yes, gears have to match front and rear. What axle do you have in the rear? Also just to let you know if you do some snow driving in your area a full time locker can make driving less fun in 4wd as the front end tends to pull you to one side.

a detroit locker is a full time locker, no button, always on. If you want a "button" then ARB or OX. I ran front and rear ARB's on my last TJ.

You most likey have a rear dana 35, see if it has a plastic diff plug. If so I would not recommend any locker without upgrading the shafts to some 30 spline units at the least with that axle.. if you have a metal plug you have the dana 44, and are good to go.

wasn't an attack wbrett. i work with expereinced mechanics that don't have the proper tools and knowledge to install gears properly. mulitple angles are measured to the .001 w/ special tools for meausreing and installing. and the money you spend on gears, install kit, and lockers if purchased aren't cheap and kinda sucks if they fail.

thats all.

Tell me about it, I had my air lockers & gears installed & the front locker is not working after 2 months. The shop is great & they will fix it so I don't have to worry too much bc they will just get it back untill it is right. I am glad I had them do it & not someone that does it in their back yard. Wbrett1027 don't do it unless you are a mechanic & someone who says "is it like a rubber fill plug?" well in my book is not real familiar with working on vehicles Changing oil & doing gears is like chalk & cheese

I agree with Jpdocdave. If you have to ask if you need to install matching R&P gear ratios in the front and rear axles and then ask what would happen if you did not, it's unlikely you're skilled enough on drivetrain/axle work to install R&P gears and the type of locker you're asking about.

Don't take it personally. I have a huge set of tools in a 5' tall rolling cabinet, air tools, a welder, etc. and I do all my own work including repairs/basic fabrication on my TJ... but even with that, I am not skilled enough to install R&P gears. I've been working on my own vehicles for 40+ years, have torn into my t-case, swapped my trannies, converted from a manual to an automatic tranny, installed all my lifts and lifts for others, but I won't attempt to install my own R&P gears. That is a far more complex job than Jpdocdave and I are guessing you think it is.

that is all i was saying, its not personal. jerry said it well, if you have to ask those questions that would mean you haven't done it before, which is fine. that would also mean you don't have access to the few thousand dollars in tools that i've invested in specifically for gear installs.

doesn't have anything to do with your ability to work on cars, or build stuff. wouldn't you wanna know before you find out the hard way?

so sorry if it sounded offensive, was not my goal.

Based on that, you should definitely install your own R&P gears. I guess I'm an idiot for thinking it didn't sound like you were that skilled at such work. Let us know how that works out for you.

Don't put a Detroit in a D35! Its a waste of money and time. Upgrade to a D44 or 8.8 first. You can safely lock the the front though, which is better than nothing.

Axle upgrades will follow. (as you break them)

just put a spool in it, whether you regear it to match or not.

To answer several questions: I had no issues with my ARB's. The front 30 and 33-35" tires does well with a ARB locker, however carry a spare set of shafts as they could break.

The Dana 35 rear axle has a round black plastic fill plug. Sounds like that is what you have. I would not invest in gears and and ARB for it unless at the very least you upgraded the shafts to 30 spline as well as add an axle brace. The better solution is a dana 44 or other larger axle. Figure a used dana 44 that will bolt in will run about $1000-$1500 plus gears and locker.. so $2000-$2500 when all is said and done.

Wow this thread is fun Gears are easy you just take the old ones out and put the new ones in. I don't understand why people make it so hard, and the front and rears don't have to match that is and old wives tale Good Luck

i have an idea, instead of wiring a switch, just use a blank switch in the dash, then weld the pinion gear to the ring gear. just flip the switch when off road.
