This Auto Specialties VG30 under drive pulley has been proven to add huge Hp and low end torque to both the Nissan 300zx Twin Turbo and the N/A. On the Twin Turbos it helps the engine rev up quicker which makes for a quicker spool up on the turbos and on the N/A it also helps the engine rev up quicker for better low end grunt.
H.I. Water pump pulley addresses a cooling problem that can surface when you install an Unorthodox Racing, ASP, ATI (street version) or similar sized under drive crank pulley.
Unorthodox Racing Ultra Street (Ultra S) lightened under drive crank pulley. Made of lightweight Premium U.S. made 6061-T6 billet aluminum to ensure consistency of the material's strength and balance.
Unorthodox Racing Ultra Street Set (Ultra SS) pulleys. Made of lightweight Premium 6061-T6 billet aluminum to ensure consistency of the material's strength and balance. CNC machined to .001". This is the complete Street pulley set that consist of the Ultra S crank pulley as well as all of the Ultra A accessory pulleys for each application.
Race Damper is built around ATI's large diameter 6.325" inertia ring to control high-RPM harmonics.

- 6% overdriven PS pulley
- Rated at 1000 HP capability
- Weighs 7.24 lbs
- Removable crankshaft hub
- SFI 18.1 approved
STILLEN has long manufactured precision pulleys for our supercharger kits. Each pulley is machined from 6061 aerospace grade billet aluminum with a bold new design to maximize performance, strength and minimum weight. 304 stainless steel sleeves are used for main seal contact points for durability.
Gates Micro-V Belts outperform other V-ribbed belts because they are truncated. This shorter profile gives the new Micro-V Belts increased flexibility, reduced heat buildup and allows them to operate at extra high speeds on smaller diameter sheaves.
