and the rating is?
Proper recovery gear will have a x3 SWL for towing and should have a x7 if it's lifting specs.
Be interesting to see what the shear ratings are for the 4 (?) bolts which hold the tow bar in is?
TBH they are pretty strong, I had an MU with a 3.5 tonne tow limit which was in a crash with a double axle ifor williams with a hilux on the back, the tow bar bracket bent but it held. Twisted the chassis, but held.
