URD SuperGrip Supercharger Pulley 2.1" for 3.4L Toyota Trucks

Original price was: $129.00.Current price is: $99.00.

The URD SuperGrip Supercharger pulleys for the 5VZ TRD Supercharger use an advanced design to enhance performance, reduce belt slippage and extend supercharger belt life.

The URD 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 increased performance.

The TRD Supercharger for the 5vz uses a small 4 rib drive belt. Transferring the torque needed to drive the supercharger from a 4 rib becomes more difficult when the pulley size is reduced. To address this problem URD developed the advanced SuperGrip design.

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 URD SuperGrip pulleys are finishing in a hard anodizing in bright URD red.

URD offers three different size pulleys. For a daily driven truck we recommend the 2.2” 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.

The 2.1” normally will give approximately 1-1.5 PSI more boost over the 2.2” pulley. This should be used with 93 octane fuel minimum or used for vehicles at high elevations.

URD SuperGrip pulleys for the 5vz TRD Supercharger require proper fueling and tuning. URD has proven fuel and tuning solutions available. Please review the fuel upgrade kits we offer for your vehicle.

Proceed smartly, and BOOST ON. Ask us a question if you don\’ know what is best for your application!

Note- The TRD Supercharger for the 5VZ-FE 3.4L engine uses a slip fit type pulley that is held on with a shaft nut.  It does not require the use of the URD Press Fit Pulley Tool.

Note- In November 2021 due to parts shortages, Magnuson has assembled some of the 3.4L supercharger systems with a different style input shaft and that required a press on type pulley.  If your supercharger does not have a large nut holding the pulley in place you do not have a slip fit style supercharger pulley and this pulley will not fit.

    Just installed the smaller pulley and took the 4Runner for a test drive. All I can say is “Oh my!”
    Wheel spin in third gear while climbing a hill at 55mph in the rain. Looking forward to a dry day.
