Manual Locking Hubs

I have a 2001 SCrew 4x4. It has automatic overdrive tranny.

Has anyone converted a F-150 4x4 to a Warn manual lockout hub setup?

In the old days, you could get much better mileage on the Highway with the manual lockout hubs.

Thanks for any info.

You're right Camille, the front end is a center axle disconnect. The half shafts are connect by vacuum motor when you throw the truck in 4HI. The gear set is a reverse cut 8.8."

I've heard rumors that Curry and a few other companies where in the works of implementing a SAS kit. There would be two types, one would have a rebuilt to your specs axle in it (pretty pricey) the other kit you'd supply the donor axle. Haven't seen anything, just rumors.
