4" short arm and 2" budget boost?????

Ok I had asked about this before and didn't get many answers. So here I go again. I had just installed a 4" full traction short arm lift on my jeep only to find out it had alredy had a 2" budget boost. Any way I left the spacers on so know it is 6" taller than stock. Will this cause any problems? I have adjustable upper control arms and am planning on a super short SYE anyway. will there be any clearance issues with articulation? I was told the steep angle of the control arms would cause a rough ride but the angle really doesnt look that steep. Any thoughts, sugestions, opinions or personal experiences would be greatly appreciated. Thanks in advance.

its up to you. does it work okay for what you want it to do? If you get crazy bumper steer you'll want to lengthen the lower front arms to correct the caster.

If you like it and it drives okay then leave it. If it were me I'd remove the spacers to get more droop and get back some of the wheelbase back that you lost from the spacers.

one more thing... i ran 3.5" coils and a 1" body lift for a long time and loved it. I ran that setup with 35s on stock control arms all around except the front lowers (the front lowers were adjustable to correct the caster angle).

if you like that height, then I'd recommend removing the spacers, installing a body lift and motor mount lift and you'd have a way smoother ride that works great on the trail.

Besides the rough ride steep arms cause, the bigger issue is they barely let the axle move or lift up when a tire is trying to climb up and over an obstacle. Instead of a horizontal control arm that helps the axle and tire to climb obstacles more easily, steep control arms force the the entire Jeep to raise up instead while climbing an obstacle which really adds a lot of strain and difficulty to the process.

Hold your arm fairly horizontal then push your fingertips up 5" while holding your elbow stationary. Easy right? That's how easy it is for a tire to climb an obstacle with nearly horizontal control arms. Now hold your arm so your hand is pointing down at a steep nearly vertical angle and push up on your fingertips again. You'll then see the problem as this last test tends to lift your entire arm and elbow.

6" is just way too tall for short control arms, I'd at least remove the 2" BB. Not just for ride comfort reasons but to help your TJ perform better offroad.
When you have a choice, buy American.
