So most know I was rear ended a few weeks back and parked it so I can start on repairs. I fixed most of the front end already and just had an adjuster look the jeep over for rear damage. After that I was going to take it home filled it with fuel for the first time since the accident and now the fuel tank is leaking... So I want to know what would you do if you were in my situation... Do I find another stock tank and just replace it or would you get something like the GenRight crawler tank? I do like the GR because you can stretch the WB and its aluminum. Anyone have a bad experience with the tank?

Check your fuel pump.

When my wife rear ended me my Jeep wouldn't start...

The impact broke the plastic pipe inside the fuel pump assembly. Everything was working but just not going down the line.

I did a lot of research on stretching with the GR 19 gallon stretch tank and was unable to reconcile too many issues with the amount of actual stretch, the amount of reinvention of the tank mounting with a proper frame stretch, how to fit the filler neck around my shock outboard and how to snake the exhaust out the back.

The aluminum skid was an automatic no, because it is fabricated incorrectly for the material, indicating that GenRight is not using 6061t6 aluminum. I have witnessed first hand how things like their bumpers made of 5000 series aluminum tear apart on rocks.

Go with a stock tank and a thicker late TJ factory skid. Then cut and raise the skid an inch.
 
Thanks for the feedback everyone...

@Nick21 Eventually this TJ will become a trail only rig down the line so I do see a stretch in the future...

@macleanflood Fuel pump seems ok as it drives just like before but now when full it leaked

@P man @jjvw What are they using for aluminum? My stock tank has a Kilby gas tank skid currently

If theres another tank that offers a stretch I would look in it. I wouldnt mind the clearance for when I get on some JL axles or even tons

Based on the bends on the GR skid, they are using a more malleable 5000 series aluminum like they do on their aluminum bumpers.

If you search, you will find a lot of discussion about the required minimum bend radius for 6061t6 aluminum to prevent cracking during fabrication and how the Savvy TJ product line is based around the characteristics of the material. With this understanding, one can begin to make informed determinations of what material is used based on the details of the fabrication. The bottom line is that GR aluminum products frequently have too sharp of bends for it to be 6061t6.

If I were dead set on a GR tank, I would only use the steel skid version.

Which I haven’t seen many of… 🤔


Either people aren’t using them too hard, or they’re wary of shitting on something they spent a grand on.

One thing I am fairly certain of is that a lot of people are not achieving the amount of rear stretch they are claiming to with some of these tanks. And there is a lot being ignored and glossed over concerning the rear suspension designs, especially where separate coils and shocks are being used.

Geometry and arm length affects the wheelbase change as the axle moves up and down. The flatter and or longer the arms are at ride height, the less the axle pushes back as it goes full stuff. Once the axle side is higher than the frame side, the wheelbase gets shorter.

Ok. Yes.

Meaning that when you define the rear axle position around the gas tank as a boundary, one needs to bring the axle up to full shock compression in order to identify how the diff cover interacts with the gas tank.

When one does this, the arm length and angle is irrelevant because the axle location at that position is what it is.

@jjvw Have you been out and see a GR failure in person? Do you personal experience with a failure?

I have seen a GenRight aluminum bumper fail when dragged through the rocks where nothing else in our Jeep little circle would have failed. It was made the same way as the GenRight aluminum gas tank skid plate. Neither are fabricated in such a way that would allow 6061t6. We drag our TJs through rocks.

That is all I need to know about the GenRight aluminum gas tank skids used for their stretch tanks. I know this for the reasons I laid out earlier.

What about GR aluminum sliders? 🤣

Bling bling…

I had every opportunity to make our own mini boatside out of aluminum. For a moment, early on, they were. The design led to them being steel. 😉

If anyone did have a bad experience it would be anecdotal. All we can do is look at and understand the design and materials used for that design to see if they are appropriate for the application.
