Blackline Helical LSD's - How They WorkThe Blackline helical LSD's are torque biasing, that is they distribute torque between the wheels, loading more torque towards the wheel with the best traction thus improving performance and driveabitily. Especially in low grip situations.The helical gearing manages the distribution of friction within the LSD. When torque is applied to the helical gear system it creates force that pushes the gear into the differential body, thus creating friction. Increases of torque, increases the thrust force directly proportional to the amount of torque. This allows the Blackline LSD to cope with considerable traction imbalance even under heavy power conditions, as would be the case on exiting a powered up corner. But at low torque conditions the LSD can differentiate quietly and smoothly, thus making the differential very suitable for normal road driving.The Blackline LSD uses the popular parallel axis helical geared configuration optimised for even load distribution. They are designed with a torque bias of 5:1 this means that if one wheel loses traction then the wheel with the most grip can receive five times as much torque as the wheel that is slipping. However, five times zero is still zero, so all these helical LSD's work best when both wheels are 'planted' and some traction is still available on the slipping wheel. In practice this is rarely a problem as there is always some 'drag' on the slipping wheel, however some drivers expertly use left foot braking to partially lock the spinning wheel.Helical LSD's work especially well when combined with modern anti-lock braking systems. THE BENEFITS ARE:Applies equal rotational speed to both wheelsDistributes torque according to available tractionMinimum servicing compared to plate type LSD'sLow noiseControlled power on launches and drifting slidesProgressive engagementEasier car controlOptimum gear tooth design and oil distributionGears and Body Manufactured from 8620 materialDirect replacement for stock differentialThis is a Torque Biasing Helical Gear LSD. These are generally regarded as a nicer road LSD as they have little side effects during normal driving (unlike plate type LSD's that constantly resist differing wheels speeds during cornering) They do not require a special oil. We recommend that the axle oil is changed after the first 500 miles as initially they can create swarf - this is normal and will reduce with use.(NOTE: This is NOT a plate type, viscous coupling or clutch pack LSD) INCLUDES:Assembled Differential Unit ONLYBearings, gears, gaskets/seals etc are NOT included No instructions are includedPicture shows what you will receive if you purchase this item IMPORTANT INFORMATION:Postage: We will endeavour to despatch most items purchased before 3pm the same day (may not be possible on all items following bank holidays/busy periods etc).
