I installed Monroe® Sensa-Trac®: Load Matching Shocks on my 2001 S-10 to haul 1 cubic yard of dry dirt or mulch and they did well for that purpose is working . They also made the ride very stiff, so I switched to these Monroe 32186 shocks for a 2,000 mile round trip with about 600 pounds max load and 350 pounds passenger weight. The 32186 improved ride comfort even more than expected with no load and light loads were not a problem. I'm very happy with them at this time.
