how many guys on the site have built a 4 link rear for their rig? i want to 4 link the rear of the bronco but i dont really know exactly what im doing as far as meaureing where to put my links and how long to make the links... the longer they are the better flex right... and where do i get the springs... do i go to a spring shop and tell them what i want... and how do i know exactly what i need... i think i need help... am i in over my head...

 

Honestly, some of the questions you are asking leads me to believe that you shouldn't be taking on a project like this, at least on your own. Before you go cutting everything out of the rear of your Bronco, you need to have a plan of what you want to end up with when you're done. A super flexible crawler, high speed desert runner, mud?

You need to have a good understanding of suspension geometry, above average fabrication and welding skills, and the will to keep trying if it doesn't work. A lot of time is involved in the design and build. I've seen guys run a trail rig one time, decide that it doesn't work, and cut everything out and start over.

Longer links will help help flexibilty, but you also need to take into account, suspension link angles, ground clearance, frame clearance with suspension cycling, driveline and drivetrain relationships with suspension cycling, shock and spring placement, wheel contact pressure, etc.

What type of springs do you want to run? A standard coil, coil over? Do you have any idea what the rear of your Bronco weighs or will weigh when it is finished? How are you going to mount them?

I would agree that you are in over your head. I think you would be better suited to stick with leaf springs. With the right springs and shock mounting available, there is a lot of flex that can be had from the stock based suspension.

ok number one i have a great knowlege of suspention and fabrication... soo becareful how you word things.... im going to run standard coils and another guy was nice enough to help me figure out my suspention geometry... but thanks anyway

 

I don't think I worded anything wrong. You asked some pretty basic questions and admitted that you may be in over your head.
Whatever...
Good luck with your project.

basicly all i was stating is that i have never set up a 4 link suspention and i wanted to know how hard it was going to be... i have been building off road trucks since i was 15 and i have a vast amount of knowlege for the age of 19... but i can see that you are unwilling to share information which is the whole purpus of a fourm anyway...soo what are you really doing here... if its just to make smart *** remarks to those of us who arent rock crawlers then thats cool i guess...

 

Seems to me he was just asking you questions on what your plan for the rig is. A rig that's build to play in the mud would be different then a rig plan'd to do trails that requires a great deal of flex. And if your planning on making it a show vehicle is prolly a lot different then one that is just a serious weekend toy. No need to jump on RC's case when from what i read he's asking basic but serious questions. And one that has been building off road road vehicles for roughly 4yrs should see that the ?'s he's asking are true needed info'd questions.

 

Heres some links to a friend of mine who just finished a 4 link and some others... http://rebelrockrunners.org/forum/viewtopic.php?t=1524

Whoa, slow down bud. Don't get your shorts in a bunch. I think there are several in the Bronco forum and in the offroad forum (when I was over there) that would attest to the amount of information I've shared in the past 5 years. That is one of the main reasons I hang around this site, to share what I know and maybe learn a little too.

You were pretty vague on your Bronco's purpose. I asked some questions to get more of an idea of what you were wanting and maybe put some more questions into your head to help you with your build. Not once did I say anything smart assed.

BTW, RCrawler is short for Rock Crawler. I have roughly 5 times the wheeling and truck building experience than your 4-5 years. Basically, I was building and wheeling when you were still in diapers. I've built mild and concours restorations, show trucks, racers, hardcore trail rigs, daily drivers and even a few beaters (my personal favorite). I've had a couple of them featured in different magazines over the years and a few car show award winners. But, I still wouldn't claim to have a VAST knowledge. I learn something new every day.

well im sorry that i offened you but it offened me with the way you told me i was deffinitly in over my head and i should stick to leafs... i do relize there are many diffrent systems out here that will prolly do more then enough for my rig...

now here is what im looking to put into it... i bought this bronco for $450 2 years ago with another motor and trans its got big bronco axles Dana 44 and nine inch full width... im upgrading to a dana 60 front and rear both with disk brakes... and im running 36x12.5x16.5 millitary humvee tires that i got a good deal on... it has no lift and big cut outs... what im planing on doing is buying 5.5 inch lift coils from tomsbroncoparts.com for the front and rear... and basicly miroring the front suspension for the rear with minor mods just to get more flexability.... the bronco will be doing a lil bit of every thing except seeing the street... tomsbroncoparts has 5 inch extened radius arms for a lil under 600 bucks... should i get those and use them or should i make custom radius arms with heavy tubing and him joins?

 

you have a LOT of reading to do! link suspensio0ns are VERY particualr in the way it is all setup from link lengths to joint angles which can determine anti-squt and cause bind and sway.... there is WAYYY too much to just take it all in at once. you need to just do your research first, there are thousands of link-building articles found on the net that can be found pretty easy.

i am with RCrawler though for now you need to stick with leafs and do your homework. i was gonna do a 3-link wishbone on my 72 but after doing all my homework and reading and what not i decided for now leafs would suit me just fine until i feel knowledgable enough to begin.

you need to chill out and learn how to take contructive critism especialyl when you open up, comeout and say you dont know what you're doing... we are only here to help but with an attitude like that help will be hard to find!

there have been many attempts to mirror the front suspension out back and it does not work. just stick with leafs, i gaurantee you they will do everything you want them to! also may i suggest BC bronco coils or cage coils/leafs. i have run both and they are of superb quality. the extended arms are nice but they are way too $$$bling$$$ for me. i just wristed my pass side arm and i believe i get just as much flex as $600 aftermarket long arms!
