rubicon speedometer gear

so when i went to 35's and 4.88 my speedo became off. at first it i didn't have a problem with it but its now beginning to annoy me. i know that rubicons dont use a actual gear. so im wondering what you guys have been using to get your speedo's set back. thanks alot

You just need to install an external electronic speedometer calibrator like a Truespeed. That is what is on my Rubicon and it works fine. The Truespeed isn't cheap but there is another out there that is much less expensive, someone else will have to come up with that brand name for you.

Edit: I just found the less expensive speedometer calibrator in my bookmarks, it's from Dakota Digital ... http://www.dakotadigital.com/index.cfm/page/ptype=product/product_id=126/category_id=287/home_id=59/mode=prod/prd126.htm

I didn't do the original installation but I just rewired it this weekend to better protect the wiring. Looks like you just snip a wire coming out of the VSS on the t-case & splice the calibrator's wiring into the wire just snipped.
