Long Travel to already lifted truck

This is my first post. I've always read this forum to find answers to questions I've had along the way. This question is due to not finding any real answers besides "don't do it" which has never been a good enough answer for me. Please be nice, pretentiousness is really not welcomed. What I've done thus far is done and that can't change.

Question: what is the problem with adding a LT to a truck that has lower control arm drops?

My truck's lift history. I bought, I believe, a rough country 6in lift. At that time I bought the factoryish king coilovers. The kings are about two inches higher than stock so the 6" spacers in the kit wouldn't work. I ordered the 4" spacer to ultimately make 6". I later bought aftermarket upper control arms and rebuilt my king's to eliminate the need for the 4" spacer. Note: When I put the kit on I had to cut the crossmember (ultimate reason for my question).

The things I've read say the drop brackets can't take the strain of a lt. not sure why? And, the center of gravity would be off. To me, the center of gravity is dependent on how high you adjust the coilovers. I don't want to get more height. Honestly, lowering slightly would be fine. For that reason, I feel like if anything it would be better on CV axels and general angles of the IFS to have the drop brackets with the lowered front differential with a long travel sitting at say 4-5".

I have done all the work on this truck, I have mig and tig welders in my garage and I have a high mechanical aptitude. In my opinion anything is possible, I need real honest knowledgeable reasons for it being a no go.

It's a daily driver and I don't do anything real extreme. I mostly like to haul ass down dirt roads and empty wintertime Texas beaches.

Thank you for your help.

 

No pretenciousness from me just general offroad guy thoughts:

1. It can definitely be done but a few things you will run into:

2. LT is already hard on a stock tacoma. LT guys break shit all the time without the added stress of a DB lift. I hope your as mechanically inclined as you say because if you want to do high speed stuff (dirt roads and beaches like you said) it's gonna break. You will have to custom fab and weld gussets and supports etc. Especially around the DB itself and surrounding frame. Totally new territory and I wouldn't even know where to begin with that hopefully some fabricators chime in.

4. You will need new coilovers. standard 8" lt coilover won't work.

5. Yes lots of things are possible. For a 4x4 it's over 6k for LT, axles and coils. Being part of the off-road community for while and seeing thousands of different kinds of rigs IMO you would not be getting your money's worth out of the LT if you paired it with a DB lift.

And whatever else the wind decides to blow in your direction. I say this because there's gonna be tons of random shit you gonna run into and you will have to find solutions for.

But isn't that the fun part?

 

This guy is going from DB to LT.

I had the pleasure to come across an actual guy on the facebook TW group who had a 3.5 Camburg kit on his second gen after he already had a 6 inch lift on his. He couldn't figure out why he went through 5+ cv axles in a year...as others said its the taxing load that LT puts on these trucks. If you are mechanically inclined, then you would know that the longer your axle, the more torque and strain will be put on your mounts and the like. This is partly the reason why most guys who use their trucks to get airborne have to reinforce their whole frame as our frames are only so strong. With the added stresses that an LT kit does for just elongated arms and geo reasons, turns our truck frames into soda cans.

That being said, do you need the lift? If not, remove it and fab up a new crossmember since you seem to have the tools. As BrianT23 stated, you are trying to stack components that were never designed to be used together with different geo functions in mind. LT components are pretty stout to begin with, would hate to see you blow something up at speed that could lead to catastrophic results should your 6 inch lift give out at an unpredicted time.
