If you want to correct your speedo, replace the speedo drive gear with one that has 2 teeth fewer. I believe the part number is 520676xx where the xx are the number of teeth. I forget the number of teeth stock with 3.54 gears (31 rings a bell). It is easy to pull out and check (top rear of transfer case).<br>Marc<br>

I've got a '97 with an automatic, 4.10 gears, and 235-85-16 tires and I run just under 2500 rpm at 75 mph.
