Definitely a big difference in the ride quality and handling with a Long Arm.

 

what's the differences between the 3'' and the 4" long arm kits? just the springs?

 

I agree. I went from stock, to a teraflex leveling kit, to my Teraflex 3" LCG long arm lift. SUBSTANTIAL increase in ride quality. Much beter than stock IMO. Tracks better on the highway, flexes easier and better, and it rides soft, even with 35lbs of air in the 35" tires I run. Def glad I went longarm. I see lots of ppl going with a full flex arm lift, only to upgrade to coil overs in the future. I won't have to worry with that. All I need is taller springs if I wish to go bigger.

 

Yes just the springs

 

Coils, shocks, trackbar brackets, drop pitman arm, longer bump stops

 

well yes you are indeed right. After 4 inches do a Drag Link Flip Kit. Shocks yes. Bump stops ...... Iam thinking they are the same for the 4 and 6 inch kit. Could be wrong.
Its ok my next step is coilover and evo-lever.

 

Some 4" kits like the teraflex come with rear stainless steel braided brake lines instead of the drop down brackets. My 3" came with the brackets, and they are barely long enough. I'm buying longer lines.
