GruvenParts.com offers ultra sleek and super lightweight crank, water pump, tensioner, power steering, and alternator pulleys for your 24V VR6 engine. These pulleys are precision CNC'd from aircraft grade billet aluminum. Complete pulley set reduces the engines rotating mass by over 8 lbs !!
PLEASE NOTE - THE ONLY PULLEY THAT IS UNDER-DRIVE IN THIS SET IS THE POWER STEERING PULLEY. All others are normal OEM drive. In our experience, the only pulley safely capable of being under-driven is the power steering pulley. Installation of any or all of our pulleys does not require different length belt, and will not affect aftermarket supercharger installations.
Lightweight Billet Aluminum VR6 Tensioner Pulley
Plastic may have made the bean counters at VW happy, but it has no business as a pulley on your high strung VR6 motor. Ours is extremely light weight and contains a precision bearing that will far outlast the OEM. We even use a snap ring to install the bearing, so if replacement was ever needed, it's a breeze. Fits all of the 24V VR6 engines.

Lightweight Billet Aluminum 24V VR6 Water Pump Pulley
The OEM steel water pump pulley is stamped which creates internal stresses that eventually cause the pulley to crack at the sharp bend radius. Needless to say, you don't need this problem on a hot running VR. Ours is machined from a solid block of aluminum with generous corner radii and is therefore many times stronger than OEM. Weighing in at a scant 250 grams, its less than half the weight of the stamped OEM steel pulley. Fits all of the 24V VR6 engines.

Lightweight Billet Aluminum 24V VR6 Crank Pulley -- Normal Drive, Not
It's time to lose the boat anchor of the steel Audi and VW VR6 crank pulley! This 500 gram lightweight version is the lightest crank pulley out there! It will allow the engine to spool up faster while preventing inertial losses caused by the overweight OEM pulley. Comes with a specially machined replacement key for a perfect fit. Note this pulley IS NOT under-drive!! Fits all of the 24V VR6 engines.
** OPTIONALLY Upgrade to a FLUIDAMPR Crank Pulley in place of the Gruven Billet pulley
Lightweight AND Under-Drive Billet Aluminum 24V VR6 Power Steering
A lightweight billet aluminum version of the OEM power steering pulley, sized to allow a 10% reduction in power steering pump rotational speed. This will lessen the parasitic losses from the power steering pump at higher rpms by preventing pump over-rotation. Please note this pulley is non-ribbed which allows us to achieve the under-drive feature. Similar to the water pump pulley, ribs are not needed on the power steering pulley. This pulley has been proven by countless hours of track abuse with no problems whatsoever. Fits all of the 24V VR6 engines.
Lightweight Billet Aluminum Alternator Pulley
A 100 gram paper-light billet aluminum version of the steel OEM alternator pulley that lets the motor spin more freely. Complete your pulley set for a show quality engine bay. Fits all 24V VR6 engines.
