Pulley Ratio Information:
Calculate pulley ratio by dividing the diameter of your crankshaft pulley by the diameter of the alternator pulley.

• Example: A 7.48-inch crank pulley (Stock LS) with a 2.9-inch alternator pulley yields a 2.58:1 pulley ratio (7.48 ÷ 2.9 ≈ 2.58)
• This means the alternator will spin about 19,350 RPM at 7,500 engine RPM
