2008 New Manual Gasoline 4WD Sport axles made of solid steel. We have installments for all installment companies. Benefit of the axle? It withstands stepping on the gas, drifting, and deserts. The difference between the original and the sport: The original comes in two pieces connected together, and this is the reason for the frequent damage of the axles in the Xterra and its many flaws, unlike the sport, which is strong and lightweight. It is 3.5 kg lighter than the original.
