That seems like a reasonable assumption.
Is the winch bolted to the frame at all?

Garrett, That sounds like an exciting story! I seem to remember that guyThe new recover points mounted to the winch tray are working out great. Luckily the only part that bent was the panel that gets discarded when the winch tray is added.....Where where you last Saturday??

this is not true...a winch loads up smoothly to peak pull where a strap or chain(bad idea) causes a huge spike in load exerted onto a recovery point.

If you jerk the crap out of it, I completely agree. If not, it shouldn't be an issue. I've had it tugged pretty hard with no problems so far.
I also have 2 recovery points up there so if I need to be jerked slightly I can double up and spread the initial shock to both instead of just one. That way the load is shared by both crush cans.
I know there are cons to what I did, all I can say is that I thought about them and don't think they're as bad as everyone thinks they are if you don't go crazy using them. I know there are limitations to them.
And definately no chain on them.

Discokayaker, regarding my concern that the CM hooks attached at the winch tray would limit recovery options, you are right that it is probably unfounded. I imagined a scenario where the recovery would be needed from a vehicle elevated quite a bit in front of the "victom". Given that the hooks are mounted below and well behind the leading edge of the bumper I don't want to risk having the bumper take the stress of the vehicle's weight given that the only point it attaches to the frame is the crush cans. But I have not been able to guage what the actual clearance angle is. One response indicates that it caused only damage to the "knock-out" plate where the tray would be installed.
Any other personal feedback is appreciated.

I am trying to understand something here. Its safe/strong enough to mount a winch on there but not safe or strong enough for a recovery point?
Last time I looked at the crush cans on my ARB they were engineered to crush not stretch. I cant possibly understand under proper and safe recovery how a quality recovery point that is installed properly on any bumper would have an effect on the crush can itself. Given the mentioned circumstances here the thickness in crush can material alone would have me worry about the mounting point on the frame more than anything else.

Ron. . .on the TJM bumper the winch is mounted to a separate tray that is bolted directly to the frame. Most will then mount recovery points to this tray. Don't know about the ARB though.

The ARB winch box is integrated in the bumper, not seperately attached to the frame. From reading this thread, the TJM isn't. I'd have to take a good first hand look at the TJM to see if I'd add recovery points to that bumper.
As for the ARB, I'm perfectly content with the recovery points I mounted. I completely agree with you Ron.

Ryan,
I am thinking about the TJM (I have been waffling on a front bumper for months). Meet your expectatoins? Also, how does the approach angle compare with the ARB?
BTW, I am also thinking that the crush cans should be alright since winching is pretty similar to pulling so long as the guy pulling doesn't 'make a run at it'. Shane just had his ARB yanked on reasonably hard this last weekend with no ill effects.

Does anyone know where I can find a pic of this seperate tray mentioned for the TJM? I can't seem to find one anywhere on the web.
I may be able to pick up one used locally and need to know what it looks like so I can be sure it will work with a TJM (T17) - http://www.tellico4x4.com/catalog/product_info.php/cPath/85_2339_1115/products_offroad/15251.

I already own an M8000 - just need a bumper/mount to go with it.
Thx!

EDIT: Are those pics from Hollister Hills? If so, I spent many a day out there before moving from San Jose in May last year. Fun place for a "Pay to play" location.

I have a D1 with a newly installed airbag compatile ARB. On that model the winch basket mounts to the frame with the same bolts that mount the cans on. I would then say that it is mounted to the frame. Other models may vary.
Recovery point wise, I used to have two JATE rings mounted on the frame. With the ARB and the winch tray, the JATE rings do not have enough clearance between the hinge points. Maybe a little judicious shaving might get them to fit again. But that is about 3/8 to 1/4 inch of metal to remove frome the JATE ring. How much will that compromise their integrity.
My next favorite idea would be the hooks mounted to the frame. I know I am walking into the fiery furnace here, but an open hook just doesn't look as strong or as safe as a closed loop. So until someone bludgeons me with facts, they are not my favorite.
Mounting the recovery points to the front of the bumper looks cool, and is sure convienient when buried up to the ... bumber... in mud, but these are dependent on the streangth of the cans. Objects that look, and may operate like two accordions. )If you can push them, you can also pull them.), and are designed to... well, FAIL. that is the whole reason they are there. I don't mean that the cans would break, but they could stretch. This could ad inches to my Disco's overall length, and ruin the already discussed "lousy" approach angle.
I guess I'll keep filing down my Jate rings, and avoiding places I know will require recovery for my truck.

Ryan,
Just curious if you had found a good place to put a recovery point on the TJM bumper. I am getting antsy about getting a new bumper for my rig, but definitely want good recovery points.

I actually haven't done it yet due to a major financial hit (moving. ugh), but I decided that the best way would be to get the winch mount (~130 or so), and put the hooks on it.. it seems like that is what most people are doing with the TJM bumper.. i'd prefer to just have a mounting point for two d-shackles on the front of the bumper, but I think the alternative is a stronger method.
