just seen some rings which sit on top of your bumper, bolted through to the chassis ends..think there from a series..are these anygood? i see one of the contributors to the 4x4 magazine has them on his td5 90

I had them on my series - I uprated the bolts to M12's 12.9 tensile, Stole them then and put them on defenders winch bumper for easier access recovery points because front Jates can be pain to get at errrmmm photo somewhere...
They would be used in pairs with my harness. For front pull the rough math kind of works out with large safety margin for those bolts at that angle (part shear part tensile load) ... but don't ask me to recite how now though!!! The bumper mounts will fail before they do.

Definately wouldn't use this sort of bumper for any recovery apart from road towing. Some of my guys tried it once with a bellied out Wolf. Ended up with a V shaped bumper. They all found out why jate rings are fitted front and rear to military spec Land Rovers!

Not for recovery funnily enough. JATE = Joint Air Transportation Executive. and JATE rings are provided for Air transportation only. Though I've never heard of a forged JATE ring snapping. whilst been used for recovery. And I've used them on all my vehicles.

Speaking from experience they tend to bend rather than snap when under extreme load. However, never ever pull sideways on a JATE ring, because they literally tear in half when the bolt goes through
Suvvey:
JATE rings are certainly secure enough when used for their original intended use :cool:
Or I'd certainly like to think so next time I'm standing under one of these ;)
Litch:
D-rings on top of the bumper are the way to go, they were the original recovery point on Series LR's and the MOD fitted them to all S111's. I have been using them for over 20-years (I currently have a pair on my 90) and think they are excellent.
JATE rings are very strong but if you are deep in the gloop then the last thing you want to be doing is rumaging around below the bumper to find the attachment point. D-rings are mounted above the bumper line and use the bumper fixing points so the weakest point are the HT mounting bolts and the strength of the chassis, nothing else. Anything else sticks out the front and requires the bumper to be strengthened accordingly.
If you were interested I have a brand-new pair for a 90/110. The mounting plate on the early Series items makes them too long for the later vehicles however the later D-rings CAN be fitted to Series vehicles.
