Powermaster Duramax Alternator

Fits 2007.5-2010 LMM Duramax

Part# 58302W

Just by adding a few electrical accessories such as driving lights, auxiliary cooling fans, or a mega-sound system you can quickly exceed the capacity of your alternator. POWERMASTER has the solution - high output alternators that bolt in place of the OEM alternator. They feature a slightly larger case that bolts to all factory brackets and use the same belt. POWERMASTER has reengineered the power curve to deliver up to 50% more output at idle. Every POWERMASTER high output alternator is tested and comes with a proof of performance tag.

Features:

• Dual Internal Fans For High Efficiency And Maximum Cooling
• 220 Plus Amps At Top End/150 Plus Amps At Idle
• OEM Hookup
• Individually Dyno Tested with Proof of Performance Guarantee
• High Output Replacement For Lower Amp Units
