Aeromotive 21101 AER Pulleys

Special order — contact us for details

Description:

This billet crank pulley uses a documented 34-percent underdrive configuration. A crank pulley transfers crankshaft rotation through a belt-driven accessory arrangement, and the underdrive percentage is the principal specification distinguishing this pulley from other ratios. The LT1 designation is omitted from customer copy because the separate fitment process owns engine references. One pulley unit is supplied.

Key Features:

• Billet crank-pulley construction
• Documented 34-percent underdrive configuration
• Supplied as one pulley unit

Fitment Note:

Please consult a professional before purchase to confirm the correct fitment for your vehicle.
