The hub is made of stainless steel which is guaranteed not to rust or corrode.  The pulley is
machined from T6061 billet aluminum of the highest quality and are available in either a machined or
polished finish.  This kit includes a hub, pulley, 7 stainless steel screws (5 required + 2 extra), an
allen wrench, and installation instructions.

These are available in any size you would like from 2.3 to 3.9"

Here is a quick summary of the modifications necessary to run different sizes:
  • 3.6 - 3.8: No modifications necessary
  • 3.5 Cold air intake, cooler thermostat and mild exhaust work (u-bend delete, cat back)
  • 3.4 All the above plus better flowing exhaust(hi-flow/no cat, 3" down pipe) and colder range
    plugs (AL104's)
  • 3.3 All the above plus a very free flowing exhaust (headers), and some port work (TB, heads,
    Supercharger) or camshaft
  • Smaller than that will need more extensive engine and cooling modifications
  • If you'd like a pulley size not listed in the drop-down menu, please email us and we will
