The increased piston and wear band height is designed to fully overlap external bypass ports, delivering more seamless and consistent damping performance. The greater wear band contact area provides an improved seal, making valving more effective while also increasing strength and rigidity. Enhanced compliancy allows for a smoother transition between bypass zones, plus increased bottom-out performance.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eSold as a Kit \u0026amp; \u003c\/strong\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Piston w\/ O-Ring\u003c\/li\u003e\n\u003cli\u003e(1) Wear Band\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003e \u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003e\u003cstrong\u003eEXCEEDING 110%\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003eThe increase in wear band height\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003eprovides full coverage of the bypass\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003eports, eliminating a brief drop in force\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003epreviously experienced with standard\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003epistons as they travel across each\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 0in;\" class=\"MsoNormal\"\u003eport.
