Ok I have a Tera flex 2.5 inch coil lift and I want to go to 3.5.. So I I change my coils to 3.5 what all do I need to change?
Any advice would be appreciated

This is on a 2008 jk wrangler 2 door

 

Well I already have 2 1" spacers on the right side of my jeep bc it sags and I have no idea why!! Do the 1 inch spacers level it out so I do not know what to do ! Help me !

 

At 3.5" you might need a new front driveshaft if you are an automatic.

 

Yes I have one in the front and rear of the driver side and I don't know why !!

 

Did you extend bump stop?

If not, your coil got fatigue when your coil has compressed more than 70% of free coil length.
If you go to trail many time and did full articulation many time so your coil would sag within couple of years IMO.

I guess driver side coil is slightly longer or stiff than pax side normally due to occupied driver make it level hence when no occupant on drivers seat RH side would sag at full fuel tank

 

It happened with in a year and I called Tera flex and they said its normal and sent me 1" coil spacers for the right side ...

And no I did not extend bump stops ...

 

I added coil spacers all the way around with no real issues on a 2.5" teraflex kit. My front axle is a little bit off but no real problem aside from it pulling to one side. I am planning on switching to either rock krawler 3.5" coils or the evo plush ride 3" coils. I am going to be adding extended front brake lines front lower control arms, an adjustable front track bar, extended rear sway bar links, (I have the jks front disconnects so i wont need to replace them just extend them) longer shocks, and possibly a rear track bar and rear upper control arms if needed. My rear axle is still dead on with the 2.5" rear bracket from the teraflex kit but we will see when I change the springs.

 

We are discussing a similar issue in another thread..

My advice would be to find someone's JKU Rubi springs and shocks and replace yours with those. Thus eliminating whatever existing coil spring issue you may have as well as gaining some lift on your 2 DR JK. Gains are anywhere from 1-2" I think on average. I did this myself and gained over an inch AND improved the ride a bit because I still had 07 JK X factory springs and shocks.

There are a bunch of folks with 2012 JKU springs and shocks for sale and $100-$150 is a fair price.

 

The guy currently has a 2.5" lift and wants to go to 3.5". How would rubi springs get him there?

 

I forgt to say that I have jks disconnects and a rock Krawler frot track bar and I'm gonna order the rear soon also...
I might switch to the Evo plush 3" coils and if I do so should I change my Tera flex shocks ?
