Description
Designed & Manufactured in house, We have designed our latest range of LSA Top Pulley upgrades to increase boost & horsepower without causing the possibility of belt slip.
The other benefit of our kit is that removes the failure prone spring loaded pulley coupling.
Our 3 pulley sizes make more Boost than other Kits available
So if you want the most from your Boost upgrade kit you should choose GM Motorsport Kit.
Those looking for Maximum Boost without snout modifications should purchase our 62mm pulley.
It is the smallest pulley to fit without modifications to the snout in the World
This means more Boost for your LSA
***Please note, the 60mm pulley will need the supercharger snout machined approx 4mm to fit ***
