When put under load, our recovery ropes stretch up to thirty percent- 50% more stretch then a snatch strap (20%). This stretch relieves the sudden jounce commonly associated with vehicle recovery, effectively reducing the amount of stress exerted on a vehicle and its occupants.
Some slack can be left before starting the recovery process with kinetic recovery rope, enabling the pulling vehicle to get momentum and hence gain a much higher pulling force. Since the kinetic recovery rope is exceptionally good at absorbing shocks, it stretches under tension and transfers all the energy gained from the pulling vehicle to the stuck vehicle.
The ability to leave slack comes in handy when the pulling vehicle is in very loose terrain, such as deep sand, snow, or mud as it enables the vehicle to move before it starts feeling the weight of the moving vehicle.
