The Importance of Correct Strap Selection
A snatch strap relies on its elasticity to get the stationary car out of is bog. Ideally it will stretch an extra 20% ontop of its initial length to give the correct elastic reaction and 'snatch' the vehicle free.
To get this ideal 20% stretch or very close to it, the snatch strap should be rated between 2 to 3 times the vehicles GVM (Gross Vehicle Mass). Most Compact SUV's have a GVM between 2,000kg to 2,4000kg, so a 6,000kg Snatch Strap is the most suitable size for use on those vehicles.
If the strap is rated higher than 2 to 3 times the GVM, it will not stretch enough. This would dramatically increase the shock forces that occur during the recovery which can cause damage and even catastrophic failure of the strap, other recovery gear, the vehicle and even the occupant. The other way around using a strap that isn't rated high enough can overload the strap (take it past its limits of elastic deformation) causing it to fail causing it to fling back at a vehicle at a deadly rate.
