Yella Terra Holden VF LSA Heavy-Duty Solid Supercharger Isolator Coupling — YT 1521
$127.00
The Yella Terra YT 1521 is a solid high-performance replacement for the factory spring-style isolator inside the LSA supercharger snout. The isolator forms the mechanical link between the upper drive pulley and the blower rotors.
Why Yella Terra replaces the factory isolator
- The original spring-style coupler is known to develop rattle at idle and partial throttle.
- Wear can groove the supercharger shaft and create debris that may contribute to shaft-seal failure.
- Increasing the blower drive ratio places additional load through the factory isolator.
- Yella Terra warns that the original coupler is not suitable for the increased load created by boosted overdrive combinations.
YT 1521 heavy-duty solid coupler
- Solid one-piece PEEK high-grade thermoplastic construction.
- Direct replacement for the original isolator.
- Designed specifically for high-boost and high-load applications created by increased supercharger drive ratio.
- Recommended by Yella Terra for use with its GTS / LSA boost-upgrade packages.
Installation: The coupling is installed inside the supercharger snout. The snout, shaft, bearings and seals should be inspected whenever the drive assembly is opened.
