the price is high but states it does fit you bike HONDA GOLDWING SE GL1800 REAR DIFF, DISC input shaft. From a 2004 GOOD USED CONDITION 1189 ACTUAL MILES Neighbor commissioned his bike to a trike conversion otherwise he could never put anymore miles on it. See our other Goldwing parts
This Rear Diff (ONLY) is retailed new for over $1.387.07, The Rear Brake Rotor is retailed new for $362.04, BuyItNow price is only $277.00
The rear end will fit, but there may be differences in the brake line brackets. I don't believe the driveshaft from an 04 will fit an 06. There is a slight difference in length of the drive shafts from an 04 to an 06.
