Okay, here's what I know about this so far. I will post updates whenever possible.

)1 Chisholm Suspension used to make drop spindles and control arms for them, but as far as I know they don't any more. You might be able to find some used ones on Ebay or by advertising in the wanted section of this and other websites.

)2 I have been told that using 1-ton control arms on the 1/2- and 3/4-ton trucks will drop them 1-2". The spring seat is apparently a larger diameter or slighter deeper, allowing the spring to sit lower. This was done to keep the 1-tons with the stiffer springs from sitting to high in the front. This method of dropping the front should keep all stock ride characteristics and front suspension alignments, although if you do it I would recommend checking the alignment and camber anyway to be sure.

)3 Front coil springs can be cut down some to lower the front, but too much and ride and suspension travel will suffer. One coil is probably the most I would recommend cutting off. That should be enough for a 1-2" drop. NEVER HEAT THE SPRINGS TO DROP THE TRUCK! This weakens them, and it is very hard to get both sides the same when doing this. I'm sure someone will say they've done it before w/o any problems, but IMHO I think it's a hack job at best and I would not recommend it.

)4 Rear can be dropped using any of the conventional methods: longer shackles, spring-over conversions, re-arched springs etc. Just be sure to check the pinion angle is right when doing any lowering of the rear end, or you could end up on the side of the road with a chewed-up U-joint or worse, a broken driveshaft.

)5 This is pure speculation on my part, but when I worked for a Super Late Model dirt track racecar driver, I noticed that the front suspension on his racecar was almost identical in design to the front suspension of these trucks. The upper spring seat and lower control arm could possibly be modified to accept the racing coil-over shocks like he used. This would give the ability to change spring rates and adjust the height fairly easily. How the race track parts would hold up to everyday driving I don't know, and it would definitely have a big cost factor, but it's something to speculate on.

try Aim industries. I bought dropped control arms for mine, but couldn't use them because my airbag would not fit in the spring pocket.e-mail me if you're interested in them slicknapier@yahoo

If you want to buy mine I have about $400 in them including the new ball joints. I'll take $300 plus shipping trade for slant six stuff. I think they will work on your 74. just do a search engine for aim industries.

On the 1 ton lowers , the one thing to remember is that the bushing hole in the frame needs to be enlarged to the 1 ton dia. 1 ton lowers + 3 inch drop coils for 94-02 = 4 inch drop in the front.
you can use front springs from a 94-02 dodge trucks, just keep in mind that a 3 inch spring drop for the new trucks = 2 inch on the old trucks.
I was talking to a gut a couple of weeks ago who said that early Camaro front coils are the same in Height & Dia, haven't looked in to that Yet.
On the rear i've Fliped the front Hanger a couple of times.
Next one is going to use Fat Man IFS for a street rod.
B 300 4x2 vans use the same lower Contro; arm as the d300 trucks.(72-93)

AIM Industries does in fact show drop control arms for 1970-1993 dodge pickups. I too own a 1977 dodge d100 and am looking to lower the vehicle. I also see that they may have drop leafs for the rear.

iv heard that aim industries isnt that great of a company as far as suspension parts from many outlets i bought uppers for my 95 ram and the bushings where shot in a year i mean lowerin does put stress on certain parts of the suspension but i would shop with caution the part that sucks is they are one of the only places to find many of the parts they offer but when they put a warning on there spindles that non stock backspacing could cause undue stress and catestrofic disaster

I started the following thread.
http://www.mopartruckworld.com/forum/index.php?topic=1698.0

Many people use Dakota drop spindles. You can get them from AIM/ChassisTach, Belltech or Western Chassis. I coulnt find the Westerns listed seperate from a full kit for Dakotas. AIM spindels are on eBay for $180 shipped but many people dont like them. I have a set from Belltech sitting in my house right now. They were $200 from CarShopinc.com + $40 shipping. A lot of places want over $300 for them. The web site is hard to navigate so you may want to call them at (309)7974188. The part # is 2600.

Speed Dragon
05-09-2006, 07:38 AM
So the Dakota spindles do fit the D-series? What year Dakota? And can you use the stock D100 brakes(rotor and caliper)?

ramcharge
05-09-2006, 01:11 PM
It is '91 and earlier Dakotas but only fits '81? and later D series. I think the A arms and steering is different on the early trucks but you may be able to switch it all over if the frame mounts are the same. Some one on another forum had custom spindles made but dont know the cost.

I'll update this post with info and pics when I install them.

btw- I havent seen a Shelby Charger in a long time so I think you have been seeing the other wine/white Ramcharger that is running around town.

It should be noted that the Dakota and Ram spindles interchange but the steering arm does not. This is a problem because the drop spindle and steering arm is cast in one piece. The arm is 3" shorter than stock but I belive it will cause no problems other than a faster steering ratio. I will post back after I try them out.

Were you asking me? I have a Edelbrock 600 carb 3200 stall convertor shift kit and 3.55 gear 9.25 rear with a powertrax unit. The convertor is too much for daily driving so it will be changed. It ran 8.30 in the 1/8 mile before I got it. If I tune it and bump up the timing it will again,but I have set to where I can run reg gas.

