get a front recovery point, by all means
but, whats wrong with the tow bar as a recovery point?

It's only rated at 3.5 tonne, put a kinetic on that with 10mph pull before the snatch and your in ripping the tow bar off territory.


you will find that the actual tow hitch has the rating for 3.5 tonnes, the tow bar assembly is rated higher.

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.

My towbar is held in with 6 bolts along the body rails and 2 through the rear panel. I understand the point of SWL but I've seen less adequate fixings on most aftermarket 'recovery' bumpers.

The bolts are at least M12 (from memory - may be a bit larger) - it is also bolted to the rear "crossmember" with a couple  of bolts

The shear strength on one bolt is more than adequate - nevermind 6 bolts.

The frame bends before anything breaks - this then pushes the rear of the car up - which stops the boot opening / closing - depending which way it was :roll:

1 standard grade m12 bolt will take 10 tonnes of force

There would be no chassis left by the time you broke all 12 on an xj towbar
