This is what rpm and speeds I have in double overdrice....

so when you go to buy your DRW pickup axle to swap in;

if your going with 215/75/16's (what was used on factory 2wd DRW's)
get yourself a DRW pickup axle with 3.55's for:
1982 RPM @85 MPH in double over.
(if you choose this size tire.you would have the option of keeping your current SRW pickup axle,and running dually wheel spacers out back.some claim even with the full floating axle this puts stress on the wheel bearings.some claim it doesn't because it full floating.i dunno.im hauling heavy using 'em with no problem,but i drive half your speed lol.and actually,if your just doing it for stability,then i would never consider the swap.id go for the spacers without thinking twice.)

OR if you plan on using 235/85/16's.
get yourself a DRW pickup axle with 4.10's for;
2070 RPM @85 MPH in double over.

either way,get's you what you want;around 2k rpm cruising faster than the speed of light lol.

No brainer. With the sterling 10.25 4:10s and 3:55s were your two options. With your double overdrive i would go with 4:10s, otherwise you will be far below your engines powerband

Looks like 3:73 or 4:10's. Any more thought on this?

I would like to go from 4:10 dually to 3:55 single. Keep that in mind Gary.
