I installed Monroe 58427 SensaTrac overload (or "load leveling") shocks on my car.

They provide a nice ride quality and prevent the car from sagging too much with a heavy load.

NOTE: After about 18 months, these shocks were incredibly noisy. I replaced them with conventional shocks, along with stiffer CC667 springs. The new springs, having a variable rate, provides better ride quality than the OE springs combined with these shock absorbers. The load carrying capability of the car is comparable.

Comparison of old and new shocks
The old shocks were well worn; it took about 5 lb of force to compress them! The new ones are incompressible with human arm strength.

The right side shock was difficult to remove. I had to cut it off the axle and the mount.
