Quaife TDX2U001 Tran-X 2 Way Plate Differential for Honda Civic

Quaife TDX2U001 Tran-X 2 Way Plate Differential Honda Civic Type R EP3 FN2 DC5 LSD

Tran-X Honda Civic EP3 - 45/90 (55/90) Heavy

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 differential’s 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).

The TDX2U001 is in effective a -way operational diff with ramp angles of 45/45 and a heavy pre-load (70-75 lbsft). The heavier the pre-load, the longer it will take the diff to 'unlock' once it is locked.

In addition, the TDX2U001 is available with Dual Ramp Blocks allowing the user to change from 45/45 to 35/90 (1-way) disassembly and reassembly of the LSD is required.

Suitable for track days, race, rally and drag. Not suitable for road use.
