Sadistic Iron Werks Single Hinge Suicide Door Kit!!!

In case anyone was wondering the single hinge suicide door kits that were featured in the MT issue awhile back by Sadistic Iron Werks are $250.00 shipped to your door for both sides. One side would be $150. They take up to 2 weeks to receive...They come with all hardware to mount them, and an instructional cd

Here is the link to the MT article:

Here are some photos of the end result!!!

Cool man but the controversy is whether they are a good set or not. Yes i can see they are maid from thicker matterail but will they hold up as long if not longer??

well... that install won't last. It doesn't look reinforced enough. You can make a hinge kit as thick as you want, its NEVER going to make the hinge more effective when you're only welding to 20ga at best... (maybe multi layer 20ga sheet metal). The only way to make that kit work and last for time to come would be to plate the inside of the door jam with 1/8" steel, roughly 6" up and 6" down, etc... Long term, that hing is just going to crack out of the door jam.

However, i don't have any physical evidence with a kit being installed and used for any extend period of time... but if you work with metal, you'll understand the physics of it.

so from those pics your saying it is a bad install, do you know who did it? he has built a "few" nice rides and im sure he did what was required to make it work. also if you look the door is not saging in the pic.

Do you really think that it would get a full article in MT if it was some junk setup? Probably not...

Look at the build pics in the link!!

The Sadistic Iron Werks Heavy-Duty Single-Hinge Kit is built using beefy 3x1/2-inch flat plate, 3x4-inch 1/4-wall box, 2x4-inch 1/4-wall for the door plate, and 1-inch 1/4-wall DOM tubing.

I agree completely with you on the fact that your weld is only as strong as the material you are welding!!

That is something everyone working with metal knows, or should know!!!

But considering the the door jam area of a vehicle is built to withstand high impact as a high rate of speed gives reason to believe that it is structurally sound, though you are cutting into it, the material is in-fact being replaced...

I'm not saying you are right/wrong I am just saying that if you think this hinge system is a complete failure you might as well say that with all hinge setups...whether its one hinge taking the load or two sharing the load btwn each other...

judging by what dev just brought up i would say its most likely a pretty well built kit. ive been doing metal fab for a few years now.

i don't care who built it, i'm judging by pictures. Proof is in the pudding, right?

the rear door jam is NOT designed to support the weight of the door... the front is.

However, this is going to be a reputation fight, and I just don't have it here. Not my truck, so i don't have to worry about when its going to break. Hopefully I'm wrong... who knows.

This isn't a reputation fight. . You stated that its crap and gonna fall apart. . Others said that its built right and won't fall apart. . So u can tell by those 2 pics that it is crap? I don't think so. . . . . . I have seen the build threads from when he put those hinges on and it looked like he braced it pretty well. . . And Devb22 said that the side of the truck is built to take a hit to the side and not fall apart. . If it can take that, then I'm sure it can hold a door. . Especially when its braced. . .

and none of our trucks were designed to lay out on the ground or not have door handles or have five lug suspension, but hey all of that seems to be working out well.

You can see from this picture that he used very thick hinges,box tubing and thicker plate welded to thin mazda sheetmetal



That over time is going to get pressure cracks, leading to door not closing properly possibly. By the time that happens the truck will most likely be rebuilt or in scrapyard.

Is it properly done? somewhat. Those plating inside to original mazda metal isn't much. Doesn't matter if it's 1 inch thick gussets, your still welding to thin sheetmetal. You need to spread the load over a greater distance when you weld to sheetmetal.

What should have been done is 4-5-6 holes drilled on upper side of that square cutout and lower side of that cutout. Then take a 1/8 plate with 3-4 holes drilled over section where the hinge will be located. You then insert into that cutout and plug weld on upper/lower portion and then plug weld the 1/8 plate to the hinge/box tubing. Obviously allowing access to hinge bolt.
