Description / Condition: Helical LSD Advantages:-
Blackline Helical LSD’s – How They Work The 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 proprotional 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. Note – Helical LSD’s work especially well when combined with modern anti-lock braking systems. Genuine reconditioned part, in full working order. Gearboxes have been stripped, cleaned, inspected and reconditioned with all new bearings/syncro’s. |
This gearbox is sold on an “Exchange basis”. After you purchase you will need to pay a £300 REFUNDABLE surcharge.
We can’t ship your order until this charge has been paid.
Remember the additional charge will be refunded back to you when we receive your old gearbox unit which we can collect.
Please note: If the exchange gearbox is not in serviceable condition i.e a hole in the casing or it has been run with no oil (burnt out) then the surcharge will become non-refundable.
