Yes the gears are different sizes (according to the number of teeth it is supposed to have). Did you set it to the correct range, tighten it up and drive it?

i didn't think mine was contacting either, but put it in at the very top & ran it down the road & it's fine.

mikes05unlimited I have an 05 LJ as well with 33's. Your tires probably don't measure out to a true 33, I got a 32 tooth speedo gear and mine is dead on

This one

PPR Industries 30910632 - 32 Tooth Speedometer Gear for 93-06 Jeep® Vehicles - Quadratec

And the one they sent you looks like the correct one for a 31

Neil F. Only a Rubicon requires an electronic device. All other TJ's have a mechanical gear and pickup. 31 is correct but caution on using Quadratc's chart. I don't know if they ever fixed it but they had a wrong chart for a long time.

Danno6102 33" with 3.73 = 31 tooth

Highly recommend regearing to 4.56 or 4.88 if you have the funds. I haven't yet, but I've been running mine with the OD off & it's a ton better at 60mph. Still getting the same mpg. I think from the motor not having to lug to maintain cruise speed.

Quadratec & 4WD have the charts on the items detail page.

what spedometer gear do I need

I am installing 33" tires on my 05 unlimited. Can I just put in a new spedometer gear and if so how many teeth? Or do I have to buy a superlift true speed for 200+. I have 4sp auto with 3.73 on a dana 44 33" bfg km2
