4.88's and speedo acuracy
« on: August 06, 2007, 02:46:08 PM »
I was just wondering how acurate the speedo would be on my 92 YJ. I just put in the 4.88's and I am running 33's. the speedo seems a lot more acurate now than it did before.

Well, if you look at this thread, you'll see you should be pretty close to dead on.  You still might want to verify it with a GPS though.

4.88's will bring the Jeep almost to stock configuration with 33's on, so the speedo should be as close as you'll get.
