The hard part with shocks on these heavy duty trucks is that most people don't notice what they do because of the heavy suspension components. That's why so many people are running around on shocks that no longer do their job. I'd be willing to bet that 75% or more of the trucks on the road have collapsed shocks. My experience and recommendations with shocks is simply this, Monroe shocks last about as long as OE, maybe 20-30k miles. Rancho shocks look nice, but don't last much longer, maybe 40k. Bilstein shocks have lasted me nearly 100k miles. The problem is most people don't pull shocks on a regular basis to check their dampening ability.
