Tran-X For Toyota GT86/Subaru BRZ/Scion FRS LSD

Part Number: TDX2E-Quaife
Excl. VAT: £ 715.00 Incl. VAT: £858.00

Availability: In stock


The Tran-X powered by Quaife LSD is a multiple plate limited slip differential

It features two ramp blocks sandwiching two planet carrier pins which sit in the radius between the leading and trailing ramp angle

As torque is applied to the differentials input, the pins ride up their respective leading ramps, pushing the blocks apart and increasing the transfer of torque across the axle
The angle of this ramp determines how quickly this transfer occurs within the LSD

An angle of 35 degrees allows the blocks to be pushed apart more readily than a 55 degree setting, resulting in a more aggressive differential locking action

Plus, the preload setting dictates the contact friction between the plates themselves

The higher the preload, the more rapidly friction increases between the plates, creating a more aggressive locking action

Combined with the ramp angles, the preload allows subtle adjustments to the torque transfer characteristics allowing users to alter the dynamic balance of their car
Typical settings for a lightweight track car would be 45/90, allowing progressive application of power for optimum acceleration

Some Tran-X powered by Quaife differentials feature dual ramp blocks, allowing ramp angles to be changed between two combinations, for example track and fast road settings (disassembly and reassembly of the LSD is required)

We also offer a less aggressive super-lightweight plate setting (preload 10-15 lbsft) for certain road and kit car applications to optimise performance and reduce operating noise
We also now offer a 4-pin trials spec (non LSD) differential for use where strength is vital, but all forms of LSD are banned by the rules of a particular discipline.
