Spare Piston Rings

Includes upper compression rings, secondary rings and oil control rings
Top compression rings with Barrel Face profile
Promotes heat transfer between the piston and the cylinder wall
Controls combustion chamber gases by allowing the piston to transfer energy to the crankshaft.
Second compression ring with inverted torsional conical face
Promotes side sealing preventing oil passing behind the ring, improving oil consumption.
Reverse-turning ring with machined conical face replicating the lower scraper edge of a positive torsional ring.
Three-piece Flex Vent oil control rings
The three-piece design enables rails to be manufactured with a reduced cross-section for better fit to the hole.
Provides even pressure via four steel guides and two expanders, ensuring positive oil control.
Manufactured in the USA
Due to the thermal conductivity and design of KB pistons, special attention must be paid to the top ring end gap. Read the instructions included with the piston for correct installation.
Includes sufficient rings for two pistons (unless otherwise stated).
Two rings per slot, except on the rails, which have two rings per expanding ring.
The kit includes:
• 2x upper compression rings 0.0625"
• 2x secondary compression rings 0.0625"
• 2x expansion rings
• 4x steel rails
