Abstract: A coil spring assembly is disclosed for use with motor vehicle suspension systems in which a portion of the wire coils of the coil spring is covered by a flexible hose or tube. Coil springs which could use such hoses include those having a tapered wire diameter wherein one end of the coil spring's wire has a smaller diameter than at other portions of its length. The flexible hose is made of a material which has sufficient resiliency to first be stretched as it is installed onto the wire of the coil spring, and then will naturally return back to near its original non-stressed diameter to tightly fit around the diameter of the wire at both ends of the hose. The resulting tight fit retains lubricant and anti-corrosive compounds inside the hose, and keeps moisture and dirt from entering the interior of the hose.
