Rear leaf performance....
« on: March 15, 2015, 05:54:35 PM »
I am looking for any suggestions to get the best performance out of my rear leafs when I install my 4WU front link.

I am currently running older 4" Marlin leafs with Bilstein 7100 with remote reservoir shocks mounted vertical. These rear springs have some good use on them already so I am not opposed to replacing them.

Any suggestions....?

I am running 56" Chevy 3/4ton springs w/stock Toyo location shock mounts.
Procomp 5000's for shocks. Don't have any complaints on the way the rear flexes, the pic in my ID is with springs front and rear. Don't think I will have a problem with them after installing the front 3-link kit from Brian.

Either I am drunk or you are, but I know I have not had any alcohol.

Care to elaborate on what you said?

Speaking of the Marlin thread...

I am curious if just the addition of tuned shocks would be enough of a change/ improvement?

I know we all talk about shocks and how important they are but from my experience having tuned shocks some what when I went to work for another off road company, to riding in their vehicles that were tuned from kind of sorta to heavily its some much more than you think it is. Just valving them is suck a big difference. I know I was "shocked" the first few times I wheeled in them. At the time my Toyota had stiffer spring and less tune and I bottomed out more and flexed less then those with softer springs and a heavier vehicle with way more tune.

Was just making sure, I thought that was what you were saying.

If I remember right you had been running Alcan springs previously; now I have to ask, If I had to pick 1, custom tuned shocks or specialty leaf springs (Alcans) which would you suggest?

If Alcans are not in the budget, and it comes to replacing leaves what would you suggest? I will not by Trail-crap, and Marlin no longer sells leafs but from what I remember Marlin and Allpro sold the same leafs, or possible another source?

That's a tough one. Springs hold the truck up and are what is needed to flex for performance but shocks control he vehicle. hummmmm....... I think I'd do springs first with the notion of shocks when I could to avoid refabricating shock mounts.

Hi,

New guy on the block.  I'm considering a 4WU 3 link front for my 86 truck (SAS) but keeping leaf springs out back, so this post caught my attention.  Pardon me for reviving this old thread, but my question is similar to the original poster...is there an as-close-to-optimal-as-possible leaf spring set up...one that best matches/compliments the 3 link?

Feel free to redirect me to other posts/forums.

Cheers,

Roy

Which ever spring is softest. Or closest to spring rate of front. The idea is to have both front and rear act equally with the rear only being slightly stiffer. Other wise you have one half of the truck doing all the flexing and the other half doing nothing.

Thanks.  I get the idea that the front and rear spring rates should be relatively equal.  What I don't know is the spring rate of the 4WU front 3 link...which I suppose is determined by the choice of shock/springs used in the 3 link set-up.

I guess what I'm really asking is this...from other people's experience, what particular rear leaf spring arrangement comes the closest to matching the 4WU front 3 link...Chevy 63s?  Ford F-150s?  Tacoma springs?  Alcans?

Cheers,

R
