Debating on dropping my lift down from 4" to 3" for a few different reasons. What parts would it take to change over (drop) my 4" Teraflex Full-Flex Arm kit to a 3" other than the new coils? Seems lots of the Teraflex parts change from 0"-3" and 4"-6".

What I'm currently running:
TeraFlex JK 4-DR 4" Suspension System w/Full FlexArm System w/Shocks (1451400)
With TeraFlex JK HD Frame Brace and Drag Link Flip Kit (1600440)

What I'm debating switching to:
TeraFlex JK 4-DR 3" Suspension System w/Full FlexArm System & Shocks (1451300)

I obviously don't need to rebuy the 3" kit as I already have 90% of the parts, but I know the 4" kit included parts the 3" did not such as:
-Extended Rear Brake Lines
-Rear Upper Bumpstop Extensions
-Front Lower Bumpstop Extensions
-Front Monster Fordged Trackbar (keeping)

In addition to the four coil springs, do I need to change:
-to shorter front/rear swaybar links (from PN:753000 (4"-6") to PN: 753010 (0"-3"))
-rear axle trackbar bracket (</= 3")? (PN: 1954777) <-- (FOUND OUT THIS IS GOOD FOR 2"-6" LIFT)
-front/rear brake lines (</= 3")?
-remove extra rear upper/front lower bumpstops?
-remove TeraFlex JK HD Frame Brace and Drag Link Flip Kit (1600440) (Description advises use with kit +4"--it's welded on).

Not happy with the wheel gap with my 35s (not going up to 37s), have a 5'2" girlfriend, and main reason is to go back to my stock driveshafts (need to drive highway routinely, get DS vibes at 65+).

Trying to figure out if it's worth the cost to drop down.

 

I asked Joe this via PM earlier this week. Here was his reply,

 

Thanks brother, seems like the easy enough answer but I'd be worried about the swaybar links. Can't see how they wouldn't have to be changed out also, especially with removing the upper/lower bumpstops, they'd hit the frame before the upward travel of the axle was stopped by the bumpstops.

Has to be more to it than that...wish I had a part number list for the 3" kit.

 

Why not spend the money on some heavy bumpers and gear to weigh it down a bit?

 

Already on...rig is built

 

3" kit uses 10" and 12.25" swaybar links and so doe's the 4" kit.

 

Thanks Joe, any issue with keeping the drag link flip with a 3" lift?

 

I'm interested in this answer also!

 

Me too. I have the 4" lift with 37's. I could probably lose like 2" of lift and still have no rubbing (and I still have stock fenders).

 

TeraFlex has install the original version of the #1600440 flipdrag link on a JK with a TeraFlex 3" system, worked great. Newer versions of this kit now have 2 mounting locations for the trackbar.
