Del-a-lum bushings are they worth it over poly?

I have a 69 in which I am doing frame off resto. I am going to have the a-arms powder coated so I will need new bushings. Are the Global West bushings and shafts worth the extra $ over just replacing with poly bushings?

Re: Del-a-lum bushings are they worth it over poly?

Hi i used poly bushes on my upper A arms and to be honest they were rubbish , they were energy suspension ones , there far to soft deform to easy and are not up to the job. I turned some new bushes up at work out of harder nylon bar and they dont deform and my suspension doesnt rattle every time i go over a bump .If you have the money buy the better bushes .
Pete.

If you want a better performing geometry
As stated above, most of the 'kit' type poly suspension stuff is junk.
The durometer of the material is all wrong for most vehicles and the deformation of the bushings allows the suspension to rotate around the bushing vs. maintaining the geometry needed for excellent handling.

Might as well use 'Jello' as most of the kit bushings

Re: Del-a-lum bushings are they worth it over poly?

I had polys in there. I had done a suspension upgrade a couple of yrs ago. They were better than the originals. But now I am doing a body off resto. So I am going to powder coat my a-arms and subframe. so wanted to hear from those that had maybe used both. John or Peter, have either of you used the rear leaf spring bushings?

Re: Del-a-lum bushings are they worth it over poly?

I have delrin bushings in my uppers and lowers. I wouldnt go any other way. As far as leaf springs, you can use delrin in both sides, but if you use it in front eye of leaf spring it will be a harsher ride than poly or rubber. Just keep that in mind.

Bushings will NOT improve the horrid geometry these cars have. These bushings will act like a bearing and allow the suspension to move freely and without binding/deflection. I've put them on every car I've ever owned and I love the feel and performance of them.
That said, you still need to fix the geometry by adding a tall spindle, or tall ball joint or relocating the upper control arm. Nothing else will fix it (even tubular control arms) and you will feel a huge difference by doing so.

you are of course correct for 'changing' the suspension geometry

The wording of my answer doesn't convey the thought I was trying to get across
By "better performing geometry" ... I meant - a constant and not continually changing geometry during travel - as effected by the movement of the bushing through the load cycle of the suspension during a cornering and/or braking event.
The 'poly' system will have excess movement, when compared to a solid bushed set-up, and will allow lots of geometry change.
I guess I should have said to think of it as a constant geometry vs. a better geometry.

Do as suggested, in using the taller spindles or other common mods like the Gulstrand, to get an improved overall geometry for the vehicle

Sorry for miswording the answer ...

I fitted poly bushes all round and the rear spring bushes are firmer than the old rubber ones i took out , i also removed the rubber from between the spring and the axle as well to tighten the back end up . I do get some road noise coming through but i can live with it . Upper a arm poly bushes are a waste of money , being thin there not hard enough they need to be solid, its not so bad with the spring bushes as they are bigger .

Re: Del-a-lum bushings are they worth it over poly?

I am going to go with the del-a-lum upper and lower bushings. Tyler do I also go with their offset shaft or the standard? And for balljoints do you have a part# (MOOG)?

Rock Auto may have your best price on ball joints. Moogs are $21 upper and $25 lower. AC Delcos are a couple bucks more.

Are they the tall ball joints? Part numbers?

No, standard height. Moog does not make one that bolts right in. Talls you have to get from Howe or somewhere like that and I think they run around $80 or so. The G mod is free and the results are similar. I don't have either one but am pleased with how my car handles after doing a complete poly rebuild along with new coils/leafs/shocks/sway and 17" tires.

Re: Del-a-lum bushings are they worth it over poly?

so what is the exact advantage of a taller spindle? common mods like the Gulstrand? What is GIlstrand? I myself was going to order all the suspension i can from Global West. They claim the power steering box they sell (600) is exact box that Detriot Speed tries to sell as their own. Guy at Global says he talks to GM, as its a GM box, and said everyone gets the same box to sell.

You won't regret it. If you are using stock arms then the offset cross shaft will allow you to dial in some extra camber without affecting the caster.
