• DIY Valve Seating: Worn valves cause compression loss and poor engine performance. This valve lapping tool lets you lap your valves back to a proper seal. The suction cups hold the valve while you rotate it against the seat. A shop quality job done in your driveway
• Spare Cups for Long Use: Eight replacement suction cups are included with this lapping kit. You get two of each size (0.6 inch / 0.8 inch / 1.1 inch / 1.4 inch). The cups wear down over time from friction. Having spares means you keep working when the originals start to lose grip. The tool is very easy to carry
• Two Tool Lengths Included: This valve lapping kit comes with an 8 inch tool fitted with 0.6 and 0.8 inch cups, and an 8.6 inch tool fitted with 1.1 and 1.4 inch cups. The different lengths help you reach valves in various cylinder head designs. A complete set that covers most engines. Dual-head design for greater flexibility
• Nylon Handle: The handles on this valve grinding tool are made from durable nylon that withstands the back and forth motion of lapping. The lightweight design reduces hand fatigue during longer lapping sessions on your workbench. The comfortable handle features a grooved design for easier handling and a non-slip grip
• Rubber Suction Material: The suction cups on this valve lapping tool are made from rubber that grips the valve head securely. The material provides good suction for effective lapping action. A durable set that stays in service long after ordinary rubber cups have failed on your workbench. Easy to swap when they wear out from normal use
