Bending suspension link.

Im basically wondering if a JD2 model 3/Got trikes style bender could do these bends. I read someone that they couldn't do an S bends but I am wondering if there is enough spacing to do something like the arms below.

Putting together information to build my own long arm kit and this seems to be a snag. I am also in the process of getting ready to build a tubing bender....

Run a radius arm setup instead. I think if you had a small enough die you could achieve those bends.

Here is a Ruffstuff kit i installed on a buddy's 98' 2500. Used Thuren 3" coils and fabbed up a better trac bar.

Do straight links and modify the body mount.

I like the radius arm kit, but I really want to keep 4 links. When you say a small die how small do you mean? 6 CLR vs the 7.5 clr

I believe even with hacking off the body mount I would still need 5 of lift.

Not sure on the die. It looks like a pretty tight bend. What size tire are you wanting to run with that much lift? The ones in the pic i posted are 39s.

With them goofy bent links you don't need any lift?

Right now I have 35s, and wife made it very clear I dont get new ones till they are bald. I wouldnt mind 37s.

With the goofy bends I think I can run 3 easily, maybe 2.
Had a few tell me with the bent arms you can do 40 with 3 of lift.

The links are bent because of the body mount correct? If you make the body mount flush with the floor and run straight links then why would you need more lift?

I see what you mean.... though Im not sure how I would change the body mount but still have it strong enough to hold the cab up with the space allowed....

No offense, but in this case you probably shouldn't be fabbing up...anything structural.

Its not so much that I dont know how... as in there isnt space in that area to do so in a way that would make me happy.

So you'd rather have some goofy bent links that will be prone to buckling, than doing a little sheet-metal work for a ...cab mount? Gotcha. Carry on.

Not trying to start a bickering max but...

1. This truck won’t see hard core wheeling at king of the hammers.

2. I’m obviously trying to mirror a design that has already been used with good results...

3. I am still inexperienced with fab like this... I am good at building things from plans, but design has always been a hard point. That being said if I never try to expand my skill set I will never get better... at this point I’m trying to see if building a bender is going to be worthwhile so I can bend the arms... or if I just need to buy those 5” lift springs and be done with it.

( puts on flame suit)

You are trying to mirror a design that was intended to be installed by any moron with a socket set, with a lot of inherent compromises.

That is the nice thing about building your own stuff, you don't have to compromise on certain things, like weak upper links to clear a cab mount.

Well, good luck, gotta start somewhere I guess.

If you have the skill set to build a bender and then use it to build a custom link suspension then you can build some new cab mounts. I mean how many cab mounts does a guy need anyways?


When all else fails...build up.

I'd be looking to put that link on the inside of the frame, and notch-n-rebox a bit of the inside of the frame where it bends in/up if needed to clear, to run a straight link. It looks like there's room to do that on my '01, anyway. Upper links don't need to be monstrous if you can keep them straight. Having done it both ways, I'll do a lot to keep straight links.
Or refab the cab mount to do a jump-over sort of a thing.

As for the bends themselves, I don't know about a GotTrikes bender, the JD M3 can do S bends down to about 3" of straight between them without too much headache. If you get creative with (making your own) support strap, you could probably get closer, maybe down to 1" of straight (if they're offset 180 from each other; if they're offset other than 180, you'll need probably a minimum 4" of straight tube between bends), but you're not going to pull that off with an as-delivered JD M3 die set (mostly the support strap). If they're on-plane (not what's being asked about here) you can bump bend as close together as you want with a JD, probably with most benders.

Decided to google body mounts to just see what ideas are out there.. no wonder yall think Im being ridiculas.

Watched this video. Ill have to climb under my truck and play with a few measurements but Im thinking I can build a body mount like what is in the video (using 1/4 instead of 1/8). I can probably remove the existing body mount as it is only secured with a few short welds and move the existing upper mount inward towards the frame and that might give me the clearance I need to do a straight upper link. Ill have to look to see if there is any reinforcing above the upper cab mount on the body but Im sure I can overcome that with using some plate to spread out the load.

Another option might be to sandwich the mount between the frame rail and cab, though Ill have figure out how much room I have.

Thoughts?

What is the purpose of the truck? I know you said you weren't going to do hardcore wheeling but is it going to be offroad at all?

I mostly do the beach around here. There is not a lot of wheeling around here in Houston though there are other places I wouldnt mind doing a few easier trails. Big reason for not wanting to do a huge lift is it spends 95% of the time on the road.

This project is more for developing my skills and give me something to do during my semester break. Also the long arms have a big reputation for giving a better ride. Ill also be doing a shackle flip in the rear.

Couple things you can do to reduce the crazy bends. You don't need that long of links like the dodge offroad kit. Check out the synergymfg kit.

https://www.synergymfg.com/Synergy-D...t-p-30960.html

They run a slightly shorter links and have an UCA with one bend. I have this kit on my dodge and had to slightly trim the body mount to clear at full bump. Single bend is plenty strong in this application and running 3" springs and 37's. Been prerunning my truck in baja, JV, Barstow, Pismo. All over the place with 0 issues.

Here is a Ruffstuff kit i installed on a buddy's 98' 2500. Used Thuren 3" coils and fabbed up a better trac bar.
What type of joint does this use at the bracket on the frame side?

1.25" heim at the frame. bushings at the axle. 7/8" joint at the radius arm to lower link.
