Remanufactured by Rimmer Bros - Crown wheels are available to the later Girling axle specification only.
To fit a new crown wheel to a Lockheed axle, some modification is necessary to the bolt holes on the carrier to which the crown wheel is to be attached.
Alternatively, a later, Girling type carrier may be substituted.

The crown wheel to carrier attachment bolts must be fitted using ‘Loctite’ or similar thread locking engineering adhesive. (GAC100). The use of the locking washers alone is insufficient. All the bolts must be tightened to the torque of 46 ft. lbs. as specified in the workshop manual.
Use ‘Loctite’ to secure bolt if tab washers are not used

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 drivability. Especially in low grip situations.

Fits:-
Triumph TR3-4A
Triumph TR5-6
Triumph Stag
Triumph Dolomite Sprint
Triumph TC2000/2500

Helical LSD Advantages:-
  • Equal rotational speed to both wheels
  • Torque distributed according to traction
  • Minimal service requirements - no clutches
  • Quick reaction compared to viscous LSDs
  • Gentle and progressive engagement, low noise
  • Easily controlled power take-off and drifting
  • Gears and body manufactured from 8620 alloy steel
  • Direct replacement into stock differential
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 optimized 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 problems there is always some 'drag' on the slipping wheel, however some drivers expertly use left foot braking to partially lock the spinning wheel.

Please note:-
There is a central pin inside the differential.
When fitting to Triumph TR3, TR4 and Dolomite Sprint, leave the pin in the differential.
When fitting to Triumph TR4A, TR5, TR6, Stag, TC2000/2500 - the pin needs to be removed, this requires the differential to be disassembled.
