Detailed Product Overview

MPA Electrical 3733MS is a remanufactured starter intended for GM light-duty and heavy-duty trucks, full-size SUVs, and utility models across the 1982-1994 model years. Fitment includes Chevrolet K1500, K2500, K3500, Blazer, K5 Blazer, Suburban, and V-series trucks, plus GMC K1500, K2500, K3500, Jimmy, Yukon, and related C/K applications. Several listings note a starter case diameter that steps down at the end, and some applications specify a small drive end opening to help prevent debris from entering the starter.
