Sliding Side Windows for Land Rover Defender Puma/TDCi (50/70 Radius) - PAIR

Equivalent to Land Rover part numbers MWC4734 RH, MWC4735 LH.

Manufactured to the same quality as our standard dark tinted windows, these windows have 70mm radius bottom corners to fit the unique internal trim on the new style Puma TDCi Defenders.

DO NOT PURCHASE THESE if your defender is 200/300 TDi / TD5 with factory fitted windows, the 50mm PRE-Puma/TDCi version is here.

If your Defender is a hardtop and does not currently have rear side windows then either of our 50mm or 70mm side windows can be fitted irrespective of the year of your vehicle.

If you have a panel van Defender either 200/300 TDi / TD5, and you are deciding to convert it into a Puma/TDCi style and planning on having Puma/TDCi internal trims then you may choose to use these windows listed here. However, if you are deciding to use TD5 internal trims then please purchase the TD5 side windows with 50mm radius bottom corners here.
