Atlas will add a couple leafs (or make all new) and get me the lift in the rear, maybe adding a block? Do I want to use a shackle for offset or just have them make me a set of leafs and bolt directly? Pros/cons?
I would get the proper leafs whether it be adding 2 or 3 more until you get the correct height based on your fully loaded weight. Try not to get 1 single HD overload as you will lose flex when off-road. It will also ride rougher. Skip the axle blocks completely unless you are going to use it as a traction bar at the same time. If the block is done wrong, the thin axle tubes and axle mount ears will rip out and the axle will rotate, destroying at the minimum your rear u-joint. Skip the shackle as you may/may not get vibrations. Properly built leafs will take care of the lift. You can also get them made to center the rear axle better. If you just lift a normal M/L van 4", the axle will sit about 1/2" - 3/4" forward of the wheel well center. New leafs can be made with the center bolt back 1/2" to correct this.

I’m not a fan of subframe spacers but after looking at this install of the 2” OV kit, I’m not opposed to doing that.

My spacer bushings are hard and cracked they were on the list for destruction anyhow. But I’m not sure I can even do larger spacers because of the attachment of the Tiger coach. I’m digging thru SnoDrtRider’s thread for the home-brew approach, great info!
The 2" blocks are a perfect way to get room for the 29 - 30" tires you have as well as making normal engine maintenance much easier! You can actually get to the throttle body as well as plugs, wires, cap and rotor easier too. Since the body mount bushings are hard and cracked, I would look at replacing them with new ones while doing the job. Get a 90 - 95 2WD Astro/Safari intermediate steering shaft off E-bay or from a junk yard.
Please skip the keys unless you really NEED the extra lift. You will be replacing idler arms after every off-road expedition if you go too steep on the angles.suntinez wrote: Have a call in to Gerald for the torsion keys – does ANYBODY else make a re-indexed key for the long arm Astros?
I just got KYB's and don't think they are any better than Rancho's. From what has been said on here, the Bilsteins are the way to go. I personally like Rancho's.suntinez wrote: FRONT SHOCKS:
I know that Rancho 5000 is what OV sells with their kit. Not a fan of the Ranchos. Any other good options? Clearance in the front seems pretty tight, based on the install of the Bilsteins not sure what I can squeeze in there.
Definitely 4.11's minimum. There won't be much difference going from your current 3.73's. Since you are pushing 3 tons almost, I might consider 4.56's as long as you are not hammering on it when off road. The pinions will become the weak point due to the small diameter head and smaller contact patch on the gears. You can easily modify the DRAC (search it here) to compensate for tire and gear changes.suntinez wrote: GEARING:
For a 4” lift (if I can get that), what is suggested for re-gearing front/rear. My drivetrain is definitely struggling already, don’t want to add to the problem.
