Seeking Infomation on 03

[radar doctor]

Looking to buy a 03. Can anyone tell me what the rear end 11. 50 means? Is that a 355 Rear end or 4. 10???Also This unit has Anti Spin Differential? What is that and how does it work? Thanks Guy's... . and Gal's

11. 50 is the size of the rear end. As for 3. 55 or 4. 10 Dodge now only options you with a 3. 73 or 4. 10, which in my opinion are more viable than previous years especially with bigger tires. Ant-Spin or limited slip they are one in the same, the basically provide a little extra traction to the wheel with better grip in slippery conditions. An option that I could not live without.

Question

Does this mean that a 11. 50 rear end can have either a 373 or a 4. 10 gear ratio??tks.

 

[Prairie Dog]

Yes, and you can get either one in limited slip.

 

[Tony T.]

Yes! 3. 73 or 4. 10 look in the glove box there should be a sticker indicating gear ratio 3. 73 or 4. 10.

More accurately, 11. 5" is the diameter of the ring gear in the rear end. Now only available in 3. 73. & 4. 10 ratios.
