Are the Rubicon Express 3.5" standard lift kits(coil spring lifts) and the Rubicon Express 3.5" SuperFlex kits(short arms) same at the lift heights? Do the replacement control arms have something to do with lift heights, or they just providing more flexing ability when off roading? Thanks!

 

The coils should be the same. Most of these companies make the lift kits easily upgradeable, so if you want to go from the standard to the SuperFlex, you'd just need to buy the arms and mounts and such. With that said, the arms are for flex and on-road driving.

 

Thanks for the info

 

Yes the coils are the same in both kits. The arms give you control over the agnle of the pinion, better flex off-road, and are stronger arms.

 

Will the control arms in Superflex kit push the rear axle toward the back a llittle bit?

 

yes but not by much, since it only has upper adjustable control arms you cant really extend them to far with out throwing the pinion angle off. But moving the axle is not there purpose, they are there to adjust the pinion angle after a lift and when running aftermarket drivelines.
