Monday through Friday it's a gooseneck, a bed full of material, and a job site road nobody grades. Saturday it's the toy hauler to the desert or the camper up a forest road. The factory shocks were picked to ride well on an empty truck at a dealer test drive, and that isn't how yours spends its life. With weight on the hitch, the heavy front axle starts to porpoise over expansion joints and the rear keeps moving after the bump is gone. On a washboard road the shocks heat up and fade right when you need them most.\u003c\/p\u003e\n\u003cp\u003eThe 8100 ZoneControl R is built for that work. Each corner gets a 2.65\" monotube with a 60mm piston and a remote reservoir, so there's more oil to soak up heat and more piston area to control a heavy axle. ZoneControl R adds a second rebound piston near full extension that catches the axle before it tops out, so one bump stays one bump. The truck settles faster, tracks straighter with a trailer behind it, and stays composed on dirt when it's loaded down.\u003c\/p\u003e\n\u003ch3\u003eWhat the Letters Mean\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8100 ZoneControl R.\u003c\/strong\u003e 2.65\" monotube with a remote reservoir and a second rebound stage near full extension.
