The Radflo 3.0 4-Tube Bypass Shock with Piggyback Reservoir is designed for builders who demand the highest level of suspension control available. Built around a massive 3.0" shock body, heavy-duty 1" shaft, four externally adjustable bypass tubes, and an integrated piggyback reservoir, this shock is engineered for rock bouncers, Ultra4 race cars, desert race vehicles, competition crawlers, and high-horsepower off-road builds.
When suspension travel increases, tire sizes grow, and horsepower climbs, maintaining control becomes increasingly difficult. The Radflo 3.0 4-Tube Bypass Shock provides exceptional damping capacity and tuning flexibility, allowing builders to fine-tune suspension performance throughout the entire stroke.
The four external bypass tubes create multiple damping zones that help manage chassis movement, improve traction, reduce bottoming, and maintain stability during aggressive driving. Combined with the increased oil volume, the Radflo 3.0 4-Tube Bypass Shock delivers the suspension control serious drivers expect.

Tech Insight
1. What is the difference between a 3-tube and 4-tube bypass shock?
A 4-tube bypass shock provides additional tuning zones throughout the suspension stroke, giving tuners more control over ride quality, chassis movement, bottom-out resistance, and overall suspension performance.
2. Why choose a 3.0 bypass shock instead of a 2.5?
The larger 3.0 shock body provides greater oil volume, increased damping capacity, and improved heat management, making it ideal for larger tires, heavier vehicles, longer travel suspension systems, and aggressive driving conditions.
3. What are the benefits of a piggyback reservoir?
A piggyback reservoir increases oil capacity and cooling performance while eliminating external reservoir hoses, resulting in a cleaner and simpler installation.
4. What vehicles are best suited for a Radflo 3.0 4-Tube Bypass Shock?
These shocks are commonly used on rock bouncers, Ultra4 race cars, competition crawlers, desert race vehicles, and custom off-road builds requiring maximum suspension performance.
5. Are Radflo 3.0 4-Tube Bypass Shocks rebuildable?
Yes. Radflo bypass shocks are fully rebuildable and serviceable, allowing owners to maintain peak performance and make tuning adjustments as suspension needs evolve.
