The Pulley V-Belt 3in Dia 1.125in Bore by Jones Racing Products is a precision-engineered component designed for high-performance engine accessory drive systems. This 3-inch diameter pulley is essential for enthusiasts and professional mechanics looking to upgrade engine bay efficiency in custom engine builds and race applications.
Manufactured with precision machining, this pulley maintains tight tolerances and concentricity, which are critical for running serpentine belt systems at high RPMs. The 1.125-inch bore accommodates standard crankshaft keyway specifications, ensuring secure hub-to-shaft engagement and proper load transfer during operation.
Mechanics and engine builders upgrading cooling capacity, electrical charging, or fuel circulation will benefit most from this pulley when reconfiguring serpentine belt drive ratios. It pairs well with matching crank and idler pulleys to establish optimal accessory drive ratios, enhancing performance in both naturally aspirated and forced-induction engines.
