What Are Remote Reservoir Coilover Shocks?
Remote reservoir coilovers combine a coil spring and shock absorber into a single suspension unit while adding an external reservoir connected by a high-pressure hose. Like emulsion coilovers, the spring supports the vehicle's weight and the shock controls suspension movement, but the remote reservoir significantly increases the amount of shock oil and nitrogen the system can hold. This additional fluid capacity improves cooling and allows the shock to maintain more consistent performance during extended trail rides, aggressive rock crawling, mud racing, desert racing, and other demanding off-road conditions.
Inside the shock, a precision-machined piston moves through hydraulic oil as the suspension cycles. The oil flows through carefully tuned valving that controls compression and rebound damping, while the remote reservoir houses additional oil and a floating piston that separates the oil from the nitrogen charge. This design reduces shock fade, improves heat dissipation, and provides more consistent suspension performance during repeated impacts and long periods of hard use. Remote reservoir coilovers are commonly found on rock crawlers, rock bouncers, Ultra4 cars, Jeep builds, overland vehicles, dune buggies, Sand Rails, mud trucks, mega trucks, and race vehicles because they offer a significant increase in suspension control, durability, and performance compared to standard emulsion shocks.
