So im looking for a steering stabilizer for my 99 2500.. i start reading on some and see that there is 2 size of front diff tubes, 3 1/8 and 3 3/4. Im reading this and they say its rare to have the smaller tube on a 2500/3500 unless its a light duty truck, under 8800 gvrw...so i go measure mine and sure enough its the small one, they say this is on a 1500?? So I look at the door and it says 8800 gvrw....so i guess what i'm wondering is did someone switch front diffs on this truck at some time?? I got it in 04?? and if it is a 1500 should i be worried about anything?? thanks for any info...

 

8 lug or 5 or 6 lug?

8 lug is a 2500.
