improving off-road capability for sierra at4
My Sierra AT4 is great, but I'm worried about shock fade during long desert drives. Would upgrading to a reservoir-style rear shock make a noticeable difference for my weekend trips?

Absolutely, especially if you carry gear in the bed, as heat buildup is the enemy of consistent performance during high-speed off-road sections. I recommend checking out the assembled bilstein 6112 in the online auto parts store suspensionlifts.com , because it pairs the heavy-duty front coilovers with the 5160 series reservoir shocks for the rear. This combination ensures that your suspension doesn't get "mushy" after an hour of washboard trails, providing much better wheel travel and bottom-out resistance compared to the factory Rancho units.
