2.5 Emulsion Coilover (x2) & Eibach Spring (x2) Package – 14" Travel
The 2.5 Emulsion Coilover & Spring Package – 14" Travel combines two Radflo 2.5 emulsion coilovers with two Eibach 3.0" ID coilover springs for rock crawlers, trail buggies, rock bouncers, and custom tube chassis vehicles that need increased damping capacity and useful suspension travel in a simple package. The larger 2.5" shock body provides more oil volume and damping capability than a 2.0" coilover, while 14" of travel gives properly designed linked suspensions room for substantial articulation without the packaging demands of a longer 16" shock.
Each coilover uses one 14" spring with selectable rates from 100–500 lb/in for straightforward ride-height and spring-rate tuning. The emulsion design keeps the oil and nitrogen charge inside the shock body, eliminating remote reservoirs and hoses while retaining rebuildable, revalvable damping performance for technical crawling, trail use, and aggressive off-road suspension systems.
Includes:
- (2) Radflo 2.5 Emulsion Coilover Shocks – 14" Travel
- (2) Eibach 14" x 3.0" ID Coilover Springs – One Spring Per Shock
- Coilover 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
- Rock bouncers
- Custom tube chassis vehicles
- Linked front or rear suspension systems
- Heavier recreational off-road builds
- Applications needing more shock capacity without remote reservoir packaging
Fitment Notes:
- Universal package for custom front or rear suspension applications
- Verify 35.43" extended and 21.50" compressed mounting lengths before ordering
- Spring rate should be selected based on sprung weight, suspension geometry, shock angle, ride height, and intended use
- Cycle the suspension to verify chassis, tire, axle, link, driveshaft, 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 2.5" x 14" emulsion coilover package best suited for?
This package is a strong fit for rock crawlers, trail buggies, rock bouncers, and custom chassis that need increased shock capacity and articulation without the additional packaging of a remote reservoir system.
Why choose a 2.5" coilover instead of a 2.0" coilover?
The larger 2.5" shock body provides increased oil volume and damping capacity. This is especially useful on heavier vehicles, larger-tire builds, and suspension systems subjected to greater loads and repeated impacts.
Why choose 14" travel?
A 14" coilover provides more potential suspension movement than a 12" shock while remaining easier to package than a 16" or 18" configuration. It is a common middle ground for purpose-built crawlers and trail buggies that need additional articulation without excessive shock tower height.
Is this a dual-rate spring package?
No. This package includes two springs total, with one 14" spring installed on each coilover. A dual-rate package uses two springs per shock and four springs total.
Why choose an emulsion coilover instead of a remote reservoir shock?
An emulsion coilover keeps the oil and nitrogen charge inside the shock body, eliminating external reservoirs and hoses. This simplifies packaging and works well for crawling and trail-focused applications where sustained high-speed heat management is not the primary concern.
How do I select the correct spring rate?
Spring rate 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.
