anybody can tell me if I can swap a 99 1500 rear end with an 03 1500 rear end, do they match up?

 

Pretty sure the 99 rear end is smaller then the 03 so I would say no

 

Would have to check leaf spring spacing, track width and since the 2nd gen has rear drums and the 3rd gen discs, your braking bias would be all kinds off, requiring an adjustable proportioning valve.

 

The 03 rear end..... the 9.25.... is a problem rear end..posi clips fall off..sure you want to swap..

 

The 9.25 is still being used today. The only differences are in the spring perches on the axle housing. The 2nd gen Rams had a narrower spring spacing than the 3rd gen. The rear brakes are also different as the 2nd gen uses drum brakes and the 3rd gen is disc brake.

 

Pretty much the same differential. Basic design has been around since '72 (my '74 Monaco had one).

 

yes, it is but 03 thru 05 have the clip problem the other years do not..

 

I never had that problem through 100,000 (before I swapped it for the D60).
