The new patented Silent Support System acts as a barrier between surfaces to reduce metal-to-metal contact that is common with aftermarket helper springs and typically results in unwanted metallic harmonics. The Silent Support System bushing provides a silent ride and will come standard on all Hellwig Product’s Helper Springs. The Silent Support System bushing is also sold separately as a retrofit upgrade for existing Hellwig Helper Spring kits.
