I'm going to need a 35 tooth speedometer gear for my upcoming gear swap to 4:10, as I have a feeling the shop doing the install will not change that. What is the brand most people use? And am I correct in choosing a 35 tooth for 33" tires, 4:10 gears and a 4.0L/32rh combo?
 
If I was picking a gear I'd get the cheapest I could find. I'd also just do the math. Get everything setup and running then just figure out your GPS speed vs your speedo. Check what gear you have and run the numbers to pick the correct gear. No guesswork that way.
 
I'd say most are running a Mopar gear and have a phone with a GPS speedo near by. Years ago a budy of mine used his girlfriend's nail polish to paint new numbers on the glass of his CJ-5's speedometer. It was in his budget and worked.
