The Radflo 2.5 Emulsion Coilover with 7/8″ shaft is built for serious off-road enthusiasts who demand strength, simplicity, and tunability in one integrated package. Designed with Radflo’s race proven construction and built to order philosophy, this 2.5″ diameter coil-over delivers dependable performance across rock crawling, trail, and high speed terrain applications.
This emulsion style shock combines nitrogen and oil in a single chamber, offering a compact, clean installation without an external reservoir. Featuring Radflo’s exclusive Freeflo Racing Piston and velocity sensitive valving, damping automatically adapts to changing terrain for improved control and ride quality.
Each shock is uniquely valved to match your vehicle’s weight, suspension geometry, and intended use. Dual-rate spring hardware is included (springs sold separately), allowing you to configure a high performance suspension setup tailored to your build.
Includes:
- (1) Radflo 2.5 Emulsion Coilover Shock
- Dual Spring Hardware
- OE Location Mounting Hardware
*Sold Individually.
**Springs Sold Separately.
Availability Note: As the #1 Stocking Warehouse for Radflo, we maintain the largest on-shelf inventory of shocks and spring packages in the industry. While we keep the most popular lengths (like our 12", 14", and 16" kits) ready for immediate shipment, the high demand for specialized sizes can occasionally result in a 4-6 week lead time.
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.

An emulsion shock combines oil and nitrogen in a single chamber, offering a simpler, more compact design compared to remote reservoir shocks. This makes it ideal for applications with limited mounting space while still delivering consistent damping performance.
The 2.5″ body increases oil volume for improved heat management over smaller shocks, while the 7/8″ Nitro Steel shaft provides excellent strength-to-weight balance. Radflo’s velocity-sensitive deflective disc valving and Freeflo Racing Piston automatically adapt to terrain changes, delivering controlled compression and rebound across varying conditions.
