This is GNP's T-6061 solid aluminum, hard anodized
Timing Belt Guide. This Timing Belt Guide has been
designed to be wider and stronger than the stock
Subaru piece, while keeping the proper tolerance
to ensure smooth timing belt operations at all times.
What this does is help eliminate what's called belt
whip. Which could lead to very bad things for your
motor. Belt whip is caused by changes in torque that
your motor goes through, usually by being hard on and
off the throttle. We have engineered this piece with
an extended length and width to apply more coverage
for the timing belt and hard anodized it to provide
a smooth belt track. This part is a direct
replacement for the stock flimsy piece, and can be
added to just about any DOHC Subaru 2002 and newer.
Because you want to protect your investment while
enjoying it to it's fullest.