Here's a person that used 2" drop dakota spindles and 4" shakles. http://www.cardomain.com/ride/2486461

Replies from bhwood owner of the 87 truck.
These are 87 dakota spindles. You have to ream the tie rod end out on the flip side to except the Ram's tie rod and some mods on the backing plate. The spindle is four inches on center shorter givining a much quicker steering response.

The spindles fit the ball joints but do not fit the tie rods. You purchase a tie rod reamer and ream the flip side of the dakota spindles to except the ram tie rods. The ream I found on ebay $30 It's best done in a mill to control the size. The backing plate needs to be modifyed too! Easy! The shackles are ram shackle made for you year. Bolt up.

I wrote a article on Ramchargercentral.com on the installation of the spindle install page 17. (lowering dodge trucks)

When I lowered my 75D100swb I cut one coil off the front & cut off the bump stop.On the rear I flipped the frt hanger over & cut the shackle's in half I then welded a piece of 1"x2" in the middle making them 8"long. It drives ok a little bouncy in the front dont use s6 springs with a big block or any v8 for that matter! It also wheel hops if I dont have my pinion snubber on.I will be changing it over to a spring under with cal tracs & rancho shocks.

440ww - how did you flip the front hangers? I just got a 80 shortbed - the guy cut the coils like you, and he torched the rear springs at the rear shackle - but it still isnt low enough (still about a 2 inch rake) so I want to drop it more, but the way he torched the springs, I will need to section the bed support rail that sits right above it.
If I reverse the front hanger like you, will that drop me anymore, or will that just realign the pinion angle a bit? I was also considering cutting the rear shackle like you suggest, or getting a set of the drop shackles (same thing) but doing that along with the torched springs has me a lil sketched.

I think I am going to stick with the 15" rims, only because roads around here are not quite smooth. I have my eye on a set of American Racing rims that are almost an exact match to the ones I have now, only no rust. :thatfunny
As to the lowering, I am thinking maybe an inch higher than what you have.

To get your truck that low you would have to seriously modify the engine crossmember. It also is the attaching point for the lower control arms. It can be done but not with bags alone.

well maybe it wont be that low then, but however low i can get it in a parked position with the bag setup and dropped spindles. prefer not to mess with the front geometry as im not that skilled yet.

is there reason why that setup wouldnt work on a 73? it says its for a 74 up, is there a difference in the suspensions between a 73 and 74 on? im shure i could make it work though.

BaggedIndy
05-21-2009, 10:41 AM
No need to scrap the bag idea, just do some more research. The front crossmember hangs about 1 1/2 to 1 3/4" below the frame. The major problems lies in the strut bar hitting the pitman arm I've just about completed my back end and will be moving to the front soon. My plans are to fab a lower a-arm and get rid of the strut bar, and make a crossmember that doesn't hang below the frame. Right now the back end will lay frame on a 31" tire.

12-10-2009, 06:27 PM
Factory 1/2 ton control arms would lift the front of your dually. I got a set of Mid America Custom control arms on my half ton they give it about two to three inches of drop, but I'm almost positive that they are basically very well hand built replicas of a 1 ton lower arm.

Speed Dragon
12-10-2009, 06:51 PM
I think Mid-America's arms lower more than the 1-ton arm does on half-tons. I'd call them and see what they can do for a ton truck. You may have to do a combo of drop arms and cutting a coil or 2 off the springs, or use 3/4-ton springs. Axle flip in the rear is cake, standard spring pad moved underneath the tube. You'll probably have to mod or remove the bump stops though.

12-10-2009, 07:27 PM
What about using a 2in. dropped 1/2 coil,they are the same spring diameter correct.If the 1 ton has a taller spring that should give me more the a 2in drop.

I've owned many a Mopar product, to lower the front end you need not do any more than crank in on the adjustable torsion bars and it's good for at least 2 inches, then just have the front end realigned. Old school stuff.

Must have never owned a D series. Dodge trucks never used torsion bars until the 4X4 Dakota, then 4X4 Durango, and finally the 4X4 Ram started using torsion bars in 2002.

If you have a 4x4 it's easy. Just wait untill the springs have reverse arched themselves. :laugh:

I stand corrected,no this is my first dodge truck. Have owned a number of Cudas, Roadrunners, and challengers and I lowered them all that way.

Does anybody have any experience with the Mid America Customs shocks and front coils?
Shocks: http://www.midamericacustoms.com/72-93ramandramchargerfrontshocks.aspx
Coils: http://www.midamericacustoms.com/72-93ramandramcharger2droploweringsprings.aspx

I am only wanting a 2" front and 4" rear drop on my truck. Would those parts do the trick up front?

As for the rear, their 6" flip kit would be too much. How would I achieve 4"? Does anybody sell a hanger/shackle that would work? What shocks should I use?

Those Mid american are like the ones I used on my truck. I replaced the front springs with new big block springs. I think it turned out pretty nice

That is exactly how I want mine to look! got to figure it out

Mid America customs makes a kit and individual parts for first gen trucks. The kit lowers 6"- rear and 4"-front
