Radflo 2.0 Emulsion + Eibach Spring Package • 14" Travel • 2 Shocks + 2 Springs
The Radflo 2.0 Emulsion + Eibach Spring Package combines two 14" travel Radflo emulsion coilover shocks with two 14" Eibach coilover springs for custom off-road suspension systems. Featuring 2.0" shock bodies and heavy-duty 7/8" Nitro Steel shafts, these coilovers provide tunable damping performance in a compact, reservoir-free design for demanding trail use and rock crawling.
Each Radflo coilover features velocity-sensitive valving and adjustable spring hardware for suspension tuning. The package includes two Eibach 2.5" ID coilover springs with selectable rates from 100 to 350 lb/in to match vehicle weight and suspension requirements. Both springs are supplied in the selected rate, providing a single-spring configuration for each shock. The emulsion design eliminates external reservoirs and hoses, while the rebuildable and revalvable shocks provide long-term serviceability.
Includes:
- (2) Radflo 2.0 Emulsion Coilover Shocks – 14" Travel
- (2) Eibach Coilover Springs – 14" Length x 2.5" ID
- Coilover Spring Hardware Included with Radflo Shocks
- Universal Spherical Bearings & Mounting Hardware
Spring Rate Selection: Select your desired Eibach spring rate from the available options. Both springs in this package will be supplied in the selected rate.
Shipping & Assembly: This package ships with the Radflo shocks and Eibach springs packaged separately. Springs are not installed on the shocks. Assembly and suspension setup are required.
Availability: Wide Open Design stocks a selection of Radflo shocks and Eibach springs. Some spring rates, custom valving configurations, and special-order components may require additional production time.

Fitment
Universal Fitment for Custom Off-Road Suspension Systems
This package is intended for custom front or rear coilover suspension applications requiring 14" travel Radflo 2.0 emulsion shocks and compatible 2.5" ID Eibach springs.
Common Applications:
- Rock Crawlers & Trail Buggies
- Custom Tube-Chassis Buggies
- Jeep Suspension Builds
- Ultra4-Style Off-Road Builds
- Linked Front & Rear Suspension Systems
- Custom Long-Travel Suspension Builds
Fitment & Installation Notes:
- Universal coilover package requiring custom suspension mounting and setup.
- Includes two 14" travel shocks and two 14" long, 2.5" ID Eibach springs.
- Both springs are supplied in the customer-selected spring rate.
- Verify 35.43" extended length, 21.50" compressed length, mounting dimensions, and chassis clearance before ordering.
- Select spring rate based on vehicle sprung weight, shock angle, suspension motion ratio, and intended ride height.
- Confirm spring preload, available compression, and spring clearance throughout suspension travel.
- Cycle the suspension to verify chassis, tire, axle, driveshaft, and suspension link clearance.
- Proper bump stop placement is required to prevent shocks from becoming the suspension's compression limit.
- Custom shock tabs, mounting brackets, and chassis fabrication may be required.
- Shocks and springs ship unassembled and require installation and suspension setup.
FAQ
What is included in this Radflo and Eibach coilover package?
The package includes two Radflo 2.0 emulsion coilover shocks with 14" travel, two Eibach 14" x 2.5" ID coilover springs in the selected rate, spring hardware, spherical bearings, and mounting hardware.
How do I select my Eibach spring rate?
Select your spring rate from the available options. Both springs in the package will be supplied in the same selected rate. Available spring rates range from 100 to 350 lb/in.
What is the difference between an emulsion and remote reservoir coilover?
An emulsion coilover contains its oil and nitrogen charge within the shock body, eliminating the external reservoir and hose. Remote reservoir shocks provide additional fluid and gas capacity and are often preferred for applications with more sustained or repeated high-speed suspension cycling.
Are these single-rate or dual-rate coilovers?
This package includes one Eibach spring per Radflo shock, creating a single-spring configuration. A complete dual-rate spring setup requires two springs per shock and compatible dual-rate hardware.
Do the shocks and springs arrive assembled?
No. The Radflo shocks and Eibach springs are packaged separately. Springs are not installed on the shocks, and assembly and suspension setup are required.
Why choose a 2.0" coilover instead of a 2.5" coilover?
A 2.0" coilover offers a more compact shock body for suspension systems where packaging space and vehicle weight favor a smaller damper. Spring selection and shock valving should be matched to the vehicle's suspension requirements.
How do I know if 14" travel is correct for my suspension?
Shock travel must match the suspension's measured compression and droop requirements. The supplied 14" shock dimensions are 35.43" extended and 21.50" compressed. Verify mounting geometry and available clearance before ordering.
Can I adjust ride height and spring preload?
Yes. Radflo coilovers feature adjustable spring preload hardware, allowing builders to fine-tune ride height and preload within the limits of the suspension design and selected spring package.
Can the Radflo emulsion shocks be rebuilt or revalved?
Yes. Radflo 2.0 emulsion coilovers are rebuildable and revalvable, allowing the damping setup to be serviced or adjusted for changes in vehicle weight, suspension geometry, and intended use.
How do I calculate the correct coilover spring rate?
Spring rate selection depends on sprung vehicle weight, shock angle, suspension motion ratio, and desired ride height. Watch our spring rate calculation guide for help understanding coilover spring selection.
