Renegade Posted August 1, 2007 Share Posted August 1, 2007 I'll be running 32" tires. What gears will the old Renix 4.0/auto be comfortable with? I'd rather go a bit low in case I run 33's in the future. Will a D35 from a YJ bolt in to replace the 35 I have now? Might be able to find one already geared that has been yanked in favor of something stronger. Link to comment Share on other sites More sharing options...

Renegade Posted August 1, 2007 Author Share Posted August 1, 2007 Thanks! According to that, if I find a D35 from a 4-banger YJ with it's OEM 4.10's, it would work just fine(assuming it bolts in). I was leaning toward 4.56's, but that could wait. Link to comment Share on other sites More sharing options...
offroader461 Posted August 2, 2007 Share Posted August 2, 2007 MY buddy runs 4.10 with 33's and he says they are fine... Link to comment Share on other sites More sharing options...
oldjeep Posted August 2, 2007 Share Posted August 2, 2007 4.10's with 33's works just fine. For street use you could easily run 35's with 4.10's. Link to comment Share on other sites More sharing options...
89eliminator Posted August 2, 2007 Share Posted August 2, 2007 i run 33x10.5s with 4.10s and it runs perfect. the engine isn't revving to high and the power is good. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted August 2, 2007 Share Posted August 2, 2007 so you're saying my 33's with 3.07's isn't a good thing? :P Link to comment Share on other sites More sharing options...

JeepcoMJ Posted August 2, 2007 Share Posted August 2, 2007 uh...time to upgrade...in a few months...when I have money. Link to comment Share on other sites More sharing options...
ORCA Posted August 2, 2007 Share Posted August 2, 2007 3.73 - 4.56 for 33's would be tits :cheers: I think anything above or below would be too much or too little. A buddy of mine has 3.73's and 33's, great for wheeling but not the best off the line ;) I've got 4.56's and 35's...it ain't that bad... :chillin: Link to comment Share on other sites More sharing options...
Renegade Posted August 2, 2007 Author Share Posted August 2, 2007 I figured 4.10's would work, just don't want to be lugging the motor & heating up the trans. This truck will only see pavement. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted August 2, 2007 Share Posted August 2, 2007 I'm debating on 3.73 or 4.10 righ tnow as my 89 will be the commute truck from here to whitewater (45 min.) for school and will still regularly see highway travel. 3.73 sounds best to me...

pingpong Posted August 4, 2007 Share Posted August 4, 2007 To me gear selection is partly bassed on driving style, and needs for fuel economy. Also it helps to keep your motor in the peak power range for your tires. I always say go bigger/deeper. I say 4.56's or 4.88's that way when inchitis hits you wil be set for gears Link to comment Share on other sites More sharing options...
Renegade Posted August 5, 2007 Author Share Posted August 5, 2007 I went for a cruise tonite & noticed it is pretty doggy taking off with the 3.55's & "215's". I'm leaning more toward 4.56's now since I will mostly drive short trips & would like the added acceleration. It's not going to be a daily driver. More like a "whenever I feel like it" driver, so I ain't TOO worried about mileage. Link to comment Share on other sites More sharing options...
