250 Amp – Nissan TB45

This high-output alternator is designed to be a direct OEM replacement for the TB45E and TB45S (4.5L gasoline) engines. This heavy-duty alternator generates a maximum of 250 Amps at normal driving speeds and produces 185 Amps at idle.

The XP series of SBC alternators are assembled using DENSO components and produce the highest idle output. They feature a larger housing while still retaining OEM fitment without any modification required. They run cooler and are virtually indestructible. This alternator is designed to be an exact replacement to the OEM alternator for the TB48DE engine.

A precision CNC 6061T6 aluminum pulley with a .002 hard anodized coating is installed on each alternator for maximum output and durability.

This alternator comes with an unprecedented full two year warranty.
