Blade Fuse Panels

Classic Retrofit panels are a direct replacement for the existing fuse system on your classic 911

Upgrade Alternators

Classic Retrofit's high output alternator developed in conjunction with WOS Performance is the ONLY alternator available for the 911 that can deliver a continuous current in excess of 100A.  The alternator can deliver 75A at idle. The design uses all new 6 phase internals inside a billet alloy casing that bolts into the 911 fan housing. It is a direct fit to early cars and requires spacers to fit mid and later years. Other 'rewound' alternators claim high output but cannot reject the heat generated by the windings for a sustained period.
