If you own the LHT / Griptech H22 Kit with high the boost Pulley , and want the stock boost option,
this is the standard size pulley.
This is the pulley only, it bolts to your hub.
You can easliy change between the high boost and standard booost by removing the Allen bolts only.
GripTec® Micro is a micro ablation machining process. Our micro machining capabilities are near limitless and we apply our technology to give the target component an engineered surface design that optimizes the safest most aggressive gripping force possible. Our multi directional machined ridges and valleys offer up more than just maximum gripping force they also act as escape ducts for trapped air and debris further helping in the mating of the target surface and belt.

Belt slip is a very common issue on supercharged components. In fact some units cranking out as much as 14-16 psi can take up to 200hp to drive. Often the drive systems are plagued with slippage issues and builders find themselves moving to noisy cog systems, where belts have shorter life spans, are difficult to find at just any parts store and they can create more heat through the frictional movement of the cogs.
Belt slip isn't always noticeable. Often belt slip is noticed when the system squeals, squeaks or boost falls off. Did you know that naturally the belt can slip a very small percentage even on NA vehicles, one major factor to belts wearing. Belt wrap does play a key factor in minimizing belt movement but when it comes to driving a supercharger is hard to fully eliminate with just surface contact. .
