Capacity of dropped spindles

I have a 68 GMC Burb, that has a 73 Malibu SS-454, 4-Speed Wagon Motor, I was about to trade it for an LS but when I found out via Research itís a keeper, (one of 60), Has been gone through and is now a 468, My question is since itís heavier what spindles would be strongest? Was told not to go 2-1/2 or 3Ē, due to weight, itís about to go through full redo, as soon as we move to new place. Iíve seen many BBC A and F Bodyís with dropped spindles, but they arenít trucks.. I thank you all for any answers or input,


It will sit on 20s, 2600 bags and HD A arms, maybe go with Lay arms,it will be just close to layiní out,

Roy
PS itís already sittin on a Pro Hopper 2 pump 4 dump system and I have got everything to convert to bags, I carry My Hayabusa in the back so I can only bring the floor in rear up 2Ē.

I had to look up Hayabusa..... I had never heard that name before.

I don't know about the 3" but there are a lot of big block trucks running around with 2 1/2 dropped spindles.

If you don't get any replies I will try moving this to the suspension forum.

I'm not sure who told you this, but in my opinion this is not correct.
Any 2", 2.5" or 3" drop spindle will be fine.
I prefer ECE (Early Classic Enterprises), Belltech, McGaughy's or Western Chassis.
Is your truck still drum brake or has someone converted it already?
Buy 63-70 conversion spindles for the easiest install.
If its been converted to disc already,... you will need to know what year stock spindles are on your truck now.

Re: Capacity of dropped spindles

Itís drum but I will move to Disc CPP kit, The question is because the stress point on the 3Ē is lateral if itís cambered but I believe itís gonna be fine, I know certain brands are thicker. I will probably go with 2-1/2Ē but I wanted to keep it as close to NOT bottoming out , but being able to get it down, Lock Doc here is a pic of one of my bikes I do Custom airbrushing so Iím gonna do truck like bike.
