Torque Biasing Limited Slip Differential

The key features are:

  • Fully automatic, needs no driver input
  • Totally transparent on road, i.e, no unwanted adverse effects
  • Only comes into play when one wheel looses traction, i.e, a difference in wheel speed
  • Enhances the traction control as it multiplies the bias load created by the braking effect of the traction control
  • Needs no adjustment as the gears compensate for any wear that takes place
  • Only available with 24 spline side gears

These Torque Biasing Limited Slip Differential works best with a good quality Mineral based oil, we do not recommend synthetic oils, friction additives / modifiers and not required.

The Torque Biasing Limited Slip Differential is a ‘Helical Gear’ type LSD with six gear pockets.

The helical gear Torque Biasing Limited Slip Differential has many advantages that overcome the objections to other designs. There is a minimal pre-load necessary to engage the gears but this does not cause excessive wear or harshness, the helical gear type is virtually invisible to the driver on normal road use as the gear/pocket friction simply does not occur.

The Torque Biasing Limited Slip Differential works with six sets of helical gears, mounted parallel to the axle, each side ‘sun’ gear drives six helical gears, these mesh with six corresponding helical gears which in turn drive the opposite side ‘sun’ gear. The important factor is the fact that these helical gears are mounted in ‘pockets’ in the center carrier, so any radial load on the helical gears causes them the press against the side of the pocket creating friction. This is why we use six pockets as opposed to three in another well known brand, more pockets more friction and better Torque Biasing effect.

One of the drawbacks of the Torque Biasing Limited Slip Differential is that it is always necessary to have some load on one wheel per axle. if there a no load situation ie cross axle the wheel with traction would only see approx three times the load on the wheel with no traction ie nothing!!. To overcome this, as stated earlier, the Torque Biasing Limited Slip Differential is fitted with some preload springs to provide some loading to the side with no traction in the event of a cross axle, where this pre-load is not providing sufficient traction to the other side then one favorite trick is to apply a small amount of left foot brake whilst applying more throttle. This maneuver fools the diff by providing load to the non-traction side which is multiplied by the Torque Biasing Limited Slip Differential (approx 3:1) to the other side, the loss of drive attributed to the brakes which are acting equally on both wheels is overcome by the additional throttle. In a car fitted with Automatic Traction Control this braking all takes effect automatically and the Torque Biasing Limited Slip Differential provides additional traction by multiplying the ATC effect.

The Torque Biasing Limited Slip Differential can be fitted in the front or the rear, in the rear you will not notice its there during normal road driving, in the front it will make the steering self center a little more than normal when coming out of a corner but this is only very slight and will lessen within the first few hundred miles and also you will find you automatically adjust to this feeling very quickly.

So why use an Torque Biasing Limited Slip Differential instead of a locker?? Basically when driving on a low traction surface. for example sand, snow, or even wet grass rather than have a locked diff which can ’cause’ loss of traction for example when cornering as both wheel are forced to travel at the same speed, one wheel typically breaks traction allowing all the drive to the other wheel which will also break traction. The Torque Biasing Limited Slip Differential will allow wheel speed difference but at the same time will always try to equalize the torque to each w
