When you order a 2-speed axle it comes on a pallet (about 150#) as shown. EZGO is 19 spline count. CLUB CAR 2 SPEED LIMITED SLIP REAR AXLE ASSEMBLY 2-SPEED- (10 TOOTH) 9.999 &19.93 RATIO Lug nut to lug nut is new - so you have new brake components, and heavy-duty axles and hubs.  A six-inch lift is built in.  The column shifter is extra. Club Car axles (ten spline) come with an adapter plate. Make sure that it is oriented correctly for the motor to fit properly.Our Axles come dry from the factory. We suggest using Trans X Posi Trac Limited-slip gear oil additive. Put the entire 7fl oz tube in and then top off with 80w90 gear oil (Detailed instruction at bottom of this page.) Then you can start the break-in process. Drive your buggy in tight circles and figure eights. Do this for about 15 min. 2-4 times to force the oil in between the plates.
