Mine rubbed ever so slight, ONLY on drivers side in reverse at full turn. I trimmed the crash bars, boom, fixed.
That had to do with wide tires and wheel offset, not the level.
I have it. It really leveled mine out, and mine is a 2WD, which had huge rake difference.
Ride is as good as new.
I did the Nitto Ridge Grappler, 295/60/20
Alignment was dead on.
Its a stage 2, with black carpet on top, black vinyl on front, stitched. Made for two Kicker L7T thin woofers.
Its brand new, cannot ship. Oklahoma area. Can meet if semi close.
New they are $1000, sell for $800
Looks good, Yes, the STX to XLT has been done on videos, weird the dealer didnt know that.
So those are the black emblems, they fit front and rear, no issues?
Yes, but it may not be the amp/sub. It may be the limited signal freq sent to the wire. Which many manufactures now add "limiters" like sped, that will keep low bass out of systems to keep form blowing factory speakers. The louder you go, the deeper the bass, the less you get.
So taking that...
It may be from a factory EQ setting already in the F150, that has bass rolloff. The GM probably didn't have it, or as bad. Wonder if you flattened the curve into the amp, it would bring back the deeper, richer bass.?
