Frequently asked questions

What is a seat diaphragm and what does it do?

A seat diaphragm is the moulded rubber or webbing base under the seat foam that supports your weight and gives the seat its cushioning. On the Discovery 1 and Range Rover Classic, this Genuine Land Rover diaphragm fits under the outer front seat cushion.

Where is this diaphragm fitted in the seat?

It fits under the rear section of the outer front seat cushion, forming the base layer between the seat frame and the foam pad. It's not visible once the seat trim is refitted.

Does this diaphragm fit all Discovery 1 models?

It fits Discovery 1 models built from VIN (V)FA393361 onward, so earlier chassis numbers may use a different diaphragm. Check your vehicle's VIN if you're restoring an early 1989-1990 example.

Which vehicles does the MTC9931 fit?

The MTC9931 fits the Land Rover Discovery 1 (1989-1998, from VIN FA393361) and the Range Rover Classic (1986-1994). It's Genuine Land Rover stock rather than an aftermarket reproduction.
