Just put 31" tires on my '97 Wrangler Sport and have totally lost 5th gear
and lots of pep and power. I have read on this forum the MANY MANY
complaints about this and figured it was coming. According to the mechanic
at the four-wheeling shop I have 3.53 (?) gears now and he suggest I go to
4.10 or 4.11s. My question is, before I shell out $1500, will this really
get my power and pep back in my Sport? If it will, I'll drop it off for him
on Monday, but wanted to check with the experts out there, before dropping
that much cash on a "maybe" solution. Thanks for any feedback. Also, does
anyone have a pointer to a site that will get me some good information on
other performance improvements I can make on my TJ (headers, cat-back
system, chip, etc.).

Thanks Again....Chris
Red '97 Wrangler Sport

I don't believe TJ Sport's came with 3.55's, in '97, either 3.07 or 3.73's,
most likely 3.07. If he is going to charge you $1500 for a gear swap, find
another shop, it should be closer to half that. 4.11 may be OK, but when I had
3.73 and 31" tires it was fine.
