This Radflo 2.5 Emulsion Coilover Shock & Eibach Spring Package delivers premium off-road performance in a simplified, race-proven configuration. Designed for serious trail rigs, rock crawlers, and competition builds, this package combines Radflos high-performance 2.5 emulsion coilovers with matched 3.0 Eibach dual-rate springs for a balanced blend of small-bump compliance, bottom-out control, and durability.

Built for high-travel suspension systems, these coilovers feature Radflos precision valving technology and heavy-duty Nitro Steel shafts for strength under extreme abuse. Paired with USA-made Eibach coil springs, this setup provides consistent damping, improved traction, and the tunability required for aggressive off-road use without the added complexity of external reservoirs.

Includes:

• (2) Radflo Suspension Technology 2.5" Emulsion Coilover Shocks
• (4) Eibach 3.0" Dual-Rate Coil Springs

Tech Insight

Emulsion shocks offer a streamlined design compared to remote reservoir systems, making them ideal for builds where packaging space is limited while still delivering excellent damping performance. Radflos velocity-sensitive valving and precision machining ensure consistent control across rough terrain.

Pairing these shocks with dual-rate Eibach springs gives you progressive performancesoft initial travel for traction and comfort, transitioning into a firmer rate for stability during hard hits or high-speed compression. This combination is ideal for rock crawlers and aggressive trail machines that demand both articulation and bottom-out resistance.
