The Radflo 2.5 3-Tube Bypass Shock with Piggyback Reservoir delivers race-proven suspension control in a compact, self-contained package for rock crawlers, rock bouncers, trail rigs, Ultra4 cars, and custom off-road vehicles. Its external bypass design allows damping to change throughout the shock travel, providing a smoother response over rough terrain while increasing control near compression and extension for improved traction, stability, and handling.
The piggyback reservoir increases oil capacity and cooling performance without external reservoir hoses, creating a cleaner installation with fewer components to route and mount. For builders working with limited chassis space, this 2.5" bypass shock provides an excellent balance of adjustability, performance, durability, and compact packaging.

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.
