Leaf Spring Bumper stop advice

What color sumosprings did y’all install? Considering these to help towing.

 

Blue for me. I'm only doing light hauling with this light duty truck. If I buy a heavier slide-in camper some day I might need to upgrade, but the blues are plenty for me now. I have no idea how worn out my leaf springs are, since I have no idea how the truck was used most of its life, but I assume it's had pretty light use. All the same, 20+ year old leaf springs are probably a bit tired. Still, with my trailer attached, which I've assumed has about 300lb tongue weight, plus a ~150lb topper, my truck isn't squatting with the blue sumosprings.

 

Blue for me as well. With the permanent topper and 300 lbs of camping gear, it sits flat and rides like its on pillows over any type of road. We just did about 50 miles of maintained logging road, and I noted to myself how calm everything felt over washboard and exposed roadbed.
The rear springs are OG and sagged to the point that they are almost touching the tall Sumos, so any amount of compression involves the Sumos, and they kick in and act like a progressive helper spring. As an added benefit, the leaves won’t sag much more because they are not having to deal with the whole load anymore, buying some time before new leaves are inevitable.
