Product Details

The HKS 12999-AK002 is a replacement and upgrade pulley designed for use with the HKS GT Series centrifugal supercharger system. Measuring 85mm in diameter with an 8-rib belt groove, this pulley allows tuners to fine-tune boost levels by swapping pulley sizes within the HKS GT Supercharger lineup.

The HKS GT Supercharger system delivers lag-free, linear forced induction power across the entire RPM range. Unlike turbochargers, the centrifugal design allows torque to build smoothly from low to high engine speeds, making it an ideal forced induction solution for street and track applications. This pulley is compatible with HKS GT Supercharger universal models including the GTS4025, GTS7040, GTS8550, and GTS8555.

Key Features:

  • 85mm diameter pulley
  • 8-rib belt configuration for secure, high-power belt engagement
  • Black finish
  • Designed for use with HKS GT Series centrifugal superchargers
  • Compatible with universal supercharger models GTS4025, GTS7040, GTS8550, and GTS8555
  • Supercharger unit not included

Pulley sizing directly affects supercharger boost output — a smaller pulley increases boost while a larger pulley reduces it, allowing precise tuning for your specific power goals. This 85mm unit is part of HKS's range of supercharger accessory pulleys, available in multiple diameters to suit various build requirements.

good so far. Totally.

Best price to be found, no ridiculous shipping costs.

I had a great first time experiance with Autoplicity. My K&N Filter came on time just as promised and saved me about $40 over my local Autozone including shipping! I will be back

Easy and Pleasant, Fast Shipping Great Product. THanks

So far so good! :)

AT THIS TIME "GREAT TRANSACTION"

Easy

The resonator I ordered arrived at my house slightly bent, but I called Autoplicity and they sent a replacement by next-day-air, so I was happy about that. It's a little hard to reach people there when you need to get a problem resolved, but in the end it all worked out.

Thanks

I shopped around on the internet and Autoplicity was the most reasonable price for the same quality brand name locking hubs i was looking for. Only con was i read on internet they had free shipping and that wasn't so on my order which was disappointing.

Great Price, item descriptions could be improved to be clearer.

Amazing prices!
