Transfer Case Drop

[sarasotausmc]

I should have probably figured this out already, but I haven't.

I understand moving the spacers on the skid plate bolts from over to under the frame. Is that it for dropping the transfer case? There has to be something else involved. I haven't done any of it yet, and would like to get it done right the first time.

Help a brother out?

I didn't do it because I bought a high angle CV rear shaft instead as I didn't like the idea of the increased front shaft angle. Many have done and some have reported frame cracks when using the stock spacers so you'd be better off using a solid piece of ally/steel to help distribute the pressure.

But is that it? Drop the skid plate and rest will follow? I can't see anywhere that my skid plate supports the transfer case.

Not the skidplate, the t-case crossmember is what needs to be lowered. Most trucks have bolts that go from the frame side down then there is the crossmember, spacers, then the nuts. Put the spacers between the frame and the crossmember and bolt it back together. Like was already said, a solid spacer the width of the crossmember would be better.

Transfercase is only bolted to the crossmember, that's it. Drop the crossmember, and you drop the transfer case. Of course, the transmission and engine follow.

Probably be ok, but could lead to the fan hitting the shroud, puts the distributor closer to the firewall, increased front shaft operating angle, etc. Not sure about the shifter, since that's bolted to the floor, may not be enough to affect how it operates.

If I was contemplating this, I'd instead get a CV rear shaft.

Thanks for the info. DYeager, I've been contemplating the CV driveshaft, and I think you convinced me. All the searches I've done have mentioned nothing but dropping the skidplate/crossmember, and swapping the position of the spacers already there.

I did a transfer case drop 1.5" And that sucked to severe of a angle.
Keep busting ujoints. Must use a CV drivrshaft. Fosure.

Be prepaired to spend about 500.00 for a CV shaft if you go 1350 u-joints.

sarasotausmc and lenix, some of the later T-cases can be "clocked" up or down to change the angle of the front D-shaft.
Are you looking to get more breakover and/or different angle on the front shaft?

Never knew this was a burb only forum. Seems to me the title of this forum is "73-91 K5/Suburban/Truck".
