Results of Bilstein/Rancho comparason
Well, the comparason was done this weekend on my newly installed set of Bilstiens. The test was made on a strech of Interstate 5 between Orange County and San Diego. As reported in Trailer Life Magazine recently, the I/S 5 is rated by long haul truckers as one of the top 5 worst in the country. The test was about 350 miles, towing the same RV I towed with a set of Ranchos on a 97' 3500 for about 2 years. 26' long, about #9000 pounds loaded, and #500 to #600 pounds of tonge weight.
While the Ranchos were a BIG improvement over the stock shocks, and the adjustability was a factor, the Bilsteins on this trip were amazing. While a truck is still going to ride like a truck, the big difference was that the Bilsteins controlled the upward movement better than the Ranchos. On a washboard surface like a lot of I/S 5 is, the "porpoiseing" effect that occurs with the truck and the trailer going different directions can be a gut buster. My wife made the most notable observation. With the Ranchos, she would have to "support" her upper chest on some parts of the freeway, for her own comfort. This was not the case with the Bilsteins.
This is appearently due to the nitrogen gas cylinder inside the normal fluid filled cylinder that smooths out the upward travel, and controls the rebound of the next bump. All in all, they are both very good products, and much better than stock. But if your about to upgrade, give the Bilsteins a hard look.
