5VZ 2.1" SuperGrip Supercharger Pulley
There are three different size pulleys. For a daily
driven truck we recommend the 2.2" pulley see part number 1016186 5VZ 2.2" SuperGrip Supercharger Pulley
. This is the best overall size
that will give you approximately 1.5-2 PSI more boost than the stock
2.37" size pulley and is safe for long term use when properly fueled and
tuned. This should only be used with the highest octane fuel available
in your area.
This part is the 2.1" this pulley normally will give approximately 1-1.5 PSI more
boost over the 2.2" pulley. This should be used with 93 octane fuel

The SuperGrip Supercharger pulleys for the 5VZ TRD Supercharger use an advanced design to enhance performance, reduce belt slippage and extend supercharger belt life.
The SuperGrip Supercharger pulleys are smaller than stock and
increase the impeller speed and boost pressure to the engine. When this
is combined with the proper fuel upgrades and tuning you will have
The TRD Supercharger for the 5vz uses a small 4 rib drive belt.
Transfering the torque needed to drive the supercharger from a 4 rib
becomes more difficult when the pulley size is reduced. To address this
problem the SuperGrip design is used.
The SuperGrip design has three advanced features to enhance belt traction.
- Tall outer ears
- Modified rib profile
- Slit and hole design
The tall out ears grab the outside edges of the belt and make the 4
rib belt act like a 5 rib belt for greater traction and torque transfer.
The modified rib profile improves the contact pattern between the
ribs and the belt for greater traction and torque transfer.
The slits and vent holes in pulley gives the air that can get
trapped between the belt and pulley a way to escape to the bet stays
nice and tight against the pulley and eliminates a "hydroplaning"
effect. This gives the best possible traction and torque transfer.
These features result in the most advanced supercharger pulley design available and really makes the pulley look awesome!!
All the SuperGrip pulleys are finishing in a hard anodizing in bright red.
SuperGrip pulleys for the 5vz TRD Supercharger require proper
