We have just sourced some fantastic bolts, and deadlock to drastically improve the exterior security on your Defender. It is well known that the hinges with their exposed bolt heads are a particular weak point on the defender, with the shear bolt kit we stock, one of the bolts on each side of the hinge is replaced with a shear bolt, and this then secures the hinge. The only downside being that they need to be drilled to remove them, so that is quite a permanent security solution! We have also sourced a deadlock set for the Defender, one of the only ones on the market, and a particularly smart solution, as you can see from the pictures on the website here. Both of these options will be a good start to improve the security on your Land Rover. Implement them with various other solutions, especially a tracker, and rear window security, and you will find risk of theft of your Land Rover will be dramatically reduced.
