Description
This differential have different bearing on the differential with larger holes which means it’s possible to upgrade the diff to 30 and 31 splines.
This differential will be possible for use with all Volvo 140, 240, 740, 940, 760 and 960 series.
Tenaci Motorsport also offer upgraded thicker driveshafts for Volvo with 30 and 31 splines.
By choosing 30 or 31 splines for this differential and buying Tenaci upgraded drive shafts your Volvo
will be able to sustain much higher loads compared to OEM driveshafts.
Volvo Original speed ring can be transferred to this differential so that you can speed sensor and ABS.
The differential has an edge where the speed ring can be tapped into.
In cooperation with Peter Schmidt it has been proven that the Tenaci LSD diff has what is required on track to compete in Time Attack.
Niklas Maisaari has also driven well with the same differential with his Volvo 240 in Time Attack.

Ore do you have a paper how to set up the discs / plates to adjust the preload ?
→ There are 3 ways for adjusting the preload.
- Washer: The thickness of washer that we installed is 2.3mm. If the preload is too high, you can change the washer to 2.1mm or 2.2mm that we extra attached with the LSD.
- Spring: We installed 12 springs (maximum) in LSD. If the preload is too high, you can lower the q’ty of spring and install them in symmetrical positions.
- Lock Capacity: If the preload is too high or too low, you can adjust the sequence of plate, below info is for your reference.
