New Protomotive Lightweight Underdrive Crank Pulley Kit Porsche 996 997 Turbo

Description

New Lower Price! More Power and reliability for your Porsche 996 and 997 Mark 1 Turbo.
Fits 2001 to 2009 Turbos and Gt3s.
Under-drive for more Power!
Shrink fit for the highest reliability (must be heated to 250degF to install).  We've also increased the mounting depth to improve stability.
All cars with lightweight flywheels and clutch packages need this or you'll ruin your crankshaft when your front pulley spins off.
Provided with the proper length high grade bolt and serrated washer. (Other kits we've seen use a stock length bolt that's too short when used with the thicker, aluminum pulley.
Provided also with proper length serpentine belt.
We've given you the convenience of 5mm and 4mm pins for 4.0 gt3 cranks (80.4 stroke)
We've also given you both sets of timing marks to line up with the case, and the new pointer on 996/997 Turbos at TDC, 120 deg and 240 deg.
The marks are differentiated by either a triangular cutout, or square, so it's easy to see where you're at.
Blue anodized for long life.
Super lightweight design for the lowest inertia.
