No stiff-as-isht TTB coils here...
This is a Skyjacker 6" Cherokee (XJ) coil spring #JC60F shown next to a Rancho 3" Cherokee spring.
The Rancho springs sagged out over time, and were replaced with the Skyjacker springs.
Skyjacker's springs are much better quality, they've stayed at their original height with over two years hard use now.

Edit, lets make that seven years hard use now.
Skyjacker really does make a quality product.
