Custom Front Shackles
 
I built these tow hooks in the machine shop i work at using 3/16" diamond plate and 1st chain supply 3 1/4 ton shackles (i think cant remember). I built these using a 6'x9' Multicam plasma table with Enroute3 cnc program and a Miller welder. let me know what ya'll think. tell me any flaws you may see.

Are you planning on actually using them or are they just for looks?

If you are wanting to use them, don't. They are an accident waiting to happen. There needs to be more structural support for them to support any load. I'm not a physics major so I cant help you with specifics, but just based on common knowledge, some extra support would be needed.

If you are just going for looks, then they look good. Great job!

Do not put any load on those shackles. Your first mistake is using shackle that has a working load limit (WLL) that barely exceeds your GVWR. A WLL is rated under a series of conditions that are almost never met when towing or pulling a vehicle out of the mud. Also, if you are towing a vehicle under circumstances other than straight and level across pavement with all four tires inflated properly, the load on those shackles will be far greater than the GVWR. Especially when stuck in the mud, but that’s another discussion all together. Second mistake is using diamond plate steel that is not rated anywhere near the rating of your shackles. When you mix rated and non-rated hardware, the rated hardware with stamped working load limits must be the weak link in the chain. Best case is to have all your WLLs match, but in the real world that is sometimes difficult. This brings me to your third mistake, using non-rated bolts to secure the steel to the frame, and by only two points per bracket. On the bright side, at least your bracket is welded together. I have seen some similar attempts at tow hooks where screws or even pipe solder was used instead. You did a great job in the shop fabricating them, and they look great. But someone is likely to get seriously hurt or killed if you were to ever use those. And since you made them yourself, the liability for that accident would fall on you alone.

Look awesome... Just don't ever use them.

Wow! he got one broken in heheheheh lol.. Just don't use them man..

Please don't use those!

At least you have the fabrication skills to make something like that, why not try matching what Saguaro 4x has done in their design?

i really respect the concerns and helpful hints. took them off and redone them with support. looks are great tho. i am redoing them in 1/4" heat treat steel. would repositioning them be better? on front cross member where stock ones are fixed? i am up for anything and want the criticism. seminole-3 and ryorde i greatly respect the concern. as of now i wouldn't be using them but for looks as of now. just wanted to see if i could build them.

i took out the spacers and making it flush against the beam and lengthing weld nut bracket inside the beam that attaches to the bracket. going to cure the metal at 500 degrees for 8 hours and scorch. in regards to the 3 1/4 ton shackles and them not being to my gvw....isn't 3 1/4 tons = 6500 lbs? isnt the 05 JEEP GC Laredo GVW 5900 lbs. just curious.

Heat treating isn't going to help...you need waaaay more material.

I have a lot to say on these but i'm not sure where to begin...While you are right that the d-rings are able to hold the weight of your vehicle in a flat tow situation, you would not probably want to use them for getting un-stuck from mud or a similar situation. On the other end though, they would need to be attached to something structurally sound like where the factory tow hooks mount or the Saguaro shackle kit mounts. I would take a look at their website and read about their shackle kit and their mounting instructions to get a better idea. Also, heat treating will only prevent your steel from warping, it won't make it any more structurally sound. Where you are mounting your d-rings to also needs to be thicker. I'd recommend stacking 3-4 pieces of 1/4 steel together and welding it together then grinding it down if not just getting a straight piece of 3/4" or 1" steel and cutting it and grinding it down. this should then be attached (welded) to your mounting bracket which I think the choice to use 1/4" is wise. I also think you should use grade 8 hardware and 3 bolts if you can to give it a more secure mounting and prevent them being ripped of while pulling anything. They definitely need some work before ever being used but it looks like a great effort!

Yes 3 1/4 tons is 6500 lbs. I thought your GVW was higher. Mine is 6800 lbs. Heat treating will help, but the real problem is surface area contact between your bracket and the frame of your Jeep as well as the number of solid hard points. If I was going to build these myself, I would use 1/2 inch treated steel at the minimum with 6 ton shackles and either weld directly to the frame or use at least 4 rated bolts per bracket with about 25 - 30 square inches of direct contact with the frame.
