After about 60K, I switched over to Bilsteins on my F250 diesel. They did okay, but I cannot say they were the best thing since sliced bread. And they were very expensive, however.
At 115K miles, my tire dealer on an alignment said my shocks and a bad tie rod end resulted in my losing about 10K mileage on my tires.
I immediately went on RockAuto.com and bought the heaviest Monroe Shocks available at a ridiculously low price. And after installing them myself, I cannot tell the difference between Monroes and the Bilsteins.
My tire blew at night on I-285 bypass in Atlanta on a rainy night 2 weeks ago Changing that tire was pretty difficult for my daughter--under the conditions. I know now to not to wait until 115K for an alignment (even though it didn't need aligning), and to change shocks often. It's worth $60 to have a good suspension inspection every year on any vehicle used for towing.
