Detroit TrueTrac
Based on the worm gear principal and works like clutch type positraction. Does not wear out, not recommended for tall tires over 33".
Detroit Truetracs are similar in design to the Gleason Torsen(R), only the Truetracs hold up well with reasonably tall tires. They use worm wheel gears that work on the same principle as a worm gear. When the unit is loaded, the worm wheels are forced away from each other and against the case. They develop locking torque by the light friction between the worm wheels and the case. This light friction is multiplied by the ratio of the worm wheel which depends on the size of the worm wheel relative to the size of the side gear. The manufacturer can change the amount of torque biasing or lockup by simply changing the diameter of the gears, or the pitch and spiral of the teeth. A larger difference in the size for the worm wheels and side gears (smaller worm wheels and larger side gears) will increase the lockup force. Increasing the pitch and spiral of the teeth will also increase the lockup forces. Like everything, there is a limit as to how much lockup force is reasonable. Making the unit too "aggressive" will cause tire scrub during everyday driving and will cause the unit to wear out too quickly. All of the feedback that I have received from customers indicates that the unit works very well for mud and snow, while going unnoticed during every day driving. When used in situations like rocky trails where one wheel gets off the ground, the unit will not lock up 100%. Light application of the brakes will help the differential engage more transferring power to the tire that is still on the ground. For extreme situations where the vehicle will have one wheel in the air often a locking differential provides better power transfer to the wheel on the ground.
Detroit Truetracs are designed for medium duty 2WD and 4WD applications. They work well in the front and rear, and are so smooth that there is little or no hint of resistance in the steering wheel when used in front drive steering axles. Like the Gleason Torsen, the Detroit Truetrac does not bang or clunk, has no clutch chatter, does not wear out like clutch type positractions, does not need limited slip additive, and needs no preload or clearance adjustments.
Almost sounds too good to be true doesn't it? The only drawbacks to the Truetracs are their inability to provide lockup 100% like a locking differential can. Although Gleason no longer makes the Torsen differential, the Detroit Truetrac is a proven design that is available for many popular applications. (aftermarket) 1 yr warranty
The Detroit Truetrac was the first helical gear differential ever introduced into the automotive aftermarket as an Eaton brand. It remains the leading helical gear-type limited slip differential in the industry. Detroit Truetrac's proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction. Recognized not only for its toughness but also it's smooth and quiet operation.
Engineered to work efficiently in front and rear axles, semi-floating (C-clip axles) and transfer cases. Power transfer is so smooth, it literally goes unnoticed by the driver - even in front wheel drive axles.
Proven design, low cost and effective performance, all make the Detroit Truetrac limited slip differential the ideal choice for a wide variety of vehicle applications. No maintenance - Just Traction.

|

might not work with large tires
|

I have this in the front of my discovery. it works two fold, as mine is permanent 4wd with a lift it keeps the steering tighter with a lift. This is because i have not corrected the angles on the caster, and the diff gears make the front end heavier. I am running 32's and plan to jump to 35's so we'll see if they hold up to larger tires although eaton says its no good. I have had this front true trac for 5 years and very pleased. Would have to be shown up off road to change it to arb, and even then might not due to complexity of that setup. just drop in and go. cant beat it

I had one of these in my 1997 Toyota (rear diff) 4Runner and liked it ALOT. I have no complaints at all and questioned whether i wanted to go to a Detroit Soft Locker. Just apply the parking brake and the other tire would grab except in the most worst situations. but on the street, you wouldnt notice it until you needed it. i.e slick Texas roads after a rain. Cant say enough about this item. Highly recommended--and i do actually wheel!!!

The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. ,

I don't know what that last comment was about up there, but I have to agree, capitalistic greed will be the downfall of humanity. On another note, this seems to be a pretty good differential, never wears out like a limited slip, and is time tested. If I had the money, I'd buy one.

For the above post. Capitalism is what built this country and kept it strong. Progressives have demonized the capitolist for so long the sheepole fell for their lies. personal wealth creates jobs and high wages, shared wealth creates nothing. Do your own research on the subject people, don't just fall for what the talking heads are trying to push.
