4-Link?

[ShadowRejects]

Has anybody 4-linked their truck on here? I've been considering doing a SAS but instead of doing leaf springs up front, i though about 4 linking it as well as the rear? yay or nay?

Id say go for it... But it would cost you alot more. coil over for the front would have to be huge for them to work good. I 4 linked the back of my truck. Havent got to try it out yet, but it is a nice install for sure. Im assuming a 4 link for a 4x4 would be double or tripple the cost...

I am in the darkness on this one. Please shed light on the term "4-link"

I have heard people mention it, but don't know what it is....

I DO know what SAS is and that is awesome enough, haha

A 4-link is basically ditching the whole leaf spring thing and instead of using leaf springs to align the axle, you use 4 links that attach to it and are attached to the frame. usually 2 are on the outside and 2 on the inside, since it eliminates leaf springs, you have to use coil over shocks instead of leafs.

its much simpler than a leaf spring kit, and alot cheaper, but the coil-overs cost an arm and a leg.

Their not necessarily 2 inside 2 outside... personally never seen that. Look ay it this way, the 4 link does nothing with handling of the truck when it comes to steering. so the axle doesnt care where the 4-link is. Basicly, all it does is keeps your rearend/front axle pointing straight, and stop any twisting of the axle that leafs would have. Also, when you run a 4-link, you also run a Pan head bar, goes from the side of the frame to the middle, or off center of the axle. This will stop the side to side motion of the axle. Let me find you some pictures guys.

Before i go look, in my opinion, now keep in mind i have never been in one yet. My truck is the first i build/gonna drive. But i think stiffness of the ride will determine on the coil over you choose

Heres a rough ideer of where im gonna run the bars

I do have it done and welded up. Im still boxing in the frame though. I will load my pictures to photobucket and show you guy what mine looks like with the frame extended to weld the 4 link to. I dont have my pan head done though.
Heres a link on how to install my setup, if you watch it... you'll understabnd alot more

I honestly don't know much about them since I've never done any research on them, but use this as inspiration
