Our Defender windows have been designed as replacements for the Land Rover Defender 90 and 110 and may fit other models – just call to discuss. They are easy to fit if you know a bit about DIY, you will need a drill and a rivet gun. A template is available as an optional extra. The size of the aperture needed is 1057mm x 427mm – which is the Land Rover standard size for Defender rear side windows. Fitting service also available – just call.

We manufacture to original Land Rover quality using original shape Land Rover aluminium profile and locks/catches. Our windows are made using E43R toughened safety glass – Omega Automotive has been manufacturing automotive safety glass and many other vehicle parts for many decades and supplies all around the World to various automotive firms.

Many old windows rattle, leak and are draughty – our replacement land rover defender windows will solve that – in addition if you order the tinted versions you will be reducing glare and reflecting some of the heat on a hot day. The tint is factory-prepared – the glass is actually tinted and not a stuck on film which can peel off – film is not simple to apply in any case as the glass has to be removed.
