The 5000 lb relates to the max you can put on a towball so the bar work could be stronger
With a rated pin the 6mm box the tounge goes in is adequate. With 4 bolts spread as they are and the plate on the other side of the chassis it should take the load but 8mm would of been better It might deform but shouldnt break

A strange part of the modification rules in NZ is you are allowed to weld to the chassis for a towbar but no other reason.

Just my own view here, but this thread IS about rear recovery hooks(points).....

Was meaning that this was a good place to discuss it, you are making it a recovery point aint you
What engineers are you planning on using for the chassis work? I have a few small bits i want to get done for future mods on my 4bie and it was suggested to get a REAL engineer to do it as some chassis are hardened steel and normal welding can ruin that.
