Caster, pinion angle, and the vac disco

I have a 2000 DD with a whopping 1" of lift currently that I will eventually make much more trail worthy. I'm stock piling parts as time allows hoping for time in the future to do some actual wrenching.

I realize I will "need" a HP d30 (or 44) before doing any real lifting, but I'm still curious about whether I should get a vac disco axle to allow me to have both good caster adjustment and avoid a spinning driveline (without buying warn or MM hubs).

I've built a '90 with HP vac disco d30 before which allowed my to adjust my caster where I wanted it and put the pinion very close without having to worry about vibrations on the highway. I loved having 2low on the fly with the vac disco and am not afraid of building a cable "posi-lock" or even a pneumatic mechanism to shift the fork.

I guess my question is; does anyone make aftermarket shafts for a d30 that doesn't eliminate the vac disco? I anticipate this heep will not see larger than 33" tires without considerably larger axles that frankly will not be a reality until my current grad student debt to income ratio changes substantially. Having to run OEM shafts will be a deal breaker. No pun intended.

TIA
comments?

No. There are no upgraded vacume disconnect shafts, and with good reason.

Unless you plan on exceeding about 7" of lift, you won't have a problem finding a good median of pinion and caster angles with a hp30.

thanks for the reply.

I was hoping to be able to justify the disco axle for 2lo on the fly.

Get the 2-low for your 231, and beef up your 30 some.
