A golf cart rear axle, often referred to a differential, helps propel your Yamaha G1, G2, G8, G9, G14, G16, G19, G22, and G29 the drive gas or electric golf cart. A differential slows the rotational speed of your clutch or electric motor before it hits the rear wheels. Each wheel turns at different speeds during turns and you need a rear axle differential to allow your cart to make this transition. Without a differential, your carts ability to turn would not be functional. We carry replacement passenger side rear axles and drivers side rear axles for all gas or electric Yamaha golf cart models.
