Front axle traction aids are limited because one axle shaft is permanently engaged in 2WD. The ARB Air Locker is the best choice for either axle. The TrueTrac is available for the Dana 44 used in the 1500 trucks, and one person has used it successfully.

Several people tried the LockRight in the front axle and reported numerous problems. I don't recommend any type of automatic locker in a front axle Center Axle Disconnect system.

 

Dana Axle Tag decoding

On my 95 and 97 2500s, the diff tags are about 5" long, made of aluminum and
go between two cover bolts.  The top 8 digit number is the axle assy part
number.  Under that number is the ratio on the left, and then the "bill of
materials" number that is used as an identifier to order parts from Dana, etc.
