i was just reading on RRO and it said that Quarter Elliptical Rear Suspension is not made for street use. i never knew that. i was going to go Quarter Elliptical on the rear of a truck but i can't now of that. do you think i could get by with sway bars with dissconects(spell check)? lata stu http://www.rocky-road.com/quarterelliptic.html

Are you looking to put one on your tracker?
-
no not on my tracker. i was looking into getting my friend a yota P/U or 4 runner and was going to put a solid front axle in with a coiled 4 link and rear Quarter Elliptical.
-
just put in a rear four link also and paint it black ! and some good shocks for the street, maybe an extra pair that can be removed for off road!
-
Why go quarters when coils are the trick
setup??? get a nice 4 link going and coils.
It will be more roadable and better flex than
with half a leaf spring, which is what quarters are.
-
Dont know on what yet, but I want one
-
I'm with wildgoody. 4 link with coils.
-
cuz their is only 1 truck the has Quarter Elliptical rear set up around here and hes not in my 4WD club. i just wana do somthing diffent. i dunno, i might just keep leafs all the way around. lata stu

About the road thing. Most police only know "it can't be this tall" or "you tires stick out too far".
If you feel its safe and it drives ok, go for it. We had a guy in our club (a jeep) that ran one for a year. He know has the whole truck torn down and is making a moster of a truck out of it. I think it will still have the 1/4 elliptical when he's done.

Not exactly.
A proper 1/4 elip is a very, very trick setup, and without some on the issues that appear in a 4-link coil.
As far as "not suitale for road use". This is a common disclaimer. Most 4x4 vendors recommended their lifts for off-highway use only. The 1/4 elip that RRO sells is made by Spidertrax. They don't recommend they QERS (as they call it) for road use. Liability is the reason.
Now, a QERS is technically a 4link using leafs instead of coils. This has benefits. For one, coils are designed to be compressed or stretched, but not both. All of the Sammy coil kits ridigly mount the coils and both ends, don't run bumpstops and both overcompress the coils and use them as limiting straps for droop. Over time, this will toast a coil.
A leaf spring is designed to flex in both directions, to a point. The Spidertrax QERS incorporates adjustable bumpstops as well as limiting straps. This keeps the springs nice-nice and elimitates bind.
I've seen several of these rigs run, and they do awesome. The flex from a QERS and a coily are equal.
The benefits of coils are they are cheaper than custom-designed and built 1/4 leaf packs.
The best route wouldn't be a 4-link with coils or 1/4s, but Coil-Overs. Period.

coil overs make me drool but $$$. i love them. but could i just cut any set of rear springs in half of the Quarter Elliptical? lata stu

STU
Your going to want a donor leaf of the same width. Also I would recommend strongly to run a panhard bar across the back to keep the rear centered.
Check this out. ;D

Alot of good info.
-
wow i thought that you had to use a 4 link or 3 link when doing that. and yes a panhard bar will be in there too. lata stu

and whats the diff between 3/4 Elliptical Rear Suspension and 1/4 Elliptical Rear Suspension?
-
about 1/2 an elliptic ;D
-
i was going to say that but then...

The main difference is how much of the original donor spring you use.
-
thanks 87BlackSami for all the info.

That, and a 1/4 elliptical has the pack attached in front of the axle, with the single attached to the axle, whereas a 3/4 has an entire standard spring-setup, except the rear eyelet of the spring, instead of being attached to a shackle, is attached to the eyelet of another 1/4 pack, that then runs and attaches almost directly above the tire...
Also look into buggy-springs (full elliptical)
Here's some nice little tech-talk from another board I'm on about the differences in elliptical spring setups.

As for the original topic, 1/4 elliptical is EXTREMELY streetable, it is a standard 4-link setup, nothing weight about it, just using leaves instead of coils, and YES, leafs have their advantages over coils.
I would never run a 1/4-elliptical front though, just becuse the geometrics of how it works wouldn't be too great for a front-end.
-
no i wasn't going to go Quarter Elliptical on the front. just didnt think it wouild work well.
