Outer Limits 4x4 Board

hey fellas,

in the not to distant future, i will be starting to do bar work for my 75, as it has no bull bar, i may end up making two, one for now to replace that pissy little folded steel bumper which offers no protection, then one when it comes time to do the winch,

i would like to do the winch bar first, but as i dont know the mounting pattern it is a bit hard to work out,


how do you strengthen the bar where the winch sits and where it attaches to the chassis?? as i, having no idea about the winch, would put a plate of 6mm steel bent in a u shape all the way across my chassis rails, and bolt it with 12mm or 16 mm high tensile bolts in a few places(6 or so).

is that enough, ot not enough??

HI Mate,
Hope this helps a bit.

My winch cradle has 4 bolts under tension into the cross member, plus 4 bolts under shear bolted up through the cross member and chassis side rails, so 8 all up, all 8.8 high tensile.

The other bar i have which was a modified arb bar had something like 16 bolts all up again all high tensile.

But its worth pointing out a winch only has 4 to attach it to the bar and that is never an issue.

heres one i built years ago. a bit basic but strong as
it was on a 60 series


cheers steve

cheers fellas, so 8.8 hey, here i was thinking about going 10.2 or 12 lol...

so gathering from those pictures you just had your winch bolting to the other side of the bar??

yep ,pretty standard way of doing it

Mine bolts through 2 bolts each side of the chassis at the body mount or so, and 2 on each side at the front, although I only have 1 of the fronts in each side.

Holds fine with some decent pulls had

Sorry to hijack, but does home made bar work need to be engineered?

not as far i know, unless u got airbags

i used to build bullbars ute and truck, the only ones engineered were 4 FUPS(front underrun protection systems,i think they were called)

should hopefullay be giving it a go within a month. will probably just make a bar for the moment then make a winch bar when i go for a winch

save your self time and money ,build your winch bar .you dont have to have a winch till u can afford it

any photos?

You could modify an old winch bar off another vehicle and fit it to yours.

I chopped up an Ironman GQ bar and used its winch cradle. Havent finished yet obviously (needs crushtubes, bars, etc), but you get the idea.

not showing everything but it might help.



this shows the std bumper / bar mounts.

behind he bar here it bolts from memory into 4 cross member bolts, plus 4 under the cross member, plus 2 into each chassis rail from underneath. struck me as bit of an over kill to be honest.

yeah, i would have thought two per side on the c channel section, and one per top and bottom would be sufficient, i guess i will see what i can do when i take the dicky little bumper off.

cheers for the help and photos guys.

the hanko - what rig is that off??
