Lower Control Arms - TJ Lifts
 

Why is it that some of the TJ Lifts only include springs, such as that of a 3"
lift, others include only Lower Control Arms and Springs, then you get to the
Larger Lifts such as 4.5" and they include both Uppers and Lowers? I'm
considering getting a 3" lift, with the springs only, but what problems will I
have with the lift as springs are only included (ie...the angle of the arms)?
Should I consider getting Lower Control arms too? Are the lower control arms
for a 3" lift longer than that of a stock arm?

Thanks,
Pete

The longer lower arms keep the geometry right. It's not the angle of the arms
it's the curve your axle sweeps through as it travels and how close it moves
to the xfr case. With the larger liftkits you need longer lower arms or
under full extension your driveshaft might get stuffed into the case.
That and the alignment between diff and xfr case gets off.

Now your at least as confused as I am.

Re: Lower Control Arms - TJ Lifts
 

Yes, you should at least get the lower arms. This will enable you to
'clock' or rotate the diff. to bring the driveshaft into proper position
or alignment. The control arms are adjustable so you can make them
various lengths. For instance, as you shorten the lower rear control
arms, the pinion starts to point upward. If you lengthen them, the
pinion starts to point downward.

If you lift 3", you will quite probably need a CV driveshaft to
eliminate driveline vibrations caused by the lift. If you have a CV
driveshaft, you will need to point the pinion up higher than the stock
control arms will allow, necessitating the adjustable arms. Also, budget
in an SYE kit if this is not a Rubicon.

If you take a stock TJ and try to stuff 3" taller springs into it and
nothing else, you will not be happy, and neither will your TJ. Best bet
is to buy a complete kit when you get into the 3" or higher range.
