yard)- $750-$850 ... I've seen em for less as well. (Keep in mind possible rebuilding of parts/components) Good idea to buy front suspension complete with rack, crossmember, and transverse spring... you can sell off the parts you do not use and recoup a few hundered bucks. Shockwave's- $849 Tie-rod ends- $150 Steering joints and Linkage- $350 Total $3700 + misc. expenses ~ $4000 As for the tire diameter question... 27" will put the frame on the ground, so a 29" diameter will put the frame 1" off the ground. You can go larger than 27" diameter, clearances just get tighter and tighter.
