Radflo’s 3.0 Series Bypass Shock with Piggyback Reservoir and 4 Tubes combines position sensitive external bypass tuning with velocity sensitive internal valving, delivering true dual-stage performance in a single shock package.

Softer damping during initial travel maintains comfort and traction, while firmer damping near the end of stroke resists harsh bottom-outs at speed. The 4-tube external bypass system allows precise adjustment of compression, rebound, and bleed characteristics at specific points in the travel, giving you race level control over how the suspension reacts in real terrain.

At the core is Radflo’s exclusive Freeflo® Racing Piston, which uses adaptive damping technology to automatically match shock performance to surface conditions. Combined with a 1 Nitro Steel® shaft, CNC machined bronze rod guide, and a multi-direction sealing system, this shock is engineered to survive extreme abuse while remaining fully serviceable and tunable.

Includes:

  • Radflo 3.0 Bypass Shock with Piggyback Reservoir
  • 4 External Bypass Tubes
  • Universal spherical bearings and mounting hardware

Availability Note: As the #1 Stocking Warehouse for Radflo, we maintain the largest on-shelf inventory of shocks in the industry. While we keep the most popular lengths ready for immediate shipment, the high demand for specialized sizes can occasionally result in a lead time on shocks that get ordered. 

We are committed to getting your rig on the trail as fast as possible. If your build schedule is critical, please call us to confirm real-time inventory before placing your order.

Tech Insight

Bypass shocks are the gold standard in off-road suspension because they blend position-sensitive damping (external bypass tubes) with velocity-sensitive damping (internal valving). The result is unmatched control across slow crawling, high-speed desert, and hard impacts—all without compromise.

Radflo’s Freeflo® piston adapts instantly to changing terrain, while externally adjustable bypass tubes let you fine-tune compression and rebound zones in seconds. Radflo shocks are completely rebuildable, with every internal component designed to be serviced or re-valved—either by Radflo’s technicians or in-house by experienced builders. This makes the 3.0 Bypass ideal for builders and racers who demand precision, consistency, and long-term serviceability.
