FIAT 500 Lightweight Underdrive Crankshaft Pulley Kit - ABARTH/ 500T/ 500L Models

Would you like to have an improved throttle response, and a LOT more fun driving?

MPx has spent nearly 6 months of testing, revising, testing and revising further to make this piece a great addition to your  500 ABARTH/ 500T/ 500L. MPx has driven thousands of miles testing this part on an ABARTH. Thousands of miles have been driven with this item to not only verify performance gains, but also reliability. Seven different prototypes were tested before the final version was picked and put in to production to make sure that you have the absolute perfect pulley kit.

Below is the infromation provided by MPx:*

Would you like to pickup another 6-8 horsepower and torque at the wheels in your FIAT 500 ABARTH/ Turbo/ 500L?

The stock pulley weighs in at 3.35 lbs. In comparison the MPx lightweight underdrive pulley weighs in at 1.8 lbs. Saving nearly 1.6 lbs of sprung mass off of the crankshaft allows for a quicker revving engine, and less power loss spinning dead weight.

By the use of this kit MPx was able to underdrive accesories by 20% without affecting the AC and Alternator. This means less power is robbed from the crankshaft for the AC and Alternator. At the same time they still function normally. Cold AC, Normal Alternator Performance and no Check Engine Lights!

MPx gained solid horsepower and torque across the entire RPM Range, not just power up top, or on bottom. This makes a difference you can feel.

This Pulley Kit is consists of an Outer Billet Pulley, Tone Wheel, Longer Crank Pulley Bolts and a new Gates Belt.

When changing the pulleys out, the 1.4L has an allignment guide pin with offset mounting holes that will make it impossible to install incorrectly. Installation is not difficult and any good mechanic, or home mechanic should be able to install this in under an hour with basic hand tools all from within the passenger side wheel well.

This entire kit is manufactured in USA. 

The Outer Aluminum Pulley is hard anodized for long life and great looks. A Trigger Wheel is made out of steel and is zinc coated. A brand new Gates belt and three bolts are also provided in this kit.

An illustrated install guide is included with each kit.
