Chevy Small Block Single-Groove Steel Short Water Pump Pulley - Chrome

This is a single-groove steel pulley with a chrome finish, built for Chevrolet small block V8 engines running a short water pump and V-belt accessory drive. It bolts to the short water pump's 5/8" pilot bore using the standard 4-bolt mounting pattern, giving you a clean, durable replacement or upgrade pulley for small block Chevy front-drive systems.

This pulley fits Chevrolet small block Gen I engines equipped with a short water pump, a configuration commonly found on early Camaro, Chevelle, Nova, Impala, El Camino, and C10 truck accessory drives, as well as small block engine swaps and street rod builds using a V-belt drive. It is not designed for long water pump configurations or serpentine belt systems — confirm your water pump style and belt system before ordering.

Steel construction with a chrome finish supports reliable belt tracking and a clean front-drive appearance. Verify groove count, bolt pattern, pulley offset, and belt width before installation. Hardware is not included. Sold individually.

 

Steel Pulley Matched to Small Block Short Water Pump Dimensions
Built from steel with a chrome finish, this single-groove pulley is sized to the 5/8" pilot bore and 4-bolt pattern used on Chevrolet small block short water pumps, giving you precise belt alignment and a durable replacement for a worn or mismatched pulley.

Proper Pulley Fit Keeps Belt Tracking True and Coolant Flowing
A mismatched water pump pulley can throw off belt alignment, leading to belt slip, noise, and uneven water pump speed — which affects coolant circulation. This pulley's 7.100" outside diameter and single-groove design are matched to small block short water pump specs to help keep belt tracking consistent.
