      Radflo DRT (Dynamic Ride Technology) Internal Bypass Shocks combine the comfort of a traditional coilover with the control of an external bypass shock in a compact package. Designed for rock crawlers, rock bouncers, Ultra4 race cars, prerunners, trail rigs, and high-performance off-road vehicles, DRT shocks use Radflo's proprietary internal bypass technology to provide position-sensitive damping throughout the suspension travel.

      Unlike conventional coilovers that rely solely on piston valving, DRT shocks incorporate internal bypass zones that allow the suspension to remain compliant over small bumps while progressively increasing damping force near bottom-out and top-out events. The result is improved ride quality, greater suspension control, increased stability, and enhanced confidence in demanding terrain.

      Available in both 2.5-inch and 3.0-inch shock body sizes, Radflo DRT shocks can be configured with piggyback or remote reservoirs and are offered with single or dual compression adjusters to match your vehicle, driving style, and performance goals. Whether you're building a competition Ultra4 car, a high-speed trail rig, or a dedicated rock crawler, Radflo DRT shocks deliver race-proven suspension performance without the complexity of traditional external bypass systems.
