The MST FXX-D Aluminum HT Upper Arm is an optional upgrade for the FXX-D, FMX-D, RRX-D, RMX-D, FSX-D and XXX-D models. These C & D position front upper arms are a direct replacement for the stock part (MXS-210058), and will increase durability, reduce flex and help to increase suspension precision. Plus, the availability of a variety of colors will give you the option to give your MST ride a custom look. Package includes left and right side HT upper arms, hinge pins and hardware.
For the ultimate in strength and precision, we recommend you combine these with the A & B upper arm set (MXS-210507).
