Renthal R4 520 130L SRS Road Chain

Renthal's R4 SRS Road chain is a specially developed sealed ring chain using Renthal's Self Regulating Seal (SRS) technology to increase the service life of the chain in road applications. The special SRS ring is pre-loaded during assembly creating a spring effect. As the chain wears, conventional O-rings and X-rings lose their seal; however, the SRS ring has the ability to unload itself during use keeping a tighter seal against the side plates. This offers increased longevity as the specially formulated grease remains trapped around the critical pin and bushing area longer while also keeping dirt, water and other contaminants out. SRS Ring technology enhances chain flexibility and offers smoother operation than standard O-ring chains. Larger diameter pins manufactured from specially enhanced alloy steel improve the resistance to shock loads and wear. Quad riveting process on each pin increases the tensile strength of the chain. Thicker inner- and outer-plates increase the fatigue life of the chain. Gold-anodized side plates help prevent corrosion.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.

The specially formulated grease is trapped in the critical pin and bushing area, while contaminants, dirt, and water are kept out. SRS Z-ring road chains feature high-alloy steel plates and pins, solid bushings and rollers, shot-peened side plates for added strength, and gold side plates. A special quad riveting process and thicker outer plates increase overall strength. The chains come pre-stretched and include a pair of latex gloves for a mess-free install.
