What do you all think of this system?Powertrax
Here is more info I found:http://pacific.telebyte.com/allanw/b...fo/locker.html
This guy states:

Trac-Lok: Made by Dana/Spicer, This is the weakest limited slip available. Wears out quickly, usually under 30K miles (in my experiences anyway). Hardly to not noticable on the street or in the dirt. PIA to rebuild, spring retainer clips prone to break wreaking havoc with diff internals. Available for Dana 44 (30 spline) & 60 (30 & 35 spline). This was an IH option. The owners manual calls for 2/3 oz of limited slip additive for each pint of gear oil.

Powr-Lok: Made by Dana/Spicer, also briefly explained above. Arguably the strongest limited slip available. Lasts well over 100K if proper oil is used and changed per service manual. Set up in stock form not very noticable in turns or icy conditions. Can be adjusted tighter for more positive performance but then is pretty noticable in turns/ice. Easy to rebuild. Almost as expensive as a Detroit Locker to buy new. Available for Dana 25, 27, 30, 44 (all spline types), 60 (all spline types) and 70. This was an original IH option.

TrueTrac: Made by TracTech. A gear type limited slip. No clutches to wear out. Limits slip by binding gears. Early versions used two gears and tend to break easily. Current version uses three gears and is fairly bullet-proof. Hardly to not noticible on the street and very effective off-road, but in the tradition of limited slips, if one tire has ZERO traction (like in the air) it will not transfer torque unless you 'fool' it with brake application. Available for Dana 30 and 44 (30 spline).

Lock-Right: Made by Power-Trax. A automatic locking differential that replaces spyder & side gears in an open diff. Weak point is it uses stock carrier and single cross pin. Special hardend cross pins are available and recommended by Power-Trax for hard-core/big tire use. Very noticable on the street, especially coming out of turns on the throttle, can be tricky for the inexperienced on ice. Noisy when locking and unlocking and may be hard to unlock on short coupled rigs like CJ's. Available for Dana 30, 44 (19 & 30 spline) & 60 (30 & 35 spline). I've heard they also have Dana 25 & 27 versions, but my catalog doesn't show a listing for those applications.

Detroit EZ Locker: Made by TracTech. Virtually identical to the Lock-Right. So much so that federal court has ruled TracTech must pay royalties to Power-Trax, still they tend to cost less than a Lock-Right. TracTech recommends not to use with tires over 32". (Probably because they'd rather sell you a full-on Detroit, IMHO.) Availibility same as Lock-Right.

Detroit Locker: Made by TracTech. In Dana axles, it replaces the carrier. Has equivilent of 2 cross pins. Can be quite noisy when engaging/disengaging. Very effective, like a spool when locked. Very bullet-proof. Driving characteristics like Lock-Right. Available for Dana 44 & 60 in all splines.

Detriot SoftLocker: Made by TracTech. Virtually the same as a regular Detroit Locker, except has Belleville springs to soften shock loads to axles and thus quieter operation. Available for Dana 44 & 60 in all splines.

ARB Air Locker: Made by ARB. A manual locking differential, it also replaces the carrier. When 'off' it is an open differential with all the charicteristics of the open design. When 'on' it is a spool and offers no differentiation. In front axle applications, it may have to be turned off to negotiate turns if suffecient slippage is not available. Pretty strong, but not quite as strong as either of the full-on Detroits. Most expensive unit. requires an air compressor to operate. O-ring failure is not uncommon, rendering the unit open. Available for Dana 30, 44 (30 spline), 60 (30 & 35 spline).
