leveling kit... now bumpsteer.
2015 3.5eco, lariat, fx4.
ordered and installed the AutoSpring 2.5" leveling kit from Stage3.
Alignment done.
New tires: 295/65/20 Toyo ATII's
Drove from the installer to the tire dealer and noticed the ride was less plush than factory. Figured that was going to happen. Didn't expect the bumpsteer that has ensued. Its pretty bad.
Anyone else experiencing this with a leveling kit? I noticed it immediately with the factory tires, and even more so now with the larger/heavier tires.
Recommendations on fixing the issue? What remedies have you done?
TIA

You may want to look at page 229 in your manual. It talks about he adaptive steering. Might make sense to pull the battery cable so the adaptive steering goes through a re-learning cycle.

I have bump steer after leveling too. Bought some alignment cams to see if getting the alignment spot on will fix it. In my last two trucks going to wider tires made a big difference as well, so I am also thinking it could be from the wheel spacers I put on at the same time even though my tires are the same width as stock.

I'm actually surprised more people don't complain about this. If you look at the angles the leveling kits put the tie rods and ball joints at, it's no good. The fix for bump steer on lowered cars and race cars is usually taller tie rod ends or tie rod end spacers to get the tie rods back to their normal angle. I have no idea if anyone makes something like that for an F150.
While I agree that the trucks do look good leveled and that many people have done it with no issue, it's still not right. That's why mine is still at the stock height. I was really tempted to level mine, but know better. The properly engineered lift kits that maintain factory angles are a different story, I think those are a good idea.

I've always have lifted Jeeps as well. This IFS deal is very new to me and definitely a learning curve.

A 2.5 spacer can cause some harsh angles but I would guess it has more to do with the weight and size of the 295/65/20's. That is a lot more mass pushing back against the steering components. Sounds like overkill on just a level but a steering stabilizer would probably help.

Tire width plays a big part. I definitely experienced a little catwalk with the 305 65 18 KO's , a little with the 295 65 18 Duratracs, none with 285 GY Silent Armour or 275 Destination AT's (all with Bilstein 5100 leveling struts), and now, so far nothing with 285's and a 2" spacer for a level. Always on OEM wheels and no wheel spacers.
I also disconnected the power steering for the spacer install.
