Rough Country Entry Level 2" Spacer Kit - Issues with Auto. Trans. And 33" Tires?

Looking at putting this spacer kit in a 1998 Sahara that has an automatic transmission. Should I be aware of any issues? I would like to use 33" tires, but will go with 31" if that creates issues. Anything I should be aware of?

Thanks

Rough country doesn't have the best reputation for quality. But spacers alone couldn't be that bad however most BB kits are similar in price for parts included. You could run 33 inch tires as long as you get extended bumpstops. There's not gonna be much room for flex so you will need the longer bumpstops to prevent the tire from rubbing the fender. JP magazine did a story on running 33s on a 2 inch budget boost check it out on their website.

Pekoe,

Running 33's on a TJ with a 2" lift can be done, but you'll need to take a few thing into consideration. First off being the proper bump stop length. This will prevent you from rubbing the fenders when flexing the Jeep. With the 2" lift, you won't get much room for the tires to flex, but it can be done. You may want to look into adding a 1" BL to clear the tires.

The next thing is the wheel backspacing. If you're going to be running a 12.5" wide tire, you'll want to get a wheel with a back spacing of at least 3.75". Even then, you may need to adjust your steering stops to prevent rubbing at full steering lock.

Finally, the Jeep will loose some performance when adding the weight of the larger tires. You may want to look into re-gearing your axles to get the performance back to stock. Other than those things, you should ahve no problem running the 33" tires.

Please let me know if you have any questions. I'll be happy to help out.

-Zach

I would suggest going with the 31" tires with only 2" of lift. There's two reasons for this:
1) As mentioned, you're really going to be limiting flex to keep them from hitting your fenders. If you do anything more than very light offroading, the extra flex is very useful.
2) Gearing. You have the auto which I believe gives you 3.73 gears but even still, you may lose 5th gear with 33's.

In short, I believe 31's will allow you to keep your speed up, as well as work better with the 2" lift even in offroading conditions. If you want to go with 33's, I would suggest a 3" or more suspension lift. (Of course, keeping in mind that once you pass the 3" mark things can get more expensive like requiring SYE, etc.)

Finally, the bigger and heavier the tire, the harder it is on the not-so-robust D35 rear axle. By picking smaller tires you put less stress on it and it will likely last longer for you.
