My f150 xl 4×2 has full time Are utility tool topper in bed! About 700lbs always! Also tow 7×16 travel trailer often. Before adding sumo’s the stock bump stops with trailer tongue weight sat about 2” above axle! Traveling with the 2” was a little less than ideal, now with the 1” spacer provided with springs installed, big difference in how this set up performs, springs set on axle maybe 20-25% compressed and makes me feel much more in command, no more sway or uneasy 😳 towing experience. Haven’t driven truck without trailer attached, so can’t speak to stock ride, really won’t matter for this is a dedicated tow rig! Without trailer attached, sumos basically just brush top of axle! I imagine, it probably will ride different than stock, won’t be a problem. Thanks- SuperSprings/ Sumos 👍
