brigzee,
yeah, I didn't address your main question, was intent upon highlighting the difference between static and dynamic load applications.
I guess 4000kg is the most commonly available and roughly equates to the 8000/9000 lb of most
winches, but 6000kg & 8000kg rated extension straps aren't too hard to find on the net (eg from google, so maybe your local
shop does need to lift its game.
The whole rating thing for recovery gear is a bit suss anyway, where non 4WD-specific bits like shackles have a SWL rating derived from their minimum breaking strength divided by a fair safety margin, while all the straps and the like just use a minimum breaking strength.
My hand winch, rated at 3200kg lift, 4800kg pull has a 16mm cable; 9000lb electric
winches seem to get away with an 8mm cable. - Go figure.
That site link that tvl posted above is a pearler.
