Description
Aeroflow Holden V8 High Torque Compact Starter Motor (1.4kW / 1.9HP)
Engineered for high performance, maximum header clearance, and effortless cranking under high compression loads.
High-Performance Engine Cranking
The Aeroflow AF4250-5310 XPRO High Torque Compact Starter Motor is engineered specifically for Holden V8 253 and 308 engines fitted with a 153-tooth ring gear. Powered by a high-output 1.4kW (1.9HP) Hitachi-style motor utilizing a heavy-duty 4.44:1 gear reduction ratio, this unit delivers exceptional cranking force while drawing lower current than standard starters.
Featuring a multi-angle billet aluminium mounting block, the AF4250-5310 can be indexed into various positions to clear aftermarket exhaust headers, large-capacity oil pans, and chassis rails. Built with high thermal resistance and a protective black powder-coated finish, it is fully serviceable and designed for extreme competition and high-performance street-strip applications.
