Major advantages of upgrading to this part/product:
1. Made with a quality light weight high tensile strength aluminum 6061 T6 for greater durability and more stable to use. The middle part of upper arm has upgraded to #45 steel to so the arms are stronger and prevent collapse but keep a light weight at the same time.
2. Rear knuckle arms are inserted with POM collar so the axle rotation and the upper and lower arms swing more smoothly.
3. Upper arms used a tie rod design with counter-clockwise threads in order to adjust the length to suit different road condition.
