2.0 Emulsion Coilover (x2) & Eibach Spring (x2) Package – 16" Travel
The 2.0 Emulsion Coilover & Spring Package – 16" Travel combines two 16" travel Radflo 2.0 emulsion coilovers with two Eibach 2.5" ID coilover springs for lightweight rock crawlers, trail buggies, and custom tube chassis builds that need substantial suspension travel in a compact package. The 2.0" shock body keeps weight and overall size down, while the emulsion design eliminates remote reservoirs and hoses for simpler mounting in tight chassis layouts.
With one 16" spring per coilover, this package provides a straightforward single-spring suspension setup with adjustable preload and selectable spring rates from 100–500 lb/in. The long 16" shock travel makes it best suited for properly designed linked suspensions where articulation and wheel travel are priorities, while the rebuildable and revalvable coilovers allow damping to be matched to vehicle weight, suspension geometry, and intended use.
Includes:
- (2) Radflo 2.0 Emulsion Coilover Shocks – 16" Travel
- (2) Eibach 16" x 2.5" ID Coilover Springs – One Spring Per Shock
- Universal Spherical Bearings
- Shock Mounting Hardware
Spring rates are selected when ordering from available 100–500 lb/in options.
Availability Note: As the #1 stocking warehouse for Radflo Performance Shocks, we maintain one of the largest inventories of Radflo coilovers and Eibach springs in the industry. While many popular configurations are available for immediate shipment, certain spring rates, custom valving packages, and special-order suspension components may require additional production time.

Fitment
Best Suited For:
- Lightweight long-travel rock crawlers
- Trail buggies
- Custom tube chassis vehicles
- High-articulation linked suspension systems
- Front or rear coilover applications
- Builds where compact shock packaging is a priority
Fitment Notes:
- Universal package for custom front or rear suspension applications
- 16" travel requires adequate chassis, axle, tire, link, and driveshaft clearance throughout the suspension cycle
- Spring rate should be selected based on sprung weight, suspension geometry, shock angle, ride height, and intended use
- This package includes one spring per shock and is not configured as a dual-rate spring package
- Cycle the complete suspension before finalizing shock mounts and spring clearance
- Proper bump stop placement is required to protect the coilover from bottoming mechanically
FAQ
What type of build is a 2.0" x 16" coilover best suited for?
This package is best suited for lightweight rock crawlers, trail buggies, and custom tube chassis builds that need substantial wheel travel without the size and weight of a larger 2.5" coilover. The 16" travel requires a suspension specifically designed to take advantage of the additional articulation.
Why choose an emulsion coilover instead of a remote reservoir shock?
An emulsion coilover keeps the oil and nitrogen charge within the shock body, eliminating the external reservoir and hose. This simplifies installation and packaging while still providing tunable damping for crawling and recreational trail use.
Is this a dual-rate spring package?
No. This package includes two coilovers and two springs, providing one 16" spring per shock. A true dual-rate setup requires two springs per coilover along with the appropriate crossover hardware.
How do I select the correct spring rate?
Spring rate should be based on sprung vehicle weight, weight distribution, suspension geometry, shock angle, desired ride height, and intended use. Learn how to calculate coilover spring rates here.
Are these coilovers rebuildable and revalvable?
Yes. The shocks are fully rebuildable and revalvable, allowing damping characteristics to be serviced or changed as the vehicle setup evolves.
