What are emulsion coilovers?
Emulsion coilover shocks combine a shock absorber and coil spring into a single suspension unit, making them one of the most popular suspension choices for Jeeps, rock crawlers, trail rigs, UTVs, dune buggies, mud trucks, and custom off-road vehicles. Unlike remote reservoir shocks, an emulsion shock stores both the shock oil and nitrogen gas inside the main shock body. The coil spring supports the vehicle's weight while the shock controls suspension movement, helping keep the tires planted and the vehicle stable over rough terrain.
Inside the shock, the piston moves through the oil as the suspension cycles up and down. This movement forces oil through precision valving that controls compression and rebound damping. The nitrogen charge helps prevent cavitation and maintains consistent performance while allowing room for the shock shaft to enter the body during compression. Emulsion coilovers are valued for their simplicity, affordability, compact packaging, and excellent all-around performance. They are an ideal choice for trail riding, rock crawling, overland builds, dune buggies, and many off-road applications where reliability and suspension control are more important than the extreme heat management required by race-level suspension systems.
