Hi-Lift Mount on ARB

[Brentbba]

I put together a slight variation of the Hi-Lift jack mounts we've seen on ARB bumpers. I already owned Christo Slee's Hi-Lift roof rack mount, but given the weight of the 60" jack, I wasn't very comfortable with it bouncing up there.

Took a couple of 5" bolts and several nuts as spacers in conjunction with Slee's mount and I have a perfectly good ARB jack mount.

Did someone steal your winch?

I did something similar with my TJM bumper using roll bar brackets:

LOL! I only wish I had the funds. M1200 best price I've seen searching the net is $1015. No winch yet.

Snorkle is likely next and then perhaps a lift. Winch will be waiting awhile methinks.

Good job looks nice.

Looks good, but you don't leave the hi lift there on the highway, do you?

Hadn't thought about it, but probably. I can see how it could easily become a decapatating projectile in a front end collision tho!

Usually I bolt the hi lift up front the night before we hit the trails. However, I've been a bit lazy lately and its been on the bumper for a while. I've had no issues with it up on the bumper while flying down the highway. I did have some minor rubbing against the bumper, but I zip tied a piece of neoprene from one of my old wetsuits and eliminated the rubbing.

I might try to make some room for it in back once I complete my custom storage box and drawers.

Is it only me or in an event of a accident - is anyone else worried that the mount might break off and head for the windshield?

It is convenient where it is mounted though.

I think that was WOB's point precisely. Probably wouldn't take much to shear whatever bolt or weld you use. Those jacks aren't exactly light weight.

Mando, don't be such a whimp .......Hey come over and see Navid's new 40!! We went up to Gary's (mudrak)on sat.. picked her up....Oh, Brentba, looks good, oh and get the lift next bro.......

that being a projectile is one thiing but what about gas millage.. I mean thats cant be aerodinamic.

.....and our trucks are aerodynamic to begin with?

You're right, it's something to consider where we mount these things. That's why I try to only keep it on the bumper only when I'm going offroad.

However, a hi lift or anything else that's heavy is a "projectile-in-waiting." Whether the hi lift is bolted to the front bumper, bolted to the side of a roof rack or even inside the roof rack basket it's potentially a projectile in an accident.

Also, keep in mind if you carry a spare tire, jerry cans, tools and etc on your roof rack, they too are "projectiles-in-waiting" given their mass/weight. I guess the best we can do is to bolt or strap them down as best we can.

Mine is just mounted in the same place with grade 5 bolts, wing nuts, and a few spacers through the holes in the jack. Aerodynamics, did the arb, winch, roof rack etc help in this area, when did we start worrying about aero on trucks that can barely top 10 mpg. Like most other mods the cool factor makes up for the loss. It does rattle a bit and get caught on a branch or two.

I mounted my hi-lift on my ARB bumper with wheel lugs and a 2" bodylift pucks.

Are you guys seriously worried about 2 5/8" bolts shearing under the impact load of a hi-lift? Have you looked at the bolts holding your suspension together? I think it will be fine assuming you didn't use bargain bin chinese hardware. Slap some grade 8 hardware on there, use some coupling nuts for the spacers(less ghetto looking, no offense) and you're set.

FYI, assuming the bolts are made of mild steel, it would take a load of more than 12,000 lbs to shear the 2 bolts. Assuming the hi-lift weights ~40lbs, you'd have to have a wreck causing more than 10G's to snap those 2 bolts. I think at 10G's you've got other problems. Also, a Grade 8 bolt will have a significantly higher shear strength than mild steel.

I wouldn't worry about it.

All that aside, I stopped carrying a hi-lift outside the vehicle due to corrosion reasons. The damn thing was always sticking and wouldn't work right. Now I have it disassembled and throw it in the truck when I'm goin on serious 'wheelin trips. I found it's much easier to store disassembled since the main bar lays flat.

But if it were on a conveyor would it have that much force or no force at all?

I don't feel confident enough in my math skills to trust two bolts to keep me from killing myself or someone else. But, if you say they will hold, I'll go along with that. Please don't hit me head on, though.
