Have 2015 JKU with 2.5 inch lift. Teraflex lift is great, however, started to look into improvements to ride and handling and came across Fox shocks and control arm upgrade. Ordered a 3 inch tearflex S/t3 kit with Fox shocks that includes new springs. Thinking I am going to change the hardware, but undecided in terms of spring replacement. I am completely content with 2.5 inch lift. I don't think I will ever go beyond 35 inch tires. Currently running 33s with great fuel economy. What are your thoughts on 1/2 inch lift increase. If there are pros/cons, please post them here.

Thanx!

 

no reason to go higher if 35s are your end goal. 2.5 is plenty

 

I have always considered the differences between a 2.5in and 3in lift was all in the name and nothing more. As some examples most that have gotten the AEV 2.5in lift have reported a lift increase of 3.5 to 4.0 inches. I recently decided to get the Mopar 2in lift and everything I read previously was that I needed at least a 2.5in lift kit to fit 35's, so I totally ignored looking at the Mopar 2in lift. Then after I did some research on the Mopar 2in lift, everyone who installed it was reporting 3 inches of lift and were fitting 35's with no problems.

I think the problem is that there is no real standard of how each lift is measured. So some take measurements without any other weight added to the vehicle which provides a Max lift amount. Then others provide a measurement with heavy items such as bumpers and winches already added and the measurement becomes more of a Minimum guaranteed lift amount.

 

Thanks, and I agree it will probably be unnoticeable. I guess the question is, since I have suspension components apart, should I just go ahead and replace 1 year old springs with brand new ones? Eventually I may throw more weight on it (bumpers, etc)

 

You could open up a hole new can of worms by lifting your Jeep more.

By that I mean you could then be dealing with axle pinion angles and caster settings for the front. Also you might have issues with the stock drive shaft boots tearing. So if you are happy with the way it sits now and don't plan on larger tires leave it alone 😎

 

Just me but I would go ahead and change the springs to match the shock replacement. Before doing the change and since both sets of springs are TF, I would check to see if the part numbers of the springs are actually different. Technically, they should be different but I'm struggling to understand the reason why TF would design/develop/produce a different 2.5" set and 3" set of front and rear springs. Seems kind of silly, so I'm kind of suspecting they may actually be the same springs.

 

Before you do anything what type of wheeling do you do and how much or is this more for looks than function?

 

The arms are fixed on the s/t3 kit made for a 3" lift. Best bet is change it all

 

Best advice yet.

 

I was thinking along those lines too.. Good point on comparing part number. I will also measure before and after height. The sport arms are fixed, however, according to teraflex sport arms will work with both spring set ups.
