Reverse 4-Link Guys

Edited: 6/18/2007 1:43:56 AM by sic68

ok here is probably one of the easiest arguements you can make. Take a stick,mop broom etc. pull it around that is going to be like a foward facing fourlink. now push it that is reversed.now take something else that would act like a shock while pushing it the shocks are going to make up somewhat for having it reversed. that part is really hard to explain without having you sitting in front of me explaining it. That might even sound dumb but I know what I am trying to say lol. the biggest thing I am trying to say is that shocks on the rear have to be the right ones. I actually did this in a couple physics classes.(I know that kinda contradicts me) see the problem with this is how many of you guys are going to be plowing into holes, and other stuff with your truck? Really you would have to have lots of hp to really notice all the problems or drive like an idiot. I wasn't sayin he should do it I said I have never had a problem with mine. and all the arguements against top bars forward and lower bars backwards might want to look into some of dodges cars and how it sort of resembles a watts link.

^ I don't really know what you're trying to say.

Like Russ said, it's based on the principle of torque. A forward facing 4-link/reversed works correctly for front axles, but not for rear axles. That is because of the principle of torque. The idea of "point the links the same way as the driveshaft" is mainly to keep your driveline angle as straight as possible.

It works backwards based on the principle of torque. It always will, and a whole truck bed full of "it worked for me" will never ever ever change it. Ever.



You hit the nail on the head. There will always be badasses in the world that defy physics. :lol:

Okay, The easiest way that I can explain it...

When the rearend housing tries to twist in the opposite direction of the wheels (the whole "equal and opposite force" theory) a foward facing 4-link is trying to lift up the front end and with enough horsepower and traction you might be able to lift the front wheels off of the ground (think wheelie) Now on a reverse 4-link, with lots of horsepower and traction, the link system will try to push down on the rear of the chassis. Now no matter how much power/traction you have you will never get the front tires to come off of the ground. Initially you would say who cares, but here the clincher. The forces that a foward system uses to aid in traction are the same forces that a reverse system uses to eliminate traction and there isn't a shock in the world that can sure this.

That is only one issue that the reverse 4-links have, there are still severe under-steer possibilities & possible driveline issues actually, anything that a foward 4-link does to help, a reverse system does the opposite.

Now I'm not saying that foward system has zero issues, but a foward system can be designed to work REALLY well. While a reverse system, AT IT'S VERY BEST, will only hold your truck off of the ground.
