Rubicon question
I've got a neighbor who has a Rubi. 2005 I think. He's getting ready to lift
it and put 35" tires on without a gear change. (not a choice I'd make but non-the less). He's wondering what he can do to recalibrate the Speedo without going to the stealership. I'd know what to do if he had a CJ. My guess is he needs a computer reprogramming. True? Thanks Rich |
Re: Rubicon question
He is going to have to buy a speedo gear from the dealership, according to
the ring and pinion gear he already has. I used this link to figure mine out: http://www.raingler.com/tech/speedoChart.asp Funny thing is that the parts guy at my dealership said I'd have to reflash my computer but I bought the proper speedo gear anyway (he said it wouldn't work). It does. I really think its a bad idea not to change the gears with that size tire, might be doable with 3.73 but my jeep had 3.07 with a manual transmission when I went to 33's and it was so bad I didn't drive it until I could buy the gears.

Re: Rubicon question
Oh I totally agree with you about gear changing. My CJ7 has 33's and I'm
running 4:10 gears. They are about as high as I'd go with 33's. 4:56 would be a better choice at a minimum for him. Some people have to find out for themselves. He will. It s funny he's a nice guy, he comes to me for advice all the time, but never takes it. Then finds out later I was right.... Go figure. You can lead a horse to water, but making him drink is his own decision, eventually he'll get thirsty though.

Re: Rubicon question
Replacing the speedo gear would hold true for any Wrangler except the
Rubicon. The Rubicon IIRC uses a tone ring and induction pickup in the t-case for the speedo signal...remember, it uses a different Tcase than the standard Wrangler. Hence, the computer probably *will* have to be recalibrated. Or you can get a Superlift TruSpeed speedo recalibration unit, but I think a trip to the dealer will probably be less expensive.
