# AD244SE350 - Self-Exciting AD244 Series, Extreme Duty, 350 Amp, Dual Rectifier Alternator
The Larger AD-244 will bolt directly in place of your existing 100-105 amp AD230 alternator without any modification. It is recommended that you upgrade the battery wire that connects to the rear of your alternator. You need a bigger wire to get the power out of the alternator and into your battery and electrical system. Our new generation of AD-244 are equipped with a Heavy Duty (HD) "copper" heat sink rectifier and oem quality regulators that just do not go bad! Along with perfectly balanced rotor and stator combinations for the best performance.
