BTW, moving the shroud is much easier than the MML.
Can confirm this, was absolute headache.
But I wanted it for later on down the line when I tuck it (years, but still) and gives me a little more wiggle room to lift with out dropping the skid. I was safe at 2" before I added the motor mount lift, so I'll be able to get up to 3ish in the front, maaaybe the rear, too. IT does effect the driveline angle, but in a positive way. By lifting the motor the tail of the t-case gets tipped downward.
Overall depends on your plans OP
Poverty/College Budget 2004 TJ BB, 1.25" BL, MML, JK shocks, 313x12.5 Federal MT's
If it can't be fixed with squats or fish oil...your probably gonna die (u aware?)
General consensus is that 3" of spring lift is about when vibrations begin. Its a fuzzy borderline because each jeep is a little different.
The MML is really quite easy. I installed mine with the BL and it only added about 2 hours to the day. The part people seem to have trouble with is forgetting to remove the driver's side mount from the block in order to pull out the bolt. Lots of socket extensions helps a lot, too. I did the entire BL/MML install myself in about 5-6 hours.
Thanks for the replies but I have one question how tall of a lift can u go befor having to change drive line and steering stem etc.
Depends on what you're lifting. The only things a modest body lift (1"-1.25") effects in the drive train are the fan shroud, tcase linkage, shifter to console clearance, and fuel tank filler hose. With adjusting the shroud and using the tcase linkage drop bracket that comes with the BL the rest will be fine. If it's in you're budget I highly recommend the Novack cable tcase shifter. It works much better than the stock mechanical linkage. Once installed, the tub/tcase relationship can change whenever required and the cable doesn't care, same great shifting.
As for steering, even with a 1" BL I recommend a 1" steering shaft bearing bracket rise. Look at the upper intermediate steering shaft on a TJ with a BL, particularly the ujoint and rotating grommet at the firewall. They are at pretty extreme angles. We just replaced the upper and lower steering shafts on my son's TJ. They cost $340. The 1" raised bracket is about $40 from M.O.R.E. Or you can modify your own for free like we did.
That's my son's. I will be modifying mine when I install my JKS 1.25" BL this weekend.
I did the 1.25 zone body lift and MM lift it was pretty easy, came with a transfer case linkage drop and a steering lift and all the body mount stuff. MM lift was pretty easy also. Just remember to unbolt shroud before you start and gas tank hose by the cap.
