No car can run for long without an alternator, but these big old clunky devices can take up a lot of space on your engine. This can be especially problematic if you’re trying to say, drop a big block engine into a car designed only for small blocks. Suddenly you’re stuck with the realization that that old stock alternator just won’t fit.

If that is the case with you, then maybe you should check out Powermaster Performance’s compact “5×5” racing alternators. These alternators pack the biggest proverbial punch in the smallest package possible, delivering 90+ amps at 7,500 RPM while measuring less than 5-inches tall and deep. It has the highest output at idle of any alternator of this size or weight and has been “0” balanced.

Even better, this compact alternator features side battery post. This simple feature allows the alternator to be mounted with 1/8^th of an inch to the engine block. It doesn’t get much closer than that!

• Compact alternator measures less than 5-inches tall and deep
• Provides 90+ amps at 7,500 RPM
• Side battery post allows alternator to be mounted as close as 1/8th inch to the block
