Ive pondered raising my engine 2 inches for more uptravel, lower stance, and flatter belly. Truck has body lift and lots of tubing im not redoing and im trying to make the most of it. your thoughts please.

Cog...

huh?

Center Of Gravity... it goes up when you raise your powertrain. Vehicle won't be as stable on sidehills, quick turns... whatever.

But, if you can raise your motor/trans/tcase and then lower the entire rig with your new found clearance, then you've got the best of both worlds!

Yup.


If you very carefully lay out your engine/radiator/front axle/steering ram, you might be able to make it all stuff together. I can't, and ended up going with a bit taller springs. Bottom of your engine could be nearly flat with the bottom of your framerails, and you could run a lower arched spring. Wouldn't be worth it with IFS framerails (they'd be lower than the engine, and you'd further lose uptravel), but would with stock SA or 2wd framerails.

Do spend the time trying to lay all the pieces so they "mesh", though!!

body lift? i assume you dont have an ftoy?

confused

Yes, my plan is to raise the upper shock mounts to lower the truck. its an 86 frame, with 3 link front, 4 link rear, with 16" race runner air shocks. I only posted on f toy forum cause I had read about lowering engines on here and wanted some technical advice from guys that are bustin ass with theirs.

My advice makes sense if you're moving your engine back. If not, you'd be mostly concerned with oil pan clearance.

With a body lift and an engine lift, what you're really accomplishing is a "frame drop". Is that what your goal is?

raising your motor and then running flatter springs doesnt cancel each other out. you are still raising your motor higher than your spring mount. so on a side hill, it will have more leverage to unload and roll over no matter what spring you are running.

my main goal is to make the most of the body lift, since its somewhat unreversible because of all the tubework. Raising the engine will allow me 2 more inches of uptravel, therefore raising the upper shock mounts, trying to go low as possible. The upper link mount is contacting the oil pan.

i don't know what your current travel is, but 2" of up travel in a ftoy can make all the difference.

like you said, you need sound advice for what you currently have, not rebuilding from scracth. sounds like a motor lift is what you need for your buggy and your purpose.

different oil pan?

I think it sounds logical that the weight of the frame being lowered would help a little bit. As far as raising the center of gravity and then lowering it, this truck/ftoy is obviously held up by something more than leaf springs. Would the slung weight of the frame being lowered actually lower the COG by a hair? I think it would be enough to make a difference...

edit:
This is a thread about the cons...

I am too focused on the cool factor of lowering the frame.
