CSW1872 Shock Spring Cups

This product is a set of four shock spring cups designed for Custom Works big bore shock systems, used to properly seat and retain the shock springs on the shock body. These cups act as the lower spring perch, helping keep the spring centered and preventing it from slipping or binding during suspension travel. They are commonly used in Custom Works racing platforms where consistent suspension response is important for handling and traction. Made from durable nylon material, they are lightweight while still offering enough strength for repeated compression cycles. This is a direct replacement wear item for big bore shock assemblies used in oval and sprint racing setups.
