The Radflo 2.5 3-Tube Bypass Shock with Piggyback Reservoir delivers race-proven suspension control in a compact, self-contained package. Designed for rock crawlers, rock bouncers, trail rigs, Ultra4 cars, and custom off-road vehicles, this shock combines the tunability of a bypass shock with the simplicity of an integrated piggyback reservoir.
Unlike standard coilover shocks, bypass shocks allow suspension damping to change throughout the shock stroke. This gives builders the ability to create a smoother ride over rough terrain while increasing control near full compression and extension. The result is improved traction, greater stability, and better overall suspension performance.
The piggyback reservoir eliminates the need for external reservoir hoses while still increasing oil capacity and cooling performance. This creates a cleaner installation and simplifies packaging in vehicles where space is limited. For builders looking to improve suspension performance without adding additional hose routing and mounting brackets, the Radflo 2.5 Piggyback Bypass Shock offers an excellent balance of performance, simplicity, and durability.

Tech Insight
What is the difference between a piggyback reservoir and a remote reservoir?
A piggyback reservoir is mounted directly to the shock body, eliminating the need for external reservoir hoses. This simplifies installation while still providing additional oil capacity and cooling benefits.
2. What are the advantages of a 3-tube bypass shock?
The three externally adjustable bypass tubes create multiple damping zones throughout the shock stroke, allowing improved ride quality, traction, chassis control, and bottom-out resistance.
3. Is a piggyback shock easier to install than a remote reservoir shock?
Yes. Because the reservoir is integrated into the shock body, there are no hoses to route and no separate reservoir mounts to fabricate.
4. What vehicles work best with a Radflo 2.5 Piggyback Bypass Shock?
These shocks are commonly used on rock crawlers, Jeeps, trail rigs, rock bouncers, Ultra4 cars, and custom off-road vehicles where suspension performance and compact packaging are both important.
5. Are Radflo Piggyback Bypass Shocks rebuildable?
Yes. Like all Radflo shocks, these shocks are fully rebuildable and serviceable, allowing long-term maintenance and suspension tuning as vehicle needs evolve.
