URD SuperGrip Supercharger Pulley 70mm Magnuson TVS-1320 5VZ

This pulley fits the newest Magnuson supercharger for the Toyota 3.4L 5VZ-FE V6 that has the new TVS-1320 rotor pack.   It will not fit the older TRD or Magnuson MP-62 superchargers.

The URD SuperGrip Supercharger pulleys for the Toyota 3.4L 5VZ-FE V6 use an advanced design to enhance performance, reduce belt slippage and extend supercharger belt life. These 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 Magnuson 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 two advanced features to enhance belt traction.

• Tall outer 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.
• Modified rib profile: improves the contact pattern between the ribs and the belt for greater traction and torque transfer.

These features result in the most advanced supercharger pulley design available and really make the pulley look awesome!! All the URD SuperGrip pulleys are finished in a hard anodizing in bright URD red.

URD offers three different size pulleys. For a daily driven truck, we recommend the 70mm. This is the best overall size that will give you approximately 1.5-2 PSI more boost than the stock 75mm 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 70mm normally will give approximately 1-1.5 PSI more boost over the 75mm 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.
