Title: TJ 6" Lift Kit
Post by: Impact on May 14, 2009, 09:32:58 AM
Has anybody seen anyone running this Rusty's 6" TJ Kit at all?
I know there is alot of hate out there for Rusty's but I never had
a problem with my XJ kit from them. Any opinions on the actual
kit? Price is better then most 6" long arm kits.....

Probably a waste of my time, but here it goes.

The LCA brackets look weak, and have extremely poor clearence.

The front is a radius arm, and there is no excuses to be putting radius arms on TJ's in 2009. Radius arm geometry leads to unloading, and terrible anti diving characteristics. Specially on SWB wranglers. Longer wheelbase rigs can get away with it to an extent.

The lack of seperation for the upper and lower rear links makes for terrible rear suspension geometry. It will climb like a spring over yota.

The bushings combined with low misalignment cartridge joints will lead to frequent bushing failure.

The belly skid hangs way to low.

6 inch of suspension lift is to much on any SWB wrangler.

All the arms are to long and poorly located.


I would rate this suspension as mall crawler only. You couldnt pay me to run that pile of junk.

Thanks for your input. If I didnt ask, I wouldnt know.
About the lack of seperation in the rears arms, can you explain that a little more
to me for my own personal info lol.
About the radius arm setup, arent there other companies selling the same setup? (Which
I agree with what you said)
Whats the difference mechanically between running a stock control arm set up
compared to a tri-link setup?
Thanks
