Radflo 2.5 3-Tube Bypass Shock w/ Remote Res. (30" Hose & 3/4" Tubes)
6BP-304-1R
The WOD Custom Radflo 2.5 3-Tube Bypass Shock with Remote Reservoir is built for rock crawlers, Ultra4 cars, rock bouncers, desert trucks, trail rigs, and custom off-road vehicles that need greater suspension control and tuning capability than a conventional shock. This 14" travel bypass shock combines velocity-sensitive internal valving with three external 3/4" bypass tubes to provide position-sensitive damping throughout the shock travel.
The upgraded 3/4" bypass tubes provide increased oil-flow capacity, while the remote reservoir adds fluid volume and helps manage heat during sustained hard use. A 30" high-pressure reservoir hose provides additional flexibility for reservoir placement in tight chassis layouts. Each shock can be custom valved around vehicle weight, suspension geometry, and intended use.

Fitment
Universal fitment for custom off-road suspension applications including:
- Rock Crawlers
- Ultra4 Cars
- Rock Bouncers
- Desert Trucks
- Prerunners
- Custom Tube Chassis Vehicles
- Heavy-Duty Trail Rigs
Fitment Notes:
- Fitment is determined by shock travel, mounting dimensions, suspension geometry, and available clearance.
- Allow adequate clearance around the shock body and external bypass tubes throughout the complete suspension cycle.
- Verify reservoir hose routing and remote reservoir mounting clearance before installation.
- Final valving should be matched to vehicle weight, suspension geometry, and intended use.
FAQ
What is the difference between a 3-tube and 4-tube bypass shock?
Both use external bypass tubes to create position-sensitive damping zones. A 4-tube configuration adds another bypass circuit for additional control over how damping is divided throughout the shock travel. A 3-tube bypass still provides substantial tuning capability in a simpler package that works well for rock crawling, trail, and racing applications.
What does a bypass shock do?
A bypass shock combines velocity-sensitive internal valving with position-sensitive external damping. Oil is routed through external bypass tubes at specific points in the shock travel, allowing damping to change based on shock position. This provides control over different portions of the suspension stroke instead of relying only on the internal piston and valving.
Do I still need coilovers if I run bypass shocks?
In most custom suspension applications, yes. A bypass shock primarily controls suspension movement and does not normally support vehicle weight. Coilovers or another spring system support the vehicle while the bypass shocks provide additional damping and suspension control.
What is the advantage of the upgraded 3/4" bypass tubes?
The larger 3/4" bypass tubes increase oil-flow capacity through the external bypass circuits. This provides additional fluid-flow capability when controlling damping through different areas of the shock travel, making them well suited for demanding off-road and racing applications.
What is the advantage of the 30" reservoir hose?
The 30" high-pressure hose provides greater flexibility when locating the remote reservoir. This allows builders to position the reservoir where packaging, protection, cooling, and service access work best within a custom chassis or suspension layout.
