Quarter Elliptical 4-Link Rear Set-up

Wanting to get some input on this 4-link rear quarter elliptical set up in terms of its performance and its ability to perform both on and off road...anybody? How does it compare with a traditional 4-link rear coil over/ori strut set up?

 

WTF with those inverted leafs? My opinion, if you have the skills, time, and $$$ to do a link setup, and don't switch to coilovers, you are missing the biggest benefit. This setup is more tailored towards slow speed rock-crawling/flex.

 

What are the disadvantages of a quarter elliptical rear set up in terms of streetability?

 

I’m being back those thread. I was wanting to do some kinda 4link on the rear of my international build utilizing a tacoma chassis. But my biggest qualm was not having the tow capacity. These 1/4 eliptical set ups are madness. But they perform so damn well. Articulate like a bastard. But the progressive load with weight. So u can tow with them. Really it’s GENIOUS.

any key else ever done this. Where did these pictures come from. I would love to pick this dudes brain!!!

 

That’s really a four-bar setup, a four-link is adjustable at the frame and axle for anti-squat. If the builder did not understand how to set up the geometry and just welded in mounts where ever they fit, then it likely works like crapola. The geometry isn’t that complex, but it will make a huge difference in use. The thing flexes on a ramp, in a static position, in a parking lot, but what really matters is how it performs on the trail, how the springs allow the suspension to compress and unload during dynamic demands. This can make the difference between getting over and rolling over. Aside from that, there are driveline angle issues, brake line lengths, and so on, to consider. Coilovers, limit straps, and some engineering assurances would be preferable.
As far as streetability, you could use a four-link on the street, but there heim joint rod ends will transmit lots of vibration and shock into the vehicle. Using bushed ends like the four-bar systems you see on modern Jeep axle setups would work fine, but it’s a lot of work unless you are building something special and not a DD.
Is the juice worth the squeeze?
