Single Alt. Pulley

The Single Alt. Pulley by TRANS-DAPT is a vital engine accessory designed for builders and enthusiasts focused on precision serpentine belt management in custom or modified powerplants. This pulley is particularly useful for those working on engine swaps, fuel-injected retrofits, or high-performance crate motor installations.

Engineered for applications that prefer a single-belt configuration, the pulley measures 4.7 inches in diameter and is constructed to OEM standards. It ensures reliable torque transfer and consistent belt tension across the alternator's input shaft, which is crucial for smooth operation and minimal harmonic vibration.

Installers working on street rods, muscle car restorations, and custom fabrication projects will find this single-pulley solution beneficial, especially when factory multi-accessory bracket setups do not fit their design vision or available space. Compatibility will depend on the specific alternator used in the application.
