Fitment
Universal Fitment for Custom Off-Road Suspension Systems
Designed for custom front or rear suspension applications requiring a compact 2.0" remote reservoir coilover with compatible mounting dimensions and spring configuration.
Common Applications:
- Jeep Suspension Builds
- Rock Crawlers & Trail Buggies
- Lightweight Tube-Chassis Vehicles
- Custom Off-Road Trucks
- Recreational Off-Road Vehicles
- Linked Suspension Systems
- Custom Front & Rear Coilover Conversions
Fitment & Installation Notes:
- Universal coilover designed for custom suspension applications.
- Available in 8", 10", 12", 14", 16", and 18" travel configurations.
- Verify compressed length, extended length, mounting width, and chassis clearance before ordering.
- Select shock travel based on suspension geometry, compression, and droop requirements.
- Spring rates must be matched to vehicle weight, suspension motion ratio, shock angle, and intended ride height.
- Dual-rate spring hardware is included; coil springs are sold separately.
- Confirm spring inside diameter, free length, and available preload adjustment before selecting springs.
- Route the remote reservoir hose clear of tires, exhaust, suspension links, steering components, and moving parts.
- Mount the remote reservoir in a secure location 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 2.0" remote reservoir coilover is a practical choice for builds where shock packaging, suspension weight, and available mounting space matter. Before selecting travel, cycle the suspension through full compression and droop, confirm shock mounting locations, and account for spring clearance and reservoir hose routing. Proper spring rates, crossover settings, and valving are just as important as shock travel when building a predictable suspension system.
FAQ
Why choose a remote reservoir coilover instead of an emulsion coilover?
A remote reservoir increases shock oil and gas capacity while separating the nitrogen charge from the damping fluid. This helps manage heat and maintain more consistent damping during repeated suspension cycling and extended off-road use.
Who is a Radflo 2.0 remote reservoir coilover best suited for?
The compact 2.0" body works well in Jeeps, rock crawlers, lightweight buggies, trail rigs, and custom trucks where mounting space and suspension weight are important. Heavier vehicles or builds exposed to sustained high-speed impacts may benefit from a larger 2.5" or 3.0" shock package.
Do Radflo 2.0 remote reservoir coilovers include springs?
No. Coil springs are sold separately so the correct rates and lengths can be selected for the vehicle's sprung weight, suspension geometry, shock angle, and intended use. Learn how to calculate coilover spring rates here.
Can this coilover be configured as a dual-rate setup?
Yes. Dual-rate spring hardware is included. A dual-rate configuration uses two coil springs with a spring slider and adjustable crossover hardware, allowing the spring rate transition to be tuned for the suspension.
How do I choose between 8", 10", 12", 14", 16", and 18" travel?
Select travel based on the suspension's actual compression and droop requirements, shock mounting geometry, and available chassis clearance. The compressed and extended lengths of the selected shock must be verified before installation.
Can ride height and spring preload be adjusted?
Yes. The threaded spring preload collar allows spring preload and ride height to be adjusted within the limits of the suspension design. Dual-rate crossover hardware also allows the spring transition point to be tuned.
Can Radflo remote reservoir coilovers be rebuilt or revalved?
Yes. Radflo coilovers are fully rebuildable and revalvable. Internal valving can be adjusted to suit different vehicle weights, spring packages, suspension geometry, and driving conditions.
What does the Radflo Freeflo Racing Piston do?
The Freeflo Racing Piston controls hydraulic fluid movement through the shock. Combined with velocity-sensitive deflective disc valving, it provides compression and rebound damping that can be tuned for the vehicle and terrain.
Does the remote reservoir need a specific mounting location?
The reservoir must be securely mounted with adequate clearance from exhaust heat, tires, steering components, and suspension movement. Hose routing should avoid sharp bends, abrasion, and contact with moving parts throughout suspension travel.
What nitrogen pressure does the Radflo 2.0 coilover use?
The supplied Radflo specifications list 200 PSI nitrogen pressure. Confirm the correct service pressure and charging procedure for the specific shock before making adjustments. Use dry nitrogen and appropriate high-pressure charging equipment.
