This allows the suspension to remain supple over small chatter, roots, rocks, and bumps while increasing damping force deeper into the travel for superior control during larger impacts.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eUnlike traditional coilovers that force all fluid through the piston throughout the entire stroke, DRT shocks utilize internal circuits that allow fluid to bypass the piston in specific travel zones. The result is increased small-bump compliance, improved traction, enhanced ride comfort, and a noticeably more controlled suspension feel across varying terrain.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eCombined with a remote reservoir and available dual high-speed and low-speed compression adjusters, the DRT Internal
