I'm planning to upgrade my gears (from 3.07 to 3.73) and get a locker installed at the same time. The kit comes with an automatic detroit locker. I've read that these can cause mild handling quirks in my jeep on the pavement. Does anyone have any experience with this? Is this going to be a major problem? Is it worth it? Any and all comments welcome!
I don't know anything about the lockers, but I would suggest considering a 4.10 or even a 4.56. I know guys who have gone to a 4.10 and didn't feel they went far enough. I have a 3.73, but I also have the super torquy 304.
It's not so much a labor of love as it is shear determination.
Thanks, I thought I would stop at 3.73 because this jeep also is my basic transportation, and I still need it to be a prety good street vehicle. I'm still uncertain about the locker. It sounds like it will definately make it more trail worthy. My jeep only has a 2" lift, so I'm hoping it won't be too bad on the highway. Any other thoughts out there?
I have Lock-Rights installed on my 92 YJ. (both front and rear). "Cjeep" is right, you have to get used to it. Once you do, it's perfectly acceptable. The corner-handling is different as the torque is send to the wheel with the most grip ( which means the inner wheel in a corner, the complete opposite as with an open differential!) I drove it 750 miles to the south of france on the highway, no problem! And above all: off-road capability is DRASTICALLY improved. The only thing you can have better is ARB air-lockers front and rear. In that case, on-road handling is unaffected.
Thanks everyone for your input. After going over everything, I'm pretty sure I'm going to go ahead with the locker. I spun the tires a few times on my last off road outing, and I think having the locker will make going off road a lot easier and will be worth dealing with a little street rudeness.
You really should reconsider the advice on gears. If you're going to spend the money on gears, then you might as well get at least one additional turn out of the driveshaft. Meaning a gearset that's at least one number higher. Otherwise, don't bother wasting the money on the gears because the performance to cost ratio doesn't cut it. I understand you want the street performance. I'm a bit on the more extreme side on ratios, but my Jeep is a daily driver, 50 miles roundtrip everyday. I'm running 5.13s with 35s right now. Pick your gear ratio carefully and make it relative to the tire size you plan on running and you'll get what you pay for.
