YELLA TERRA'S OWN LSA SOLID HIGH PERFORMANCE ISOLATOR COUPLER

 A MUST HAVE WHEN INCREASING BOOST TO YOUR LSA!

The supercharger isolator coupler is an important part of the LSA supercharger drive assembly. Located in the supercharger snout creating the link between the top drive pulley and the blower rotors.

The original isolator contains a spring mechanism and is notorious for rattle at idle or partial throttle and wearing a groove on the supercharger shaft, creating debris that will eventually cause the shaft seal to fail. 

More importantly YellaTerra's Solid Coupler is a must when adding boost. The original coupler WILL NOT handle the extra load created when you start to overdrive your blower sytem to add boost. The original coupler will fail with just moderate boost increases, causing the blower assembly to lock up!

YellaTerra's HD Solid Coupler is a solid piece of PEEK high-grade thermoplastic and installs as a direct replacement for the original.  Specifically designed to handle high boost, high load applications generated by increasing the superchargers drive ratio.

We recommend our HD Solid Coupler to be used with any of our GTS LSA Boost Upgrade Packages.
