spacer blocks with road bounce.

I've looked up and down the pages hoping for an answer so I don't have to ask the question about spacer blocks. LOL, I'm that guy in the back of the class.
So, I got a 17 sport with 6k miles on it for a great price. it has 3/2 spacer blocks 20" wheels and 33" tires or whatever the metric measurement is. I don't do any off roading other than a farm road. I carry my dirt bikes and that's about the most stress this truck will see.
The truck rides amazingly smooth, My wife even thinks it rides better than my limited. my problem is on the freeway if hit a dip in the road the truck kind of lets the road dictate where I'm going at times.
My question is, is this normal with a 3/2 spacer lift 20" wheels and 33" tires?
Or should I think about putting on new UCA's Ill let the pros take over from here.

It’s probably not the spacers that cause that, it’s more than lightly the front alignment. If it was a fixed front axle truck, then absolutely it would be the lift. The wheel offset and small sidewall profile those tires have, can also have an effect.

 

I would get alignment checked. Your caster might be at a low under + 1 degree with stock control arms with that lift. Alignment shop may not of max'd caster out as with stock control arms, you may get close to + 1.5 with stock.

 

Bounce? You may need shocks...it’s what keeps the tire in contact with the road

 

no not really a bounce. more of going down the road relaxed and then the truck hits a dip or weird spot on the road and i find my self-needing to take over the wheel again.

 

Sounds like what the truck is doing is normal...keep in mind it’s no longer stock. Larger wheels and lift changes the center of gravity among other things with 4600 plus pounds...it’s gonna be a handful over stock on the dips and weird spots. You can play around with tire pressure it may ease the need to take over the wheel...

 

thanks. so do you think with this lift i cam skip the uca, i plan to drop to a 18rim. i dont like the 20

 

If tire wear is even and the truck tracks straight down the road at highway speeds...I would skip UCAs. Set the truck up the way you plan to use it and looks to personal tastes

 

It's called bumpsteer.
Tie rod angle is pushing/pulling tires as suspension cycles.
Normal for big lift, big tires, high offset wheel...
UCAs and alignment won't do jack.

 

Thanks, Thats why I asked you guys. !

 

3" up front, as far as changing angles of suspension, CV and steering components? Yes.

My personal limit is 1.5"; 2.5" is pushing it. Anything more than 2.5", your're better off with a drop bracket lift with new spindles.
