Billet Aluminum 1.8T/2.0 Alternator Pulley
Ditch the heavy 1 lb clutched alternator pulley
in favor of this billet aluminum version designed using high tech CAD software
and crafted on one of our CNC's to reduce the rotating mass and get every last
hp out of your engine. Our version weighs 5 times less than the OEM pulley, and
because its made on a CNC has a total runout of less than .001"! All this means
a smoother and quiter engine that revs quicker off idle. Comes complete with
high grade nut and thrust washer. Installs quick but please follow all
Volkswagen installation instructions.
Aluminum 1.8T/2.0 Tensioner Pulley
Plastic may have made the bean
counters at VW happy, but it has no business as a tensioner pulley on your high
strung VW motor. Ours is extremely light weight and contains a precision 20K RPM
SKF bearing that will perform more quietly and far outlast the OEM plastic
pulley. Installation is a breeze — simply release belt tension, remove the
tensioner pulley bolt, and swap ours in. Note - the torx bolt loosens
counterclockwise (normal bolt). Please follow all Volkswagen installation
instructions for installation.
Lightweight Billet 1.8T/2.0
Non-Underdrive Crank Pulley
Lose the boat anchor of that OEM steel crank pulley with this 230
gram lightweight billet aluminum version. It is the lightest crank pulley out
there and will allow the engine to spool up faster while reducing inertial
losses caused by the overweight OEM pulley. This pulley is NOT underdrive and
will therefore not underdrive the alternator and cause charging problems. For
underdrive applications, check out our specially designed underdrive power
steering pulley below.

A lightweight billet aluminum version of the OEM power steering

without affecting other accesories. This pulley will reduce the parasitic losses
from the power steering pump at higher rpms by preventing pump over-rotation.
For those seeking an underdrive set up, this is the pulley to get! Uses the OEM
