i recently picked up a 91 singlecab, and wanted to mount an m6000 i have on the front of it. found a cool old school winch-plate bumper for it on craigslist. this thing is made of a 1/4" mounting plate, with 3/16" diamond plate steel shaped like a flat on top step-bumper. i figure its around 75 pounds. add in the winch, and i think i'm getting close to 150 lbs.
i'll add some pics of the mounting brackets tonight, but it looks like there are 3 holes on each of the two sides to mount to the frame rails. thats it.
i don't think i'll have anymore weight than i had hanging off the frame rails of my zuk with an arb, but i see some rigs with added braceing across the frame rails.
wondering if i'll need to do same. this is a light duty winch, that will see very limited use (if any). just want some opinions

 

I don't think its a problem for your light duty usage. I have a tube bumper and a Superwinch and all i did was upgrade to heavier duty t-bars. You can crank the stock ones up, but the ride will be harsh and the CV angle will be higher. Mine are Rancho 24mm set at very similar height as stock was.

If you choose to go with heavier duty t-bars, do some homework. Too heavy (several OD's to choose from) will give you the same harsh ride as the stock ones cranked up.

 

You'll be fine I have an ARB with an M8000 winch and 2 offroad lights on the front of my 4Runner on stock torsion bars.

 

You're fine. The 6 holes probably line up with the 6 factory holes on your front end. Just use quality hardware and forget about it

 

I have a TJM front bumper, budbuilt skid plate, and a smittybuilt XRC8 winch on stock suspension... you're fine.

 

thanks for the quick replies, i figured it would be ok. heres some pix as promised

 

Take that sucker to the self-serve sandblaster, a good couple coats of primer and paint then she'll be good to go.
I don't know how much my ARB with a 9500lb warn winch weights but i'm sure it's up around the 120-150lb mark.
You can always adjust your torsion bars if need be.
Make sure you use as many of the big front mounting bolts as possible.

 

Looks like a beefy bumper. If you plan on doing any heavy winching, I would consider plating the front of your frame so the nuts dont pull out.



4xI and Addicted Offroad both make plates, that will add the additional top hole to utilize all 6 mounting holes on your new bumper.

 

After my last post I looked at that bumper again.
I would seriously re-enforce that bumper.

Is the piece that bolts to the bottom of the frame rail even connected to the piece that bolts to the front of the cross-member?

I would cut off the piece that bolts to the bottom of the frame rail and beef that up. That's where your truck's tow hooks are and where a lot of strength is. The front of the cross member isn't really that strong. I would plate the cross member as mentioned in the post above.
A piece of angle iron between the two lower mounts would add a lot of strength as well.
Check out the mounting for the ARB bumper or any other aftermarket bumper (trail gear, warn, Wab-Fab,...) and see how they mount up to give you some ideas of how to beef up your bumper.

The M6000 is a little on the small side for these trucks. It'll work but if you really get stuck and really need some muscle to haul your truck out of a bind, your winch might come up short.
BUT, an easy fix for that is a snatch/pulley block. You can pick one up at any 4x4 shop. A tree-saver (anchor strap) and shackle paired are needed to use the snatch/pulley block.
With that you'll have double your pulling power, in a straight pull. Cheap insurance and it'll pay for itself the first time you use it. (Off-road tow truck bill vs snatch/pulley block setup).

 

thanks, i got the bumper back from the sandblaster, rattlecanned it, and tried it on. just not happy with that arrangement. called 4xinnovations today and ordered the weld-on frame brace. i know its only gonna see light (if any) duty, but that frame area where the threaded bolts are seems very soft. the extra brace material will make me feel better.

 

looks like its tipped down a fair bit. Try to mount it as high as possible Won't look as funny and will give you more clearance.

 

Looks much better with some paint on it!

 

Beefy! More pictures!

 

the way it mounted up, i was only able to use 2 of the bolts on the front of the frame, and two of the bolts on the bottom of the frame rail. when i get the frame reinforcement rail, i will drill 2 more holes in the bumper, using the frame brace as a pattern. also, my truck doesnt have the top mounting bolts on it that i have seen on other trucks. i will be able to bolt the top mounting holes to the frame reinforcement plate. hope that makes sense. pictures to come ;-)
