Price: $529.00
Pros: Aggressive and solid engagement, no clutch packs to wear out, invisible on street in 2wd.
Cons: Expensive and still and LSD, not a locker.
Recommended? Yes

Comments: I've had a couple of these. They are the best limited slip units if you don't want a locker. They engage quickly and tight, and last nearly forever. Expensive that's about it.

Price: $1,000.00
Pros: to early to tell just got 1-16-2012
Cons: none yet
Recommended? Yes

Comments: To early to tell pros and cons yet to early to tell just got 1-16-2012. Please email me and I can reply on how they perfrom over the course of the next couple months

Price: $350.00
Pros: stronger carrier than stock, seemless operation
Cons: not a locker
Recommended? Yes

Comments: stronger carrier than stock, seemless operation, good choice for a daily driver since it is not a locker

Price: $500.00
Pros: It's a LS Dif. Great for snow and ice. No clutch plates to wear out and replace. No need for air or cables.
Cons: If you lift one side the other doesn't work (unless you hit the breaks)
Recommended? Yes

Comments: I want a great snow/ice option. This is better than an open dif, lunchbox, or selectable for road conditions. I'm very happy after 6 months. (and I don't even have to do anything for it to work all the time) With my lift and superflex I've never had 1 rear tire leave the gound off road. (I'm not rock crawling much either)

Price: $529.99
Pros: They Lock, Automatic
Cons: Not the Best but working so far
Recommended? Yes

Comments: Never had any other to compare to

Price: $400.00
Pros: quite and awesome for mud and sand
Cons: None so far
Recommended? Yes

Comments: New ones are improved with twice as many helical gears and fine thread bolts.

Price: $450.00
Pros: Quiet
Cons: none
Recommended? Yes

Comments: Bought it because it has no clutches to replace.

Price: $400.00
Pros: Great street manners. Excellent snow handling. Solid traction improvement for general trail riding. Durable full-case replacement diff for D35 users. No clutch packs to wear out. Brainless, simple operation with no switches, air lines, cables, etc. Standard diff maintenance schedules and procedures. It works great at what it is and within a carefully defined niche application.
Cons: Only available in 27 spline for D35 axles. Not recommended for rock crawling or where tires are lifted often.
Recommended? Yes

Comments: While some don't like LSDs of any sort in Jeeps, I have greatly appreciated these LSDs. I have them installed in each axle and they have been flawless for the nearly 6 years I've been running them in the Northwest. Traction is so good fellow club members don't believe I'm running LSDs and not lockers. Operation is exceedingly simple: just drive. Because of the excellent road manners in dry, wet, and packed snowy pavement these are a great traction diff for a daily driven rig or one that sees significant road time going to and from the trails, and a diff I'd take over an autolocker any day. That said, they're not good in rock crawling or when you're lifting tires a lot on the trails. Still, some judicious brake modulation can get the LSDs to hook up if you lift a tire or hit a very slick section and get you rolling again. It's a very similar technique used on first gen H1 Hummers that use a similar gear-based torsen-style LSD. When I first installed these there were limited options for 27 spline upgrade shafts for the D35. But with the chromoly shafts and especially the Superior D35 c-clip eliminator 27 spline kit these diffs would make a nice upgrade.

Price: $225.00
Pros: locker
Cons: locker
Recommended? Yes

Comments: good locker, it locks the rear axle....

Price: $500.00
Pros: rear locks when it is supposed to . Doesn't chew up tires
Cons: none that i have found yet
Recommended? Yes

Comments: I paid to have it installed because i have been in a couple of trucks / cars where people who said they knew what they were doing did their own and then they howl or just lock up and slide off the road at 35 mph not fun worth the dough imho i also spent a little extra and had new bearings races and seals done on my 8.8 should last forever lol ill probably get hit by an old lady in a parking lot as soon as i get out on the road .

Price: $499.99
Pros: Works great no slip
Cons: Lots of noise after it warms up
Recommended? Yes

Comments: Works as advertised. Not very noisy when turning but after it warms up it clunks hard when going into gear. Am told this is normal operation though.

Price: $350.00
Pros: easy on the road
Cons: doesnt lock up very quickly offroad, takes awhile
Recommended? Yes

Comments: its great for light offroading, but once you get one tire completely off the ground it does nothing, and even sometimes when they're both down it wont lock untill its been spinning for a long time

Price: $500.00
Pros: Great traction. Always on. No friction discs. No additives needed.
Cons: A little squirrelly on asphalt at first.
Recommended? Yes

Comments: I have True-trac's front (D44) and rear (D60) in my TJ. Great traction. I thought I might regret not putting a locker in the rear but the True-trac has proven me wrong.

Price: $450.00
Pros: Quality product
Cons: has helped one tire in the front wear away faster then all others
Recommended? Yes

Comments: Great in the dana 30 in the front of my jeep would recommend adding switch able hubs and frequent rotation of tires. awesome off road performance.

Price: $450.00
Pros: Transfers power great.
Cons: It's never going to be the same as a locker.
Recommended? Yes

Comments: If i had a lower fist gear i could get away with not using 4wd most of the time, it's really amazing how far i can get in 2wd now. My first test was to start one wheel on pavement and one in gravel then floor it and the tire in the gravel barely lost traction, i could feel the power transfer almost instantly.

Price: $348.00
Pros: Great product havent broke it yet
Cons: none
Recommended? Yes

Comments: If want to get where you want i would buy a locker

Price: $200.00
Pros: Great upgrade
Cons: haven't had any yet
Recommended? Yes

Comments: This is a great addition to the D35 w/ 4.10's. I'm able to rock crawl on fairly intermediate stuff. The pic in my profile is from the PA Jeep show and it came in handy. I have yet to have problems with the locker yet. Makes a huge difference.

Price: $475.00
Pros: Long lasting, clutchless, limited slip. Aggressive and reliable engagement.
Cons: Whines sometimes in front diff on road.
Recommended? Yes

Comments: This is an amazing limited slip. Had it on front Dana 30 in my XJ for 7 years. Continues to work flawlessly in low traction surfaces. Not quite as tight as a locker, but you know it's kicking in when it needs to. The gear driven design is bullet proof and flawless. Kicks butt on factory LSD's. Put one on my WJ too. Same results.

Price: $1.00
Pros: Works good, lasts long time, no clutches to wear. No price because I received it as a gift.
Cons: With the truetrac in the front, the Jeep requires a firm hand at the wheel when driving on slippery roads. It's perfectly safe, you just have to stay on top of it when you are on the throttle on the ice.
Recommended? Yes

Comments: If you live where the roads get nasty, and want to enhance your front axle, this is the differential to buy. Lockers are not safe on winter roads, and clutch pack LSDs are no good in the front because of the pre-load. Selectable lockers like the ARB or the Ox are fine off-road, but you won't derive any on-road benefit from one. The Truetrac is great off road, and also helps on slippery roads, while still being controllable under street/highway conditions. Yes, you will know it is there, and yes, you have to stay on top of it, but it's safe and easily controlled. It's really only noticeable when changing lanes with snow and/or ice bermed up between the lanes, especially if you are on the throttle.
Mine's been working flawlessly for over 8 years, and well over 80,000 miles.

Price: $200.00
Pros: Better than an open rear
Cons: Terrible under stress
Recommended? No

Comments: Its good for light wheeling but when its put against something & torqued or the JEEP is flexed right out it wont work like it should
