2.0 Emulsion Coilover (x2) & Dual Rate Spring (x4) Package – 12" Travel
The 2.0 Emulsion Coilover & Dual-Rate Spring Package – 12" Travel combines two Radflo 2.0 emulsion coilovers with four Eibach 2.5" ID coilover springs for rock crawlers, trail buggies, Jeeps, and lightweight custom tube chassis builds. The compact 2.0" shock body and emulsion design keep packaging simple, while 12" of travel provides useful articulation without requiring the shock tower height or chassis space of a longer-travel setup.
Each coilover uses two springs to create a true dual-rate spring stack that can be tuned for ride height, initial compliance, and added support deeper into compression. The emulsion design keeps the oil and nitrogen charge inside the shock body, eliminating external reservoirs and hoses while retaining rebuildable, tunable damping performance for technical crawling, trail use, and recreational off-road suspension systems.
Includes:
- (2) Radflo 2.0 Emulsion Coilover Shocks – 12" Travel
- (4) Eibach 12" x 2.5" ID Coilover Springs – Two Springs Per Shock
- Dual-Rate Spring Hardware
- Universal Spherical Bearings
- Shock Mounting Hardware
Spring rates are selected when ordering from available 100–500 lb/in options.
Availability: Wide Open Design stocks a large selection of Radflo shocks and Eibach springs for immediate shipment. Some spring rates, custom valving configurations, and special-order suspension components may require additional production time.

Fitment
Best Suited For:
- Rock crawlers
- Trail buggies
- Jeep suspension builds
- Lightweight custom tube chassis vehicles
- Linked front or rear suspension systems
- Technical trail use
- Builds where reservoir packaging is limited
Fitment Notes:
- Universal package for custom front or rear suspension applications
- Verify 31.50" extended and 19.53" compressed mounting lengths before ordering
- Spring rates should be selected based on sprung weight, suspension geometry, shock angle, ride height, and intended use
- Dual-rate spring setup requires proper preload, crossover adjustment, and spring selection
- Cycle the suspension to verify chassis, tire, axle, link, and spring clearance
- Proper bump stop placement is required to prevent the coilover from becoming the suspension travel limiter
FAQ
What type of build is a 2.0" x 12" emulsion coilover package best suited for?
This package works well for rock crawlers, Jeeps, lightweight buggies, and trail rigs where usable articulation and compact packaging are more important than sustained high-speed shock cooling. The 12" travel length is easier to package than longer 14", 16", or 18" coilovers.
Why choose an emulsion coilover?
An emulsion coilover keeps the shock oil and nitrogen charge inside the main body, eliminating remote reservoirs and hoses. This simplifies installation and reduces packaging requirements while retaining tunable damping for crawling and trail use.
What makes this a dual-rate spring package?
Each coilover uses two springs, giving the package four springs total. The upper and lower springs work with the spring divider and crossover hardware to create a tunable dual-rate spring stack.
What is the advantage of dual-rate springs?
A dual-rate setup gives builders more control over how the suspension behaves through its travel. Proper spring selection and crossover adjustment can provide compliance early in compression while adding support as the suspension moves deeper into the stroke.
How do I select the correct spring rates?
Spring rates should be selected using sprung vehicle weight, weight distribution, suspension motion ratio, shock angle, desired ride height, and intended use. Learn how to calculate coilover spring rates here.
Are the shocks rebuildable and revalvable?
Yes. The shocks are fully rebuildable and revalvable, allowing damping characteristics to be serviced or changed as the vehicle setup evolves.
