The Radflo 3.0 3-Tube Bypass Shock is engineered for maximum damping control in the most demanding off-road racing environments. Featuring a massive 3.0 body and a 1 Nitro Steel shaft, this bypass shock delivers extreme strength, superior heat management, and elite level adjustability.

Bypass shocks blend velocity sensitive internal valving with position sensitive external adjustment, creating dual-shock performance in a single package. Softer initial travel absorbs chatter and small bumps, while firmer damping in the final stroke resists harsh bottoming on big hits.

Three external bypass tubes allow precise tuning of compression, rebound, and bleed resistance across specific travel zones. Adjustments can be made quickly, giving racers and builders total control over suspension behavior.

Includes:

• (1) Radflo 3.0 3-Tube Bypass Shock
• Remote Reservoir
• Universal Spherical Bearing & Mounting Hardware

*Sold Individually

**Springs Sold Separately.

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

The 3.0 body significantly increases oil volume and heat capacity, making it ideal for high-speed desert racing and endurance events where thermal control is critical. The remote reservoir further enhances consistency by separating nitrogen from oil and reducing cavitation under extreme use.

With three external bypass tubes, you can precisely shape the damping curve throughout the shock stroke controlling small bump compliance, mid-stroke stability, and bottom-out resistance independently. Combined with Radflos Freeflo Racing Piston and velocity-sensitive valving, this shock automatically adapts to terrain while allowing external fine-tuning.

Fully rebuildable and tunable, the Radflo 3.0 Bypass Shock is built for racers and serious off-road enthusiasts who demand maximum control and reliability.
