what will make my 80 flex more?

[nukegoat]

Not arguing the rest because I don't give a chit, but that's an inaccurate statement, since I never broached link packages from a marketability standpoint.

I pulled the rest out of my ass.....

Indirectly, you did. You said vendors arent selling kits due to the complexity in engineering. the 80 isnt some bizarre machine that nobody understands, though. In fact, the reason we 80 owners are so proud of our rigs is because in many ways they are so conventional - body on frame, solid axles, coil springs, gear driven xfer cases, no traction control, etc.

The reason nobody sells 3 link 'kits' en masse is because the market isnt there.

The best link design I've seen for the 80 that does afford a little more flex while not impacting on road mannerism, is the Superflex arms, and mimicking the design behind holds the greatest promise for the normal, run of the mill 80 guy.

Thanks for the input. I have seens your SF arms and they do look impressive. For me, the long term road has 3 potential options:

- SF arms
- Radius arm flip
- Linked front end

Are there any thing you don't like about the SF arms, or wish was different?

Biggest problem is that the radius arms will hit the tie rod on droop. And you'd be 90% towards a total replacement anyway.

If you're serious about linking the front of your 80, PM me.

You'll have an incoming PM I'm in the process of doing a Y-link steering up front so the tie rod won't be an issue on my truck ever!

I think theres far too many people looking at the suspension set ups the wrong way. They all look at flex first and then the driving characteristics. A 3 link would be a absolute piece of p$ss to build. Especially with the mistakes I see being made. Look at undergrounds set up, great qaulity work... But still see alot of bad decissions. Braking forces. The tower is directly above the diff centre (off centred) it should be centred.. Even "IF" centred, braking forces when in a straight line will be fine, but cornering while braking will see it squirly under brakes. Not to mention the rotation of the pinion under cycle. For this reason a 5 link is far far better. It always distributes the braking forces evenly to each side as it has a tower eachside closer to each rotor(spreading out the forces evenly). And pinion angles under cycle is predictable (If a parrallel 5 link, all arms the same length).

Coil overs not disecting the axle centre. Instead its counter levered behind the axle, adding to the tower forces with leverage. If it was sitting ontop "like its suppossed too" there would be no load or forces at all.

If its for offroad only, sure who cares. But there is a big difference between 3link and 5 link (or as you guys call it 4 link with panhard).

This is like, the first time I feel like you're vaguely validating my set up and complimenting my solution as compared to the 3-links out there. We've come a long way!

Ha ha, I always give credit where credit is due. A 5 link is always going to be far better than a 3 link (handling wise).

Nuke goat, have you had a look at the link seperation on that 3 link? And also the disection line from the lower control arm in relation to axle centre. That axle centre would be rocking and rolling under load...

On the setup that 4WU is putting together? I didn't look closely.

I still have yet to take good photos of the actual links / welding / engineering. I also have only taken a few action shots (posted already - search for the marshmallow thread here). I brought it to Surf 'n Turf last weekend for people to scope out, though.
