GM #15125887 on indefinite backorder

[DirtyBacon04]

I might as well get 89s, especially if i do the winch.

[Philberto]

I have a special mounting idea for my winch that will make heavier front springs unnecessary. PM if you want details.

[DirtyBacon04]

Plus, wouldnt the heavy winch be an advantage now, since the only heavy springs avaliable are 89s?

[Philberto]

As you have 81s right now, 89s might be pushing it a bit. How bad is the rake on your vehicle? Mine's pretty bad, but I have 82s. With the ACDelco springs and my recently-ordered 3" Mark lift in front, I'll be pushing my suspension close to the max I want to.

[DirtyBacon04]

Well then couldnt i get the 89s and cut off a certian amount? I just think the ACDelcos might cause me to rub more than i'd like.
Plus I only have the 2"spacer and about to get the ~160lbs bumper. Dont think my CVs will get to a dangerous angle at full extension.

[DirtyBacon04]

Or would 88s suit my purpose? apprently its not that hard to get them, plus their cheaper!

[djthumper]

Wy don't you take before and after measurements when you get the bumper before changing the springs? Then we can see how much drop it gives you.

88s are also on national backorder.

[DirtyBacon04]

If I had that kind of time, I would. But with the time it takes to order/ship/install, I'll be cutting uber close to my cross country move. I went ahead and ordered 88s. from what I'm reading from other threads, (barton, jon a, gordin, fish) users with similar weight, are vouching for the 88s.

Wait.. when did those go on backorder?

[DirtyBacon04]

gmpartsgiant just let me place an order... should I call to cancel?

[Philberto]

They'll cancel tomorrow. I already tried ordering those.

[DirtyBacon04]

poopie...

Get the 89s. Worst case, you'll top out a lot. Once you understand how much further down you wish to go, cut the springs accordingly.

Agreed.

[DirtyBacon04]

roger that. Thanks guys.
Couldnt I just test it by lifting the front end by the frame to see if I'm getting any CV binding? or should I drive it with the springs for a while to see where they settle?

[navigator]

that should test CV binding but you may not realize if you are topping out the shock unless you hit a bump and it jars you.
Mike Peters had a strut break one time with the 89's but I think we deduced his truck had been in an accident before and everything wasn't 100%. With your extra weight the consensus appears you should be fine as i think there are a few other members running 89's.

I need some clarification on this.

Downward travel of the coil/shock assembly is only limited by the downward travel of the shock itself. The inside the coil lift only controls that, the lift and downward travel, also the higher spring number/rate controls height also but not downward travel.

How can these two act together to change downward travel when only the spacer/shock can do this?

[navigator]

the strut is the limiting factor.
with a standard spring and lift spacer you have to flex to top the strut out.
with a taller spacer and/or a stiffer spring you are closer to topping out all the time.
basically you are driving around already flexed.
Adding more weight from a bumper, winch and skid plates compress that 89 so that you can use it and still have some articulation.

Agreed, but how is the stiffer spring going to change the ability of the cv to turn when full downward travel will not change from one spring to another?

Settling will make no difference correct?

[bgwolfpack]

Weird double post just happened.

Sorry, disregard this.
