oil is too thin, and springs are too stiff...go thicker oil, less stiff springs, and tell us what Tires/inserts you are using

Go up in piston size to 1.4 if you have them. I dont know the colors of the AE springs, but the lower the spring rate Number, the softer the spring, just go down 1 rate front and rear, go up in oil 5 weight in all 4 shocks, and see if you like that..you need to experiment with different things to see what you like, but start where I told you...there is no magic cure, you need to work at it..Good luck, have fun

I went softer on the springs front and rear.Also I didn't have 35wt so I went 40wt. in front and 30wt. in the back. We'll see if that helps any. Thanks for your help.

From my experience your on the right track anytime your truck seems bouncy you have to much spring and not enough dampening in the shocks to slow down the expansion of the springs.

To create more dampening you can do two things get thicker shock oil and change the pistons in the shock to have less holes or smaller holes.
Both of these slow down the rate at which the spring can simply put, spring
which will get rid of the bouncing.

in general if you make the springs stiffer you also have to stiffen the dampening in the shocks equally

30/25wt with 6x1.3 pistons is too light of an oil. Going to the 40/30 like you did will settle the car down noticeably. If the rear still feels like it's bouncing around a little, go to 35wt in the back. You shouldn't need to go any thicker than that though.

Hey, I was just wondering is changing the springs and oil wt. that I did is gonna affect the jumping and turning of the car. That wasn't bad before it was the bouncing that the car was doing that I didn't like.

It will handle better now. If it was bouncing before it will be more planted now, so you will get better traction and better stearing..You never want the car to bounce
