Designed for dimension- or specification-matched automotive applications, this JE Pistons piston pin lock supports the stated automotive service, performance, or replacement requirement. Selection depends on the exact application and mating components, so confirm the fitment table and manufacturer specifications before ordering.
Key Features
- Most JE shelf pistons include double spiro locks as standard equipment.
- These locks are installed by spreading the lock between 1/8" and 1/4" and rotating the lock into the groove in the piston pin boss.
- Wire locks tend to spread side loads over more of the piston pin boss area and are considered to be a stronger method of holding the pin in place.
- The advantage of tru-arc locks is ease of installation and they can be re-used unlike spiro locks, however they are not recommended for medium to high horsepower applications.
