Some of our customers experienced an issue with the OE Lotus / Xpart / Rover oilseals.
Ever since these seals were produced in India, some of them randomly loose small amounts of oil.

We discussed this matter with one of the largest OE seal suppliers and asked them to design an uprated seal which would just do what it's supposed to.. keep the gear oil in the gearbox!

These seals have meanwhile been tested on various cars meanwhile and have proven to actually do a good job.

The smaller seal is for the RH side of the engine (long driveshaft) and the larger seal is for the LH side of the engine (short driveshaft)
