Thomas Performance Ltd, Land Rover Parts and Accessories.

Adrenalin 4x4 Ltd was founded in early 2009 by owner and Off Road Motorsport enthusiast James Britland.

The famous Adrenalin pedal locks are now more secure than ever. With new features such as adjustable slider for best possible fit, ultra-bright LED warning light and model specific design make the Adrenalin lock the one to have. Our Mk2 lock received a 5/5 security rating from LRO magazine back in spring 2011 issue. Not settling for average we went back to the drawing board and listened to user comments to further improve the design for our MK3 version. We are the original designers of this type of lock and we have constantly looked to improve our design throughout the years. Our new mk3 lock is without a doubt the best fitting and most secure pedal lock on the market.
