Part #: EDL3-ALTKIT107

HIGH OUTPUT EnDuraLast III Alternator Charging System with heavy duty stator and rotor with increased electrical output. The EnDuraLast III uses the same Bosch design with upgraded diode board, regulator, stator, and rotor. Replaces the under performing Bosch charging system with a 107mm outside diameter stator (timing cover side) and stator frame side outside diameter is 107.5mm on BMW R Airhead's from 1976-1995. The EnDuraLast III charging system will reach charging voltage sooner than any other BOSCH style charging system we offer. Ideal for the urban low RPM rider.

Important Note: use the fitment table on the APPLICATION TABLE tab to identify the correct kit size before ordering. You can measure the inside (timing cover side) and outside (stator frame side) diameter of your stator ring with calipers or use the BOSCH Alternator part number.

Some customers report increased component failure when use of ODYSSEY and/or LITHIUM IRON batteries. These batteries are not recommended or supported for warranty replacement of components. Conventional wet acid or sealed AGM (Absorbed Glass Mat) batteries are known to work well with all conventional charging systems.
