Just picked up from the shop.
2008 Z71 Suburban
Rough Country 7.5"
Eagle Alloy Series 050 20" (Made in MURICA)
35x12.50x20 Nitto Trail Grappler Mud Terrains
Great install by my usual shop. However truck is nearly non-drivable at anything above 50. Floats so badly, and is impossible to drive in a straight line. Constant corrections on the steering wheel, and was positive I was going to be stopped by a Trooper for DUI since I was all over the lane.
I've ordered ProComp rear lower control arm drop brackets to try to get the rear lower arms at a better angle, and push the rear axle back, but the correct solution to that will likely be longer upper and lower rear control arms.
Wheel spacers arrive today to try to get the front and rear wheels in line which may help with tracking.
However, I believe the issue is simply going to be front OEM suspension parts that are worn (130K miles) that weren't an issue before, but are now due to the lift.
Lift shop did alignment, specs are spot on, GM master tech friend looked at my alignment sheet and said it is perfect.
Anyone have recommendations on where to start tackling this issue, whether with aftermarket parts or what OEM front end suspension parts? I can only drive this thing to the grocery store and gym, since speed limit is 45MPH between home and there.
EDIT:
Added this photo, you can see the horrible rear axle position from the lift kit. Why they don't include the necessary control arms or brackets to extend stock arms is beyond me. I guess they wanted to make a cost effective kit that comes in below the competitors, which is fine because the kit is otherwise very good quality, but to me this is no different than a car dealership taking off the wheels of a car to undercut another dealer's price. Sure, it is cheaper, but the product being sold is now undrivable. I would rather have paid more and have a ready-to-roll vehicle.
The rear tires are pushed up against the plastic surrounding the Z71 specific running boards.
