2.0 Remote Reservoir Coilover (x2) & Dual Rate Spring (x4) Package – 16" Travel
The 2.0 Remote Reservoir Coilover & Dual-Rate Spring Package – 16" Travel combines two Radflo 2.0 remote reservoir coilovers with four Eibach 2.5" ID coilover springs for long-travel rock crawlers, lightweight trail buggies, and custom tube chassis suspension systems. The 2.0" shock body keeps packaging compact while 16" of travel gives properly designed linked suspensions substantial articulation and wheel movement without stepping up to the size and weight of a larger 2.5" coilover.
Each coilover uses two 16" springs to create a tunable dual-rate spring stack, allowing builders to balance initial suspension compliance with the support needed deeper into travel. The remote reservoirs increase fluid capacity and help manage heat during extended suspension cycling, making this package especially well suited for lightweight long-travel builds that need articulation, spring-rate tuning, and consistent damping in a compact package.
Includes:
- (2) Radflo 2.0 Remote Reservoir Coilover Shocks – 16" Travel
- (4) Eibach 16" 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 Note: As the #1 stocking warehouse for Radflo Performance Shocks, we maintain one of the largest inventories of Radflo coilovers and springs in the industry. While many popular shock and spring 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:
- Long-travel rock crawlers
- Lightweight trail buggies
- Custom tube chassis vehicles
- Linked front or rear suspension systems
- High-articulation trail builds
- Applications where compact shock packaging matters
Fitment Notes:
- Universal package for custom front or rear suspension applications
- Verify shock mounting dimensions and available suspension travel before ordering
- 16" shock travel requires sufficient chassis, axle, tire, link, and driveshaft clearance throughout the suspension cycle
- Primary and secondary spring rates should be selected based on sprung weight, suspension geometry, shock angle, and intended use
- Cycle the suspension before finalizing shock mounts and spring clearance
- Remote reservoir routing must remain clear of tires, exhaust, suspension 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 package different from a shorter 2.0 coilover package?
The 16" travel configuration is intended for suspension systems designed around substantially more articulation and wheel travel. It retains the compact 2.0" shock body while giving long-travel crawler and buggy builds more suspension stroke to work with.
What is the advantage of using four springs with two coilovers?
Each coilover uses two springs to create a dual-rate spring stack. This gives builders greater control over initial suspension compliance, ride height, crossover point, and support deeper into the suspension travel.
When should I choose a 2.0 coilover instead of a 2.5?
A 2.0 coilover is a strong choice for lighter vehicles and builds where packaging, weight, and clearance are priorities. Larger and heavier vehicles, higher-speed applications, or suspensions subjected to greater heat and repeated impacts may benefit from the additional damping and oil capacity of a 2.5" shock.
Why use a remote reservoir on a 2.0 coilover?
The reservoir increases fluid capacity outside the main shock body and helps manage heat during repeated suspension cycling. This gives a compact 2.0" coilover additional performance capacity without requiring the larger physical package of a 2.5" shock body.
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.
