Radflo 3.0 Remote Reservoir Smooth Body Shock - 1" Shaft
7SR-001-00
The Radflo 3.0 Remote Reservoir Smooth Body Shock delivers heavy-duty damping control and heat management for rock bouncers, Ultra4 race cars, desert trucks, prerunners, and custom off-road suspension systems. Featuring a 3.0" shock body, 1" Nitro Steel shaft, and remote reservoir, this performance shock provides increased oil capacity and consistent damping during repeated suspension cycling and severe off-road impacts. Available in 10", 12", 14", and 16" travel lengths, it is designed for demanding front or rear suspension applications where durability, suspension control, and fade resistance are priorities.
Built around Radflo's Freeflo Racing Piston and velocity-sensitive deflective disc valving, the 3.0 smooth body shock can be custom valved to match vehicle weight, suspension geometry, and intended terrain. The remote reservoir provides additional fluid capacity and separates the nitrogen charge from the damping oil, helping maintain consistent performance during extended off-road use. Fully rebuildable and revalvable, this shock is well suited for secondary damping alongside coilovers, high-performance leaf spring suspensions, and custom long-travel builds.
Includes:
- (1) Radflo 3.0 Remote Reservoir Smooth Body Shock – Selected Travel Length
- Remote Reservoir Assembly
- Universal Spherical Bearings
- Mounting Hardware
Note: Sold individually. This is a smooth body shock without coilover spring hardware. Springs, coilovers, and custom mounting brackets are sold separately.
Availability: Wide Open Design stocks a large selection of Radflo shocks and springs. Some travel lengths, custom valving configurations, and special-order suspension components may require additional production time.

Fitment
Universal Fitment for Custom Off-Road Suspension Systems
Designed for custom front or rear suspension applications requiring a 3.0" remote reservoir smooth body shock with compatible mounting dimensions and appropriate valving.
Common Applications:
- Rock Bouncers & Competition Rock Crawlers
- Ultra4 Race Cars
- Desert Racing Trucks & Prerunners
- Custom Tube-Chassis Buggies
- Long-Travel Suspension Systems
- Heavy-Duty Off-Road Vehicles
- Secondary Shock Applications Alongside Coilovers
- Performance Leaf Spring Suspension Systems
Fitment & Installation Notes:
- Universal smooth body shock designed for custom suspension applications.
- Available in 10", 12", 14", and 16" travel configurations.
- Verify compressed length, extended length, bearing size, mounting width, and chassis clearance before ordering.
- Select shock travel based on suspension geometry and measured compression and droop requirements.
- Custom valving should be matched to vehicle weight, suspension leverage, shock angle, and intended terrain.
- Can be used alongside coilovers or other spring systems to provide additional damping control.
- Route the remote reservoir hose clear of exhaust heat, tires, steering components, suspension links, and other moving parts.
- Mount the reservoir securely with adequate clearance and protection.
- Proper bump stop placement is required to prevent the shock from becoming the suspension's compression limiter.
- Custom shock tabs, brackets, and chassis mounts may be required.
- Professional suspension setup and tuning are recommended.
Builder Note: The Radflo 3.0 smooth body shock is a strong option for heavy off-road vehicles and secondary shock packages where additional damping capacity and heat management are important. Before selecting travel, cycle the suspension through full compression and droop, confirm shock mounting locations, and plan reservoir hose routing. Shock valving should be matched to the complete suspension system rather than selected by travel length alone.
FAQ
What is a Radflo smooth body shock?
A smooth body shock is a hydraulic damper that uses internal piston and valving components to control suspension movement. Unlike an external bypass shock, it does not have external bypass tubes or position-sensitive bypass zones. It can be used with coilovers, leaf springs, or other suspension spring systems.
What are the benefits of a remote reservoir shock?
A remote reservoir increases oil and gas capacity while separating the nitrogen charge from the damping fluid. This helps manage heat and maintain consistent damping during repeated suspension cycling and extended off-road use.
Why choose a Radflo 3.0 shock instead of a 2.5 shock?
The larger 3.0" shock body provides increased oil capacity and greater potential for heat management and damping performance. This makes it a strong choice for heavier vehicles, high-speed off-road racing, and demanding suspension applications where shocks experience repeated high-energy impacts.
Do Radflo 3.0 smooth body shocks include coil springs?
No. Smooth body shocks do not include coilover spring hardware or springs. They are designed to provide damping control alongside a separate suspension spring system.
Can a smooth body shock be used as a secondary shock?
Yes. Smooth body shocks are commonly used alongside coilovers or other primary suspension systems to provide additional compression and rebound damping. Proper valving and mounting geometry are important when combining multiple shocks.
How do I choose between 10", 12", 14", and 16" travel?
Select travel based on measured suspension compression and droop, shock mounting geometry, and available chassis clearance. Verify the compressed and extended lengths of the selected shock before installation.
Can Radflo 3.0 smooth body shocks be rebuilt and revalved?
Yes. Radflo 3.0 shocks are fully rebuildable and revalvable. Internal valving can be adjusted to match different vehicle weights, suspension configurations, and driving conditions.
What is the Radflo Freeflo Racing Piston?
The Freeflo Racing Piston is Radflo's aluminum piston design that controls hydraulic fluid movement through the shock. Combined with velocity-sensitive deflective disc valving, it provides tunable compression and rebound damping for different suspension applications.
What nitrogen pressure does the Radflo 3.0 shock use?
The supplied Radflo specifications list 200 PSI nitrogen pressure. Confirm the appropriate pressure and charging procedure for the specific shock before making adjustments. Use dry nitrogen and suitable high-pressure charging equipment.
Does the Radflo 3.0 shock include mounting hardware?
Yes. The supplied product specifications list universal spherical bearings and mounting hardware. Custom chassis brackets and shock mounting tabs may be required for installation.
