Radflo 3.0 Bypass Shock w/ Piggyback Reservoir – 3-Tube, 1” Shaft
7BP-301-00
The Radflo 3.0 3-Tube Bypass Shock with Piggyback Reservoir is built for off-road vehicles that demand maximum suspension control, durability, and impact absorption. Featuring a massive 3.0" shock body, heavy-duty 1" shaft, three externally adjustable bypass tubes, and an integrated piggyback reservoir, this shock is designed for rock bouncers, Ultra4 race cars, competition crawlers, and high-horsepower off-road builds.
As vehicle weight, tire size, suspension travel, and horsepower increase, suspension control becomes critical. The Radflo 3.0 Bypass Shock provides significantly greater damping capacity than smaller shocks, helping control chassis movement, improve traction, and maintain stability through rough terrain, hard landings, and aggressive driving conditions.
The integrated piggyback reservoir increases oil volume while eliminating external reservoir hoses, creating a clean and compact installation without sacrificing performance. Whether you're attacking steep hill climbs, racing through technical terrain, or building a top-tier trail rig, the Radflo 3.0 Piggyback Bypass delivers the control needed to keep your suspension working at its highest level.
Includes:
- (1) Radflo 3.0 Off-Road Bypass Shock
- Integrated Piggyback Reservoir
- (3) External Bypass Tubes
- Universal Spherical Bearing & Mounting Hardware
Availability Note: As the #1 stocking warehouse for Radflo Performance Shocks, we maintain one of the largest inventories of Radflo coilovers and springs in the industry. While many popular shock configurations are available for immediate shipment, certain coilovers, custom valving packages, and special-order suspension components may require 4–6 weeks for production and delivery.

Tech Insight
1. What makes a Radflo 3.0 Bypass Shock different from a 2.5 Bypass Shock?
The 3.0 shock body provides greater oil volume and damping capacity, while the 1" shaft increases strength. This makes the 3.0 better suited for larger tires, heavier vehicles, higher speeds, and more aggressive off-road use.
2. Why choose a piggyback reservoir instead of a remote reservoir?
A piggyback reservoir eliminates external hoses and separate mounting brackets while still increasing oil capacity and cooling performance. This creates a cleaner and simpler installation.
3. What are the benefits of a bypass shock?
Bypass shocks create multiple damping zones throughout suspension travel, improving ride quality, traction, chassis stability, and bottom-out resistance compared to traditional shock absorbers.
4. What vehicles are best suited for a Radflo 3.0 Piggyback Bypass Shock?
These shocks are commonly used on rock bouncers, Ultra4 race cars, competition crawlers, long-travel vehicles, and custom off-road builds running large tires and high-horsepower drivetrains.
5. Are Radflo 3.0 Bypass Shocks rebuildable?
Yes. Radflo bypass shocks are fully rebuildable and serviceable, allowing maintenance, tuning, and rebuilding to keep the suspension performing at its best.
