Radflo 2.5 Emulsion Coilover Shock | Off-Road Suspension
6CE-001-00
The Radflo 2.5 Emulsion Coilover Shock is designed for builders who need more suspension control, greater oil volume, and increased damping performance than a traditional 2.0 coilover can provide. Built around a large 2.5" shock body and heavy-duty 7/8" shaft, this coilover is engineered for heavier vehicles, larger tires, aggressive terrain, and high-performance off-road driving.
Whether you're building a rock bouncer, Ultra4 car, prerunner, Jeep, trail rig, or custom truck, the Radflo 2.5 Coilover delivers the suspension performance needed to handle bigger impacts, rough terrain, and demanding off-road conditions.
The larger shock body increases fluid capacity and heat dissipation compared to smaller coilovers, helping maintain consistent damping performance during extended trail rides, competition use, and aggressive off-road driving. Unlike air shocks or factory replacement shocks, Radflo coilovers allow builders to tune ride height, suspension preload, and spring rates to match vehicle weight and intended use.
Includes:
- (1) Radflo 2.0 Coilover Shock
- Dual Rate Spring Hardware
- Universal Spherical Bearing & Mounting Hardware
- Eibach Coilover Springs Sold Separately
Availability Note: As the #1 Stocking Warehouse for Radflo Performance Shocks, we maintain the largest on-shelf inventory of off-road coilover shocks and springs in the industry. While we keep the most popular travel lengths ready for immediate shipment, certain Radflo coilovers, custom valving packages, or special-order suspension components may require additional production time. Please allow approximately 4–6 weeks for manufacturing and shipment of these products.
We are committed to getting your rig on the trail as fast as possible. If your build schedule is critical, please call us to confirm real-time inventory before placing your order. If you need help selecting the correct coilover shocks, coilover springs, or complete off-road suspension system for your build, our team is happy to help.

Tech Insight
What is the advantage of a Radflo 2.5 Coilover over a Radflo 2.0 Coilover?
The larger 2.5" shock body holds more oil, allowing for improved damping control, better heat management, and more consistent performance under aggressive off-road use. A 2.5 coilover is often preferred for heavier vehicles, larger tires, racing applications, and high-horsepower builds.
What is the difference between an emulsion coilover shock and a remote reservoir shock?
An emulsion coilover shock combines the oil and nitrogen charge in a single shock body, creating a compact and cost-effective suspension solution. Remote reservoir shocks provide additional oil capacity and cooling for sustained high-speed racing applications. For trail riding, rock crawling, and most off-road suspension systems, an emulsion coilover offers excellent performance, durability, and adjustability.
Do these coilover shocks include springs?
No. Springs are sold separately so builders can select the correct coilover springs for their vehicle weight and suspension design. Eibach springs are a popular choice for Radflo coilover applications.
What types of vehicles benefit most from Radflo 2.5 Coilovers?
Radflo 2.5 coilovers are commonly used on rock bouncers, Ultra4 cars, prerunners, Jeeps, off-road race trucks, and heavy trail rigs where suspension demands exceed what a smaller shock can comfortably handle.
Are Radflo 2.5 Coilovers rebuildable?
Yes. Like all Radflo shocks, the 2.5 Emulsion Coilover is fully rebuildable and serviceable. Regular maintenance helps maximize performance and extend shock life in demanding off-road environments.
