What have you done to your Tacoma today? 1st Gen Edition

Shear is actually highest at the load point (leaf spring and shackle hangers in this case), so reinforcement around those areas would be the best. You’ll want to avoid stress risers at the ends of the reinforcement so no vertical ends of the plates.

Boxing would definitely add another shear plane, and has the added benefit of increasing torsional rigidity of the frame rails as well. Gluing a plate to the open side of a channel isn’t as efficient as a milled rectangular tube, but seeing how far you have it stripped down that could be a good option for you.

Bending moment is highest at the midpoint of a span, so if you’re going to reinforce the flanges the high point of the frame arch would be the place to do it.

 

Okay that makes sense, I was always taught to sort of trapezoid or diamond my frame joints and assumed that went with plating too, I see why now. Not a lot of real estate at the shackle hangers to work with but I think I can whip something up. My main hangers are plenty reinforced I'd think given its now double wall and the hangers are set into the frame. I'll have questions when I get to dealing with the inside of the frame, have to get the shocks in first though.

 

How hard was this to install? It looks tight up by the the 1,3,5th gear locations.
Is this the same item here, the handle looks different,
Does it stick up, out higher?
Any issues with it popping out of 1st gear?

Any issues?

 

All this engineering talk and I just went at my shit like hur dur this looks strong.

 

I didn’t install the upper black part when I took the picture. Shifts smoothly no problems

 

For the most part I design by eye anyway haha, if it looks strong and feels strong it's typically okay. But feeling the frame all stripped down where you can move everything a lot by hand... makes you wonder where things should go not to hurt anything. I'm dealing with space constraints, otherwise it would probably be easier to just plate everything haha. But Dan raises a great point of how much you can stiffen it before tearing/cracking becomes the new issue.

 

I figured all the other companies that advertise fully boxed frames can't be wrong, right?

 

It's not hard to install just tight. I did have to have help to push down on the collar thing a ma jigger.
Mine has popped out of first like 2 or 3 times. But it could have been beacouse I had pressure on the stick.if you use the provided new upper stick the throw is actually the same length. Or it feels like it. but the stick is higher and there way more positive feeling.

 

I mean, 1st gen frames would never crack.


That being said, I actually don't think I have any behind the front suspension. A closer look is in order this spring.

 

Does the rear axle count?

 

No, not the frame.

 

1st gen frames are totally super strong, especially the rear

 

That's a hell of bend. That section is double wall on mine now... but I gotta ask, what did that cause I can't imagine it was just the drivetrain haha

 

Taking this line:

Had the winch stalled out pulling the front down, and I was flooring it in double low to get out, I was wedged in there pretty good.

 

Ah gotcha, bummer about the frame but looks like an awesome time was had either way. I'm sure you'll get it all fixed up, might even yank out most of the way

 

Heres how we fixed it and I drove it home:

That trail is my nemesis! I flopped on that same line when I was IFS. I am going to get some rear frame rails made from a local race frame shop, chop the ass end off and burn them in. 2x4 mandrel bent tube!!

 

That's the way to go.... I have regrets about not chopping my frame off and rebuilding it when I tore it down

 

I'll have less than 4ft of original frame when it's all said and done as I frame chopped the front of the truck when I did my SAS lol! I'm glad that didn't fail!!

 

So in your mofesional opinion, what would an ideal balance of reinforcement be for the rear frame?
I have both the outboard frame plate kit and the boxing kit from trail-fail.
Planning on doing the boxing kit, but that in addition to the outboard plate kit does seem a bit excessive. But idk, @Squeaky Penguin and a few others I've seen have that combo and haven't seem to have any failure on the rear of their frames from it being too stiff/rigid or anything
