Coil Options

Post by Wes »

Starting to do up a 1-link setup for the rear of my beast.
Just wondering if anyone had any opinions etc on the best set of coils to use for this?

Ive got the EB 3.5"ers up front with a D44 HP, and a D60 out back. Need some coils for the rear that will even it out a little better but still flex

thanks doods

I think you are doing somethat none of us have really done, it would all depend on how and where you are mounting them and how much lift you need.
8-9" susp, 3" body lift, 39.5x16 TRXUS STS, 342 stroker, C6, NP205, D44HD mini spool-coil sprung, D60 limited slip, 4.88s

Yep realize that part, just wondering on what coils are too soft/rigid etc.
So far ive been told Aerostars, XJ's, or even the JD EB's

Yeah, I think you are definately on your own. EBSTEVE used EB coils on the rear of his EB. He seems pretty happy.

I think a slightly stiff rear suspension is good for overall stability, so I think I would shy away from super soft coils.

I don't like the idea of coils under the frame rails, and I don't think there is enough room to outboard them.

You're in for some trial and error for sure. Keep us posted.

I am not quiet the same in my EB but I started off with a set of stock EB coils from a 67, then a set of KbarS 3.5" springs and they have both been about the same performance wise.
I have adjustable mounts for the stock springs and with the lift springs I took them out and had a god ride height.
I agree with Nobody about being a bit stiff in the back so I think I am going to try a set from a full size 4x4 70's Ford truck in the hopes of them being a bit stiffer.
Not that it matters but I have a set of Wildhorses coils that I was thinking of stuffing on the back but they were soft in the front and I think I am going to skip them because I don't think they will help with stability.

Also I would get the coils out as far as you can to keep it from acting like a teeter totter and I had problems with the Bronco going up hill when the weight would shift to the back corner so I changed the shocks from the picture to an outboard setup and it helped allot.
The picture is old and allot has changed but you get the idea.

well I got some Moog replacment coils from a '78 Bronco, they were free so thought i might aswell try them. anyone have any opinions as to if they will be long enough to get some decent flex?

a one link will flex no matter what you put in it are you going to solid mount both ends or leave one end free like a jeep?

They are plenty long but they may be a bit stiff but you will be able to swap out EB coils to get different rates.
