Benchmark Designs dual battery tray support

I just finished installing dual battery's but to my dismay the kit supply's a solid strap to support the forward end of the tray down to the shock tower. Dumb!! as the body is rubber mounted to the frame. This mount will cause flexing of the tray or fire wall that it is bolted to, something is going to brake! I made a bracket to support the tray like the OEM. Also incorporates a mount for the emissions solenoid that they forgot. I am new to this site, so if I did this pos wrong maybe some one will set me straight. If I can help with drawings or complete bracket just email me [email protected]

I'd be interested in seeing the dimentions because I've got the benchmark kit on the way and I'll probably run into the same problem

so just curious did you call Benchmark with your concerns? My dealings with them have been nothing but positive and if you bring these issues to his attention he usually makes changes and makes it right with you... just sayin

That's a good looking bracket, but I think it would interfere with the mounting bracket for an AEV snorkel, which I assume you don't have. :-)

You are correct I do not have a snorkel, it is mounted to the original battery support hole plus an additional hole just forward of the original. I have only talked to john once when I ordered the dual battery kit and axle reinforcement tubes, it took about 4 weeks to get the battery kit and another 2 weeks for the tubes, no instructions with ether, Tried many times to talk to John, no answer and no returned call or email? Enough on that. The material is 11Ga. steel, I have attached the cutting drawing and the bending drawing in pdf format.
I have some extra metal left over and could mfg. a bracket or two if some one wanted me to.

Thanks for the drawings. I'll wait for the kit before I move forward with it.

Looks really good.

Nice job on the bracket. I'll have to see if I can make a rough version of it. I like the idea of being able to mount everything from up top, and having some place to mount the emissions solenoid.
My only question would be, if your capable of doing that, why would you order a prefab battery tray at all?

I Guess I am basically lazy, and it was easier to buy Johns than to reinvent the wheel. It is a good design except for the brace that attaches to the shock tower.
Just thought it needed a little help after I got into the install.

Hose splice

I was just wondering what type and size of hose you used to splice the rigid plastic line going to the emissions canister.
Is it under pressure, or will any rubber line work?
I find it just too hard to try and get it to bend without kinking.
Thanks

Just completed dual battery tray install

At last, and after more hours than I will admit, I finished the dual battery install. In addition to the install as outlined in the Benchmark instructions, I put in an 'L' shaped bracket which I sandwiched between the two Benchmark tray pieces to work as an evap purge solenoid bracket. I had to lengthen the electrical wires and replace parts of the rigid tubing with flexible rubber tubing to suit. Also I put a fuse block attached to the battery tie down bar. All the aftermarket mods go through this fuse bank. I also wired the relay to 'keyed' power from the lighter. The winch and the 'buddy boost' are connected directly to the aux battery. Photos show what it looks like. I have a compressor coming next week and it will be wired off the next fuse. There is quite a traffic jam of wires arround the batteries but I'm basically pleased with how it turned out.
