2.0 Remote Reservoir Coilover (x2) & Dual-Rate Spring (x4) Package – 12" Travel
The 2.0 Remote Reservoir Coilover & Dual-Rate Spring Package – 12" Travel combines two 12" travel Radflo 2.0 remote reservoir coilovers with four Eibach coilover springs to create a complete dual-rate suspension package for rock crawlers, Jeeps, trail rigs, and compact tube chassis builds. The 12" travel provides plenty of usable suspension movement without requiring the packaging space of a longer-travel shock, making this a strong option for builds where chassis clearance and controlled articulation matter.
With two springs per coilover, the package provides a true dual-rate spring stack that can be tuned around vehicle weight, ride height, suspension geometry, and intended use. The compact 2.0" shock body keeps weight and packaging under control, while the remote reservoirs increase oil capacity and help maintain consistent damping during repeated trail impacts and technical crawling.
Includes:
- (2) Radflo 2.0 Remote Reservoir Coilover Shocks – 12" Travel
- (4) Eibach 2.5" ID Coilover Springs – (2) Springs Per Shock
- Dual-Rate Spring Hardware
- Universal Spherical Bearings
- Shock Mounting Hardware
Spring rates are selected when ordering.
Availability: Wide Open Design stocks a large selection of Radflo shocks and Eibach springs for immediate shipment. Some shock configurations, spring rates, custom valving packages, and special-order components may require additional production time.

Fitment
Best Suited For:
- Rock crawlers
- Jeep suspension builds
- Trail rigs
- Compact trail buggies
- Lightweight tube chassis vehicles
- Linked suspension systems
- Custom builds where shock packaging is limited
Fitment Notes:
- Universal package for custom front or rear suspension applications
- 12" travel works well where usable articulation is needed without the packaging requirements of a longer-travel coilover
- Verify compressed and extended shock lengths before ordering
- Spring rates must be selected around sprung weight, suspension geometry, shock angle, and intended ride height
- Dual-rate spring setup requires proper preload, crossover adjustment, and spring selection
- Remote reservoir routing must remain clear of tires, exhaust, links, and other moving components
- Proper bump stop placement is required to prevent the coilover from becoming the suspension travel limiter
FAQ
What makes this a dual-rate coilover package?
Each coilover receives two springs, giving the package four springs total. The upper and lower springs work with the coilover's divider and crossover hardware to provide a tunable dual-rate spring stack.
Why choose a 12" travel coilover?
A 12" coilover provides substantial usable suspension travel while remaining easier to package than longer 14", 16", or 18" shocks. This makes it especially useful for rock crawlers, Jeeps, trail rigs, and compact tube chassis builds where articulation and chassis clearance need to stay balanced.
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.
What does the remote reservoir do?
The remote reservoir adds fluid and nitrogen capacity outside the compact 2.0" shock body. The additional capacity helps manage shock temperature and maintain more consistent damping during repeated suspension cycling.
Can ride height and the dual-rate transition be adjusted?
Yes. The threaded preload collar is used to adjust spring preload, while the crossover hardware can be positioned to tune when the suspension transitions through the dual-rate spring stack.
Are these shocks rebuildable and revalvable?
Yes. The shocks are fully rebuildable and revalvable, allowing the damping setup to be serviced or changed as the vehicle and suspension setup evolve.
