I was just wonderin about some quick qustions about a custom 4 link air suspension set up. is the parallel set up better than the triangulated set up? wouldnt the axle turn or rotate with aired out or what keeps this from happening? or is it all about what set up you use that will make the least rotation? would a air suspension be a good idea for a daily driver or is it more along the lines for some of yalls trailer queens? you dont see many people driving around with a air suspension.
if you go with a triangulated 4link you wont need a panhard bar. parallel you will need to add a panhard bar. the axle is gonna rotate no matter what you do. thats why you set the driveline angle at ride height. if the airbag suspension is set up correctly and no parts are rubbing the bag, you use quality fittings and hoses, you can get years of trouble free service out of an airsuspension set up.
Yea, all those semis hauling the **** we need to live on are levitating on pixie dust, not air in those AIR BAGS. Do a search and learn from this board. Tons of folks here that make thier living in custom cars and know air systems.
what about the length of the bars? i have a guy that builds his own 4 links and said to give him the length i want 'em to be so about how long should they be to give the best result? i mean i magine if they are too long they would flex and bow and probably wouldnt last too long.
It's all a matter of how much BEEF you want to throw at it. I've built full tube ch***is rockcrawlers running 42" tires and dana 60's with 4' long lowers made from 1.75 DOM Typical "street rod / mini truck " triangulated 4 link will utilize 1" DOM lowers about 24" long.
Curious, triangulated 4 links don't sway from side to side? Hmmm looks to me if they do, but not any more than the rubber bushings will allow, am I correct? Just looks like a lot of stress on the bushings to me.
Just curious what are you putting this under??? if it is your 52 chevy. Ch***is engineering makes a leaf spring kit that bolts right in. Using the weld on pads for the housing. But going the other way The triangulated is the way I would go if you want to use a 4 link set up. They make a universal kit stated for a 32 ford but you can put it under anything comes with all the brackets, bolts, and weld on hardware. Weve got two installed and there doing fine, with carrera coil overs. No bushing problem. Comes in stainless or steel $200.00 to $300.00 w/o shocks
GM used the triangulated four link from the early 60s to when they quit building rear wheel drive sedans in the 90s. Fox body Fords came with triangulated four links... While it is a packaging compromise (ie: it allows over axel exhaust and a back seat) it works pretty damn good.
yea a airbag set up is a thought on my mind. They look clean dropped to the ground but i was wanten somethin realiable and i was thinkin about the coilovers too. i know suicidedoors.com has quite a few 4 link set ups with super pivot ends instead of the polyurethane bushings, between $250-$400. Just tryin to do some homework on some stuff before i end up wasten my time and money
I realize that GM and Furd used the triangulated 4 link, someone tell me there isn't any sway from left to right when cornering hard. Has someone ever checked the sway of this suspension with one of a panhard or Watts setup. My thinking is that all of them have some sway, with the watts setup the least.
Best price I have found is here http://www.trail-gear.com/links.html If making your own links I would order L/R joints and buy a left hand tap so you can make adjustments without removing the arms
