Combining velocity-sensitive internal valving with position-sensitive external bypass control, this shock allows damping to change throughout the suspension travel for better control over small terrain, large impacts, whoops, jumps, and bottom-out events.\u003c\/p\u003e\n\u003cp\u003eAvailable in 14\" and 16\" travel, the 3.0\" shock body, five external 3\/4\" bypass tubes, piggyback reservoir, and 1\" shaft make this a strong choice for Ultra4 cars, rock bouncers, desert race vehicles, high-speed trail buggies, and other competition-level builds.

What does a 5-tube bypass shock do?\u003c\/h3\u003e\n\u003cp\u003eThe external bypass tubes allow oil to bypass the main piston at specific points in the shock travel.

Why choose a 3.0 bypass shock?\u003c\/h3\u003e\n\u003cp\u003eThe larger 3.0\" body provides increased fluid volume and thermal capacity for demanding applications where shocks experience repeated high-speed cycling and heat buildup.\u003c\/p\u003e\n\u003ch3\u003e4. What does the piggyback reservoir do?\u003c\/h3\u003e\n\u003cp\u003eThe piggyback reservoir increases fluid and nitrogen capacity while keeping the reservoir directly attached to the shock. This eliminates the remote reservoir hose and creates a compact, serviceable package when chassis clearance allows.\u003c\/p\u003e\n\u003ch3\u003e5. Are these shocks custom valved?\u003c\/h3\u003e\n\u003cp\u003eYes. Radflo bypass shocks can be tuned for the vehicle's weight, suspension geometry, driving style, and intended terrain.
