D44 winch bumper
Hi guys i've just bought a D44 winch bumper and it is a really solid piece of kit. The only thing i notice is that it has just the normal 2 bolts each side to mount it on the chassis. Will those 4 bolts take the strain of the winch when winching? Should i look at welding brackets to bolt in onto side of chassis as well?

Those 4 bolts are more than enough, you'd be amazed how much they could take, I really wouldn't bother strengthening anywhere else, besides, if Devon 4x4 supply the bumper like that then that's the way it's supposed to be, they really know their stuff Thumbs Up Optimists say the glass is half full..

I've seen people install M12 bolts. This means you'd have to tap the captive nuts to that size.. Solved the bowel problem, working on the consonants...

8.8 M10 Bolts holding the bumper on.

A brief google suggests that they will take 3T plus in shear. I'm not a mechanical engineer, but I'd assume you have 4 bolts, so 8 bearing faces (top and bottom) allowing for 24T of Strength in the bolts. I suspect it would start pulling out of the bumper and chassis legs first!

^^ they wont be under equal stress so 24t can only be thought of as an ideal. How much stress a single bolt goes under during a worst case scenario is the number you need to compare with the 3t number you looked up. That's a harder number to come by Thumbs Up Solved the bowel problem, working on the consonants...
